How to use this glossary

This glossary is organized by thematic category rather than strict alphabetical order — related terms appear together for easier cross-reference. Each term has a short plain-English definition followed by an extended technical explanation where useful context exists. Many terms link to full articles on this site when we've written detailed analysis (e.g., the Bonus Buy and Drops & Wins hub pages, specific review deep-dives).

If you arrived here looking for a specific term, use Ctrl+F (Cmd+F on Mac) to search the page, or jump to the relevant category above. Each term has a stable anchor URL: /glossary/#rtp for RTP, /glossary/#bonus-buy for Bonus Buy, etc. — you can bookmark or share specific definitions directly.

Editorial philosophy: we write definitions in the language we'd use explaining to a thoughtful friend who knows statistics but isn't in the gambling industry. No marketing language, no "chase the big win" framing, no affiliate-oriented positioning. Where a term has mathematical nuance (RTP vs effective RTP with promotions, volatility vs variance, hit frequency as separate from RTP), we explain it. Where industry marketing creates confusion (bonus buy RTP actually being HIGHER than base game is counter-intuitive), we confront it directly.

Core Math & Statistics

RTP, house edge, volatility, and the probability distributions underlying slot, Plinko, Mines, and crash game math.

10 terms

RTP (Return to Player)

#

The theoretical percentage of wagered money a game pays back to players over the very long run.

Expressed as a percentage — e.g., 96.50% RTP means over millions of spins, the game returns €96.50 for every €100 wagered, keeping €3.50 as the house edge. Certified by labs like GLI or BMM. Critically: RTP is a long-run average calculated over billions of outcomes. Individual sessions vary wildly around this figure. Also note: Pragmatic Play slots ship with multiple RTP configurations (94.50%, 95.50%, 96.50%+) — casinos choose which to run, and players often don't know which version they're playing until checking the in-game paytable.

House Edge

#

The mathematical advantage the casino has over players, expressed as 100% minus RTP.

A slot with 96.50% RTP has 3.50% house edge. Over infinite play, the casino wins this percentage on average. Lower house edge = better for players. Reference points: live blackjack 0.5% house edge (excellent), roulette 2.7% (European), most slots 3-5%, crash games 1-3%, instant games 2.5-3%, game shows 3-4%. Side bets almost always have higher house edge than main games.

Volatility (Variance)

#

The measure of how risky or smooth a slot's payout pattern is over time.

Low volatility = frequent small wins, minimal bankroll swings, suitable for extended play on limited budget. Medium volatility = balanced hit frequency and payout sizes. High volatility = infrequent but larger wins, long dry spells punctuated by occasional big hits. Extreme/Very High volatility = rare but massive payouts, requires larger bankroll to survive the dry spells. Pragmatic Play's highest-volatility slots include Zeus vs Hades, Sugar Rush 1000, Starlight Princess 1000.

Variance

#

Statistical term for the spread of outcomes around the average. Often used interchangeably with volatility.

Technically: variance = average of squared deviations from the mean. Standard deviation = square root of variance. In slots context, higher variance means wider distribution of session outcomes — some big wins, many smaller losses, with dramatic bankroll swings. See also: variance compression — a concept we coined in our Bonus Buy explainer where buying bonuses concentrates the same underlying variance into shorter time periods.

Hit Frequency

#

How often a slot produces any winning combination on a single spin.

Expressed as percentage or ratio — e.g., 25% hit frequency means 1 in 4 spins produces some win (however small). Separate metric from RTP: a game can have high hit frequency with low average win size (producing high RTP through frequent small wins), or low hit frequency with massive occasional wins (same RTP, different feel). Hit frequency directly affects session experience. Pragmatic Play's tumble-mechanic slots (Sweet Bonanza, Gates of Olympus) have effective hit frequencies amplified by cascade wins.

Max Win (Maximum Win)

#

The largest possible payout the game can produce, expressed as a multiplier of your bet.

Also called 'max payout' or 'win cap.' Pragmatic Play max wins range dramatically: Tomb of the Scarab Queen 2,000× (low), Wolf Gold ~5,000× (mid), Zeus vs Hades 50,000× (very high), Peking Luck 180,000× (highest in catalogue). Max wins are capped — once you hit the ceiling, the game stops adding winnings even if math would suggest more. Critically: hitting max win is LOTTERY-TIER probability. Realistic sessions never approach it. Treat max wins as marketing language for the system ceiling, not expected outcomes.

