This is a plain-English reference to 65 or more crash-game terms across mechanics, fairness, formats, strategy and regulation, each linked to the guide that covers it in depth. One rule governs the fairness half: provably fair proves honesty, not generosity. It can show a result was not altered; it never removes the house edge.
Use it as a reference: scan to a term, read the one-line definition, and follow the link when you want the full treatment. Where a misconception commonly attaches to a term, it is flagged in italics underneath.
⚠️ Start here: three myths to drop
Before the definitions, three corrections that the rest of the glossary keeps reinforcing. Each is a phrase players routinely misread.
Several terms below touch the psychology of harm, near-misses, loss-chasing, the gambler’s fallacy. We cover the research evidence, the risk factors and what regulators are doing in a dedicated guide: crash gambling and player harm