Binomial Distribution

#

The probability model describing outcomes of independent yes/no trials — foundation of Plinko math.

Each of n independent trials has probability p of 'success' (e.g., ball going right at a peg). Binomial distribution tells you the probability of getting exactly k successes. In Plinko, each row's peg is a 50/50 independent trial, and the final pocket is determined by the cumulative left/right path. Relates to Pascal's Triangle — the Nth row gives you the relative probability distribution of ball landing in each pocket after N rows. Understanding this explains why Plinko's center pockets are high-probability but low-multiplier, while edge pockets are low-probability but high-multiplier.

Hypergeometric Distribution

#

Probability model for drawing without replacement from a finite population — foundation of Mines+ math.

Unlike binomial (trials are independent), hypergeometric models situations where each 'draw' depletes the pool. In Mines+, a 5×5 grid has 25 tiles with N mines placed before the round. Each tile click removes one tile from the remaining pool. Probability of next tile being safe = (remaining safe tiles) / (remaining total tiles). This means probabilities shift slightly with each successful click — fundamentally different from Plinko's independent coin flips.

Exponential Decay

#

Mathematical model describing probability curves where each additional unit is progressively less likely — foundation of crash game math.

In Spaceman and other crash games, the probability of the multiplier reaching value X decays exponentially. P(crash at X) ≈ (1 - house_edge) / X². This means the 2× multiplier is reached ~50% of the time, the 5× roughly 19%, the 10× roughly 9%, the 100× about 1%, and the 1,000× essentially lottery. The exponential curve is what makes crash games feel like 'just one more second' — each additional multiplier feels close but is actually exponentially less likely.

Pascal's Triangle

#

The geometric representation of binomial coefficients — visualizes Plinko probabilities perfectly.

Named after 17th-century mathematician Blaise Pascal. Each row starts and ends with 1, and every inner number is the sum of the two numbers above it. Row N gives you the coefficients (C(N,0), C(N,1), ..., C(N,N)) — which equal the relative probability of a Plinko ball landing in each pocket after N rows of pegs. An 8-row Plinko has 9 pockets, and their relative probabilities follow row 8 of Pascal's Triangle: 1, 8, 28, 56, 70, 56, 28, 8, 1 (total 256). The center pocket is 70/256 = 27.3% likely; the edge pockets are 1/256 = 0.4% each.

Slot Mechanics

Paylines, scatter pays, cluster pays, Megaways, Tumble, Hold & Spin, Money Collect, wild variants, bonus rounds, retriggering, and the '1000 Series'.

20 terms

Paylines

#

Predetermined patterns across reels where matching symbols form winning combinations.

Classic slot feature dating to mechanical machines. Modern slots range from 1 to 243+ paylines. Pragmatic Play's older titles (Wolf Gold, Big Bass Bonanza) use traditional paylines. Newer flagship titles have largely abandoned paylines in favor of scatter pays, cluster pays, or Megaways engines. Critical distinction: more paylines doesn't mean better odds — the RTP is fixed regardless of payline count. Paylines affect how wins are calculated, not whether you win.

Ways to Win

#

Alternative to paylines — any adjacent matching symbols from leftmost reel create wins.

Typical 5-reel slot with 3 rows = 243 ways to win (3×3×3×3×3). Simpler for players than counting paylines but functionally similar math. Games like Wolf Gold use 25-payline format while Dog House Megaways uses variable ways-to-win (up to 117,649). Ways-to-win is NOT the same as Megaways — it's a fixed count, while Megaways dynamically changes each spin.

Scatter Pays (Pay Anywhere)

#

Payout system where matching symbols anywhere on the grid form wins, regardless of position.

Introduced heavily by Pragmatic Play with Gates of Olympus. Typically requires 8+ matching symbols anywhere on a 6×5 grid to trigger a win. Removes all payline complexity — you just need enough of the same symbol on screen. Makes Tumble mechanic particularly effective (each cascade can trigger additional scatter-pay wins). Sweet Bonanza, Gates of Olympus, Starlight Princess, and the entire '1000 Series' use scatter pays.

Cluster Pays

#

Payout system where groups of 5+ connected matching symbols form winning clusters.

Sugar Rush, Sugar Rush 1000, Fruit Party all use cluster pays on 7×7 grids. Symbols must be adjacent (horizontal or vertical, not diagonal) to form a cluster. Larger clusters = bigger payouts. Works particularly well with tumble mechanic since exploded clusters create vacancies for new symbols to potentially form additional clusters.

Megaways

#

Dynamic reel engine where each reel has a variable number of symbols (2-7), creating up to 117,649+ ways to win per spin.

Licensed from Big Time Gaming by many studios including Pragmatic Play. The Dog House Megaways, Buffalo King Megaways (up to 200,704 ways), Great Rhino Megaways all use this engine. Each spin randomly generates reel heights, so the number of ways-to-win changes spin-to-spin. Typically combined with Tumble mechanic and enhanced wild features in free spins. High hit frequency due to massive ways-to-win counts.

Tumble / Cascade / Avalanche

#

Mechanic where winning symbols are removed and replaced with new ones, potentially creating chain reactions.

Three names for the same concept (different studios prefer different terms). After a win, the winning symbols 'tumble' off the grid, remaining symbols fall down, and new symbols drop in from above. If the new arrangement produces another win, the process repeats. Pragmatic Play's signature mechanic in Gates of Olympus, Sweet Bonanza, Sugar Rush, Fruit Party. Enables single spins to potentially produce chains of 10+ consecutive wins.

Hold & Spin (Hold & Win)

#

Bonus feature where special symbols lock in place and trigger respins, often with jackpot prizes.

Pioneered by slot studio Kalamba, heavily used by Pragmatic Play and competitors. Typically triggered by 6+ 'money' or 'coin' symbols landing simultaneously. Those symbols lock, player gets 3 respins, each new money symbol resets the respin counter to 3 and locks. Respins end when no new money symbols land. Total collected values paid out, often with jackpot tiers (Mini, Minor, Major, Grand). Wolf Gold uses this format for its Grand Jackpot mechanic.

Money Collect

#

Mechanic where special 'money' symbols accumulate values, then a 'collector' symbol sweeps them all up.

Different from Hold & Spin — instead of triggering a respin phase, Money Collect waits for a specific trigger symbol to appear. When the trigger lands, all visible money symbols' values are added together and paid out. Big Bass series uses fisherman as collector. Piggy Bankers uses piggy bank as collector. Tomb of the Scarab Queen also uses this pattern. Creates tension because money symbols are worthless until the collector arrives.

Wild Symbol

#

Symbol that substitutes for other symbols to complete winning combinations (usually excluding scatters).

Originally from physical slot machines. Modern variants: Expanding Wilds (grow to cover entire reel), Sticky Wilds (stay in place across multiple spins), Walking Wilds (move one position each spin), Multiplier Wilds (apply multipliers to wins they're part of). Pragmatic Play's Zeus vs Hades features Expanding Wilds with 100× multipliers in free spins — the main source of the game's 50,000× max win potential.

Scatter Symbol

#

Symbol that pays out regardless of position and typically triggers bonus rounds when enough land.

Different from 'scatter pays' (which is a payout mechanism). A scatter SYMBOL is typically used to trigger Free Spins — usually 3, 4, 5, or 6 scatters landing triggers the bonus with escalating free spin counts. In Gates of Olympus, 4 Zeus scatters = 15 free spins. Scatter symbols in modern slots often have higher-than-average appearance rates on specific reels (not truly random — game math is calibrated to trigger bonuses at target frequencies).

Expanding Wilds

#

Wild symbols that expand to cover entire reels when they land, dramatically increasing win potential.

Tomb of the Scarab Queen uses expanding wilds in free spins where they can fill whole reels. Zeus vs Hades has expanding wilds with multiplier values attached (2×, 3×, 5×, 10×, 50×, 100×). When the wild expands, the multiplier applies to all wins crossing that reel. Stacking multiple expanding wilds in one spin can produce spectacular outcomes.

Sticky Wilds

#

Wild symbols that remain in place across multiple subsequent spins, especially in free spins.

Dog House Megaways Sticky Wilds Free Spins mode: any wild that lands stays on the reel for the entire bonus round. Accumulating multiple sticky wilds guarantees them appearing on every remaining free spin, creating compounding win potential. Most impactful in longer bonus rounds where sticky count accumulates.

Multiplier Wilds

#

Wilds that carry a multiplier value applied to wins they contribute to.

Dog House Megaways wilds carry 2× or 3× multipliers. If two wilds contribute to the same win, their multipliers STACK multiplicatively — 2× × 3× = 6× win. Zeus vs Hades amplifies this dramatically with multipliers up to 100× per wild. Single free spin with multiple multiplier wilds can produce the 50,000× max win scenarios.

Multiplier Bombs (Rainbow Bombs)

#

Sweet Bonanza's signature feature — bomb symbols in free spins carrying multiplier values up to 100×.

During Sweet Bonanza free spins, rainbow bombs randomly land on the grid with multiplier values (2×, 3×, 4×, 5×, 6×, 8×, 10×, 12×, 15×, 20×, 25×, 50×, 100×). At the end of each tumble sequence, ALL bomb multipliers on the grid are added together and applied to the total win. Multiple 100× bombs in a single sequence can produce astronomical results — this is where Sweet Bonanza's 21,175× max win materializes.

Free Spins

#

Bonus round awarding additional spins at no extra cost, typically with enhanced mechanics.

Most Pragmatic Play slot bonus rounds are free spins with specific enhancements: multiplier stacking (Gates of Olympus), rainbow bomb multipliers (Sweet Bonanza), sticky wilds (Dog House Megaways), guaranteed high symbols (John Hunter series). Free spins typically contain 50-70% of a slot's total RTP — why bonus buys are priced to provide direct access to this portion of the game's value.

Respins

#

Limited additional spins triggered by specific conditions, often with locked symbols from the trigger spin.

Wolf Gold Money Respin: 3 moon symbols trigger 3 respins where money symbols lock and new money symbols reset counter. Different from Free Spins because respins typically maintain trigger state rather than starting fresh. Cheaper to trigger but smaller prize potential on average.

Bonus Round

#

Generic term for any enhanced game mode triggered during base play, usually containing the game's main prize potential.

Umbrella term covering Free Spins, Respins, Pick Bonuses, Hold & Spin, Wheel Bonuses, etc. Most Pragmatic Play bonus rounds contain 50-70% of the game's total RTP — dry base game is typical, action concentrated in bonus rounds. This is WHY bonus buys exist as a commercial product — players want direct bonus access.

Super Scatter

#

Enhanced scatter mechanic in newer Pragmatic Play slots (Gates of Olympus Super Scatter, Sweet Bonanza Super Scatter, etc.)

Introduced 2024-2025 as an evolution of the scatter-pays system. Super Scatter mechanic adds an additional premium scatter tier that pays higher than regular scatters and triggers enhanced bonus rounds. Available in Gates of Olympus Super Scatter, Sweet Bonanza Super Scatter, Starlight Princess Super Scatter. Often combined with new multiplier systems in the free spins round.

Retrigger

#

Landing scatter symbols during an active bonus round to extend or reset the bonus duration.

Gates of Olympus free spins: 3+ scatters during bonus = +5 free spins added to remaining. Big Bass Bonanza: retriggering during Free Spins increases the fisherman collection multiplier tier. Sweet Bonanza: 3 scatters during free spins = +5 free spins. Retriggers are essential to pursuing max win scenarios — a single bonus round must usually extend through multiple retriggers to reach ceiling payouts.

The 1000 Series

#

Pragmatic Play's 2023+ line of supercharged versions of flagship slots with dramatically increased multiplier ceilings.

Starlight Princess 1000 (first, 2023), Sugar Rush 1000, Gates of Olympus 1000, Big Bass Bonanza 1000, Sweet Bonanza 1000, Big Bass Splash 1000, Gates of Olympus Xmas 1000. Core concept: multiplier values up to 1000× (vs 500× in original versions). Max wins increased dramatically — typical jump from 5,000× to 25,000× or 15,000×. RTP maintained at 96.5% typically. Targets high-volatility players specifically.

Bonus Buy, Ante Bet, and Super Free Spins mechanics — with links to detailed math analysis.

3 terms

Bonus Buy (Feature Buy)

#

Feature that lets players pay a premium (typically 100× bet) to instantly trigger the main bonus round.

Introduced mainstream in 2018-2019. Pays typically 100× bet to access Free Spins directly, bypassing base game. BANNED in UK (September 2024) and Netherlands. See our dedicated explainer for full mathematics — including the counter-intuitive fact that bonus buy RTP is typically +0.2-0.5% HIGHER than base game, offset by variance compression concentrating risk ~17× per minute.

Ante Bet

#

Optional +25% bet premium that approximately doubles your natural bonus trigger frequency.

Available on select Pragmatic Play titles (Gates of Olympus, Starlight Princess, Sweet Bonanza, Sugar Rush original — NOT 1000 versions). RTP unchanged. For most recreational players, Ante Bet is mathematically superior to Bonus Buy — distributed bonus exposure, smoother bankroll, preserved base game entertainment.

Super Free Spins

#

Premium tier of bonus buy starting with enhanced conditions — usually higher multipliers already on grid.

Sugar Rush 1000 offers 500× bet Super Free Spins (vs 100× standard) — starts with 2× multipliers already on grid. Super FS has VERIFIED higher RTP (96.55% vs 96.52% standard buy, 96.53% base game) — genuine positive EV edge for disciplined players with adequate bankroll.

Basic Strategy

#

Mathematically-proven optimal decision for every blackjack hand-vs-dealer situation.

Published in 1956 by Baldwin, Cantey, Maisel, and McDermott. Shows when to Hit, Stand, Double, Split, or Surrender for every combination of player hand and dealer up-card. Using Basic Strategy reduces house edge to its mathematical minimum (~0.5% for Vegas rules). NOT actually secret or advantage play — it's just arithmetic applied. Basic Strategy cards are legal to reference at land casinos and permitted in all regulated live casino jurisdictions.

Card Counting

#

Tracking played cards to estimate favorable vs unfavorable remaining shoe composition.

Famous strategy from Ed Thorp's 1962 book 'Beat the Dealer.' Works by keeping running count of high cards (favorable to player) vs low cards (favorable to dealer). Modern live casino defenses: 8-deck shoes (dilutes edge), mid-shoe shuffles (resets count), RNG in burn cards. In online live casino, card counting is essentially unviable — the 8-deck shoe with mid-shoe shuffle means true counts rarely develop enough for profitable betting. See our Live Blackjack review for detailed math.

Soft 17 (S17 / H17)

#

Blackjack hand of 17 containing an Ace counted as 11. 'Stand on soft 17' (S17) vs 'Hit on soft 17' (H17) rules differ by table.

Pragmatic Play's live blackjack tables use S17 (dealer stands on soft 17) — the PLAYER-FAVORABLE rule. H17 (dealer hits soft 17) is common in Las Vegas physical casinos and adds ~0.22% to house edge. S17 is standard in European casinos and most online live blackjack. Check the rules panel of any specific table to verify.

DAS (Double After Split)

#

Blackjack rule allowing a player to double down on hands created by splitting a pair.

Pragmatic Play added DAS to all their live blackjack tables in JUNE 2025, raising RTP by ~0.13 percentage points across the lineup. ONE Blackjack: 99.41% → 99.54%. Classic 7-seat: 99.37% → 99.50%. Speed Blackjack: 99.46% → 99.59%. Most online sources still cite pre-June-2025 figures. Always verify current rules in-game.

Insurance (Blackjack)

#

Optional side bet offered when dealer shows an Ace, paying 2:1 if dealer has a 10-value hole card.

Mathematically disadvantageous in nearly all situations. Against a random 8-deck shoe, the dealer has ~30.8% probability of 10-value hole card. Insurance pays 2:1 on win, meaning you need >33.3% probability to break even. The 2.5 percentage point gap creates meaningful house edge (~7% on the insurance side bet). Basic Strategy: never take insurance unless you're actively counting cards AND the count is very high. Card counters had a niche use case historically, but useless in modern multi-deck online live play.

6 Card Charlie Rule

#

Blackjack bonus rule: reach 6 cards without busting = automatic win regardless of dealer's hand.

Unique to Pragmatic Play's ONE Blackjack table among their blackjack products. Reduces house edge by ~0.16 percentage points. Triggers approximately 1 in 125-175 hands. Strategic implication: 5-card hands with hard 12-16 become slightly more HIT-favorable because reaching 6 cards without busting wins regardless of dealer outcome. Basic Strategy charts for ONE Blackjack reflect this nuance.

One-to-Many Deal

#

Live blackjack format where one physical card deal serves unlimited simultaneous players.

Pioneered by Evolution Gaming's Infinite Blackjack (2017), adopted by Pragmatic Play's ONE Blackjack (March 2021) and Playtech's All Bets Blackjack. Technical mechanism: physical cards are dealt to a shared platform; each player's individual decisions (Hit, Split, Double) produce virtual cards visible only to that player. Unlimited players can participate in the same hand. Other players' decisions don't affect yours, and vice versa.

Bet Behind

#

Feature on 7-seat live blackjack allowing spectators to wager on an active player's hand.

Available on Pragmatic Play's classic 7-seat Live Blackjack tables. When all 7 seats are full, new players can Bet Behind — wager on another seat's outcome. Also allows seated players to scale exposure by betting behind other seats. NOT available on ONE Blackjack (unnecessary because unlimited seating). Some players find Bet Behind entertaining; others prefer direct decision-making.

Perfect Pairs (Side Bet)

#

Blackjack side bet paying when your first two cards form a pair, with higher payouts for matching colors/suits.

Available on Pragmatic Play Live Blackjack and ONE Blackjack. Payout tiers: mixed-colour pair 6:1, same-colour 12:1, same-suit (perfect) 25:1. RTP 95.90% — 3.64 percentage points worse than main game (99.54%). Side bets in general have worse math than the main game.

21+3 (Side Bet)

#

Blackjack side bet based on your first two cards plus the dealer's up-card forming a 3-card poker hand.

Payouts: Straight 5:1, Flush 5:1, Three of a Kind 30:1, Straight Flush 40:1, Suited Three of a Kind 100:1. RTP 96.30% — the LEAST BAD side bet on Pragmatic Play blackjack tables but still worse than main game. Popular among recreational players who enjoy occasional multiplier hits.

Crazy 7 (Side Bet)

#

Unique ONE Blackjack side bet paying based on 7s appearing in your first 3 cards. Max payout 2,000:1 for three suited 7s.

Unique to Pragmatic Play's ONE Blackjack in live blackjack space. Payout tiers escalate from one 7 to three suited 7s (2,000:1 — the game's overall max payout). RTP 94.26%. Three suited 7s probability: approximately 1 in 133,000 hands — essentially lottery-tier.

Bust Bonus (Side Bet)

#

Blackjack side bet paying when the dealer busts. Payouts increase with number of cards in dealer's busted hand.

Available on ONE Blackjack. Payouts: 3-card bust 1:1, 4-card 2:1, 5-card 9:1, 6-card 50:1, 7-card 100:1, 8+ card 250:1. RTP 93.82% — WORST side bet on the table by ~5.72 percentage points vs main game. Despite the 250:1 headline payout, multi-card busts are extraordinarily rare (1 in 10,000+ dealer hands).

Side Bet

#

Optional wager made alongside the main bet, typically with different (usually worse) RTP.

Present on most live casino games. Almost always have WORSE RTP than main game. Pragmatic Play side bet RTPs: Perfect Pairs 95.90%, 21+3 96.30%, Crazy 7 94.26%, Bust Bonus 93.82%. Main blackjack game: 99.54%. Side bets are marketing-driven additions, not strategic enhancements. Over 1,000 hands at €10 each with €2 side bets, Bust Bonus loses approximately 13× more money than the main bet.

Mega Lucky Number

#

Mega Wheel's signature mechanic — pre-spin RNG assigns a random multiplier to one wheel segment.

Pragmatic Play's innovation over Evolution Gaming's Dream Catcher (2017 original). Before each wheel spin, RNG randomly selects ONE number and assigns a multiplier (1× to 500×). If the wheel lands on that specific number, the multiplier applies to the base payout. Visible BEFORE the spin (vs Dream Catcher's post-spin multiplier application), creating extended anticipation during the wheel rotation.

Mega Multiplier

#

Umbrella term for Pragmatic Play's 'Mega' series pre-spin multiplier feature (Mega Roulette, Mega Sic Bo, Mega Wheel).

Family of live game shows using similar mechanic: RNG-assigned multiplier before each spin/roll. Mega Roulette: straight-up number bets can receive 50×-500× multipliers. Mega Sic Bo: dice roll outcomes receive up to 5,000× multipliers. Mega Wheel: 500× max on rarest numbers.

Crash Point

#

The multiplier value at which a crash game round ends, determined pre-round by RNG.

In Spaceman and similar crash games, the crash point is generated before the round begins using RNG (or provably fair cryptographic seeding). The multiplier starts at 1× and climbs until it reaches this predetermined crash point, at which moment the game ends. Players must cash out BEFORE the crash to win. Crash point distribution follows exponential decay — most rounds crash early, rare ones reach massive multipliers.

Cashout

#

The player action of securing winnings before a crash game round ends.

Core mechanic of crash games. Click 'Cashout' button before the multiplier crashes = win bet × current multiplier. Miss the cashout = lose entire bet. Auto-cashout feature allows pre-setting a target multiplier for automatic exit. Spaceman's unique 50% Cashout feature lets you bank half your winnings while the other half rides — half-exit strategy unavailable in most crash games.

50% Cashout

#

Spaceman's signature mechanic — cash out HALF of your bet amount while keeping the other half riding the multiplier.

Unique feature among crash games. Allows risk management impossible in standard crash — bank guaranteed winnings (current multiplier × 50% of bet) while still having exposure if the multiplier continues climbing. Useful strategic tool but doesn't change overall RTP — the half you cashed out captured its EV, the half riding still has the same crash probability distribution.

Auto-Cashout

#

Pre-set target multiplier for automatic cashout, useful for consistent strategy execution.

Set a target (e.g., 1.5×, 2×, 3×, 10×) and the game automatically cashes out when the multiplier reaches that value. Removes emotional decision-making and enables mathematical strategies (like targeting 2× at ~50% hit rate). Most crash games support auto-cashout. Important: auto-cashout doesn't beat the house edge — it just reduces decision stress.

Provably Fair

#

Cryptographic verification system allowing players to independently confirm each round's outcome was generated fairly.

Uses SHA-256 or similar hashing with server seed + client seed combination. Each round's outcome is deterministic based on these seeds, but the server seed is committed (hashed) before the round, then revealed after — meaning the server couldn't have manipulated the outcome after seeing your bet. Standard in crypto-casino games (Spribe Aviator, Stake Originals, BGaming). Less common in regulated-operator games (Pragmatic Play's Plinko+ and Mines+ use certified RNG without prominently advertising Provably Fair). For players valuing per-round verification, look for the 'Provably Fair' badge on game info panels.

RNG (Random Number Generator)

#

Computer algorithm producing sequences of numbers without pattern — foundation of all digital casino games.

Every digital casino game uses RNG to determine outcomes. Modern regulated RNGs are 'pseudo-random' — deterministic algorithms that produce sequences so long and complex they appear random. Third-party testing labs (GLI, BMM, iTech Labs) certify RNG implementations. Regulated markets require periodic RNG audits. Good RNG implementation is effectively indistinguishable from true randomness for gambling purposes. See Provably Fair for per-round verification mechanism (different from certified RNG which is audited in aggregate).

UKGC (UK Gambling Commission)

#

UK regulator controlling licensed online casino operations in Great Britain.

Most restrictive major regulated market. Imposes strict consumer protection rules: affordability checks, deposit limits, advertising restrictions, banned bonus buys (September 2024), banned high-volatility features, reality-check timers. UK-licensed operators (Bet365, Coral, Sky Vegas, 888) must follow all UKGC rules. Pragmatic Play games on UK operators are typically reduced-feature versions of the international products.

MGA (Malta Gaming Authority)

#

Malta-based regulator licensing operators across multiple European markets.

One of the oldest and most respected EU iGaming regulators. MGA-licensed operators can serve customers in many European countries. More flexible than UKGC — bonus buys permitted, wider bonus promotions allowed. Pragmatic Play's corporate headquarters is in Malta. MGA license is prerequisite for many European operator brands.

AGCO (Alcohol and Gaming Commission of Ontario)

#

Ontario, Canada regulator operating since April 2022.

North America's largest regulated iGaming market. 50+ licensed operators in Ontario. Relatively open regulatory regime compared to UKGC — bonus buys permitted, minimal advertising restrictions, adults 19+ can participate. Pragmatic Play well-represented across Ontario operators.

GGL (Gemeinsame Glücksspielbehörde der Länder)

#

German federal iGaming regulator with highly restrictive rules including €1 maximum bet per spin.

Germany's regulated online casino framework effective since 2021. Most restrictive major European market. €1 maximum spin bet caps high-roller play. 5-second mandatory delay between spins (no rapid autoplay). No jackpot games. Bonus restrictions. Pragmatic Play slots on GGL-licensed sites are heavily modified vs international versions.

GLI (Gaming Laboratories International)

#

Independent third-party lab certifying RNG algorithms and game math for regulated iGaming.

Most widely-used iGaming testing lab globally. Certifies RTP claims, RNG randomness, game mechanic fairness for operators in 20+ jurisdictions. Pragmatic Play games carry GLI certifications. Their audits verify the math at launch and periodic re-audits ensure ongoing compliance. Other major labs: BMM Testlabs, iTech Labs, QUINEL.

Drops & Wins

#

Pragmatic Play's flagship ongoing network promotion with €25M+ annual prize pool.

Runs continuously since January 2020. Each 12-month edition distributes €25,000,000+ (UK: £11,760,000). Two mechanics: Daily Tournaments (364/year, leaderboard-based) and Weekly Wheel Drops (52/year, random piece collection). Zero wagering requirements on all prizes — unique among major casino promotions. Current edition: 4 March 2026 – 3 March 2027. Effective rebate for regular players: 0.3-0.6% of wagered volume.

Qualifying Bet

#

Minimum bet amount required for a spin to count toward promotion or bonus requirements.

Drops & Wins qualifying bet: £0.15/€0.15 minimum. Bets below this don't score toward tournament leaderboard or wheel piece collection. Also used in bonus wagering — bets below specific thresholds (usually €0.50 or €1) may not count toward wagering requirement progress. Always check specific promotion terms.

Wagering Requirement (Playthrough)

#

The amount you must bet before bonus funds or winnings from bonuses can be withdrawn.

Expressed as a multiplier of the bonus amount. 35× wagering on €100 bonus = €3,500 must be wagered before withdrawal permitted. Typical ranges: 25x-45x for deposit matches, 30x-60x for free spins winnings. Drops & Wins prizes carry ZERO wagering requirements — cash winnings are immediately withdrawable. This distinguishes Drops & Wins from most casino bonuses and is the promotion's strongest player-positive feature.

One reminder about terminology.

iGaming terminology evolves continuously. New mechanics arrive (Super Scatter in 2024, the '1000 Series' in 2023, Mega Lucky Number in 2020), regulations change (UK bonus buy ban September 2024, Pragmatic Play's DAS implementation June 2025), and marketing departments coin new branded terms regularly. We update this glossary periodically as meaningful changes happen but can't promise real-time synchronization with every Pragmatic Play release. If you encounter a term not defined here that you'd like explained, our FAQ library may cover it, or check the in-game info panel of the specific game — most Pragmatic Play slots include their own mechanic glossary in the rules screen.

A final caveat on the mathematical terms (binomial distribution, hypergeometric, exponential decay, Pascal's Triangle): these are ACTUAL probability concepts, not marketing approximations. If you want rigorous proofs rather than conceptual explanations, any undergraduate probability textbook (Ross, Grimmett & Stirzaker, Feller) covers them formally. Our definitions here focus on practical gambling context — sufficient for understanding how games work, insufficient for deriving the math from scratch.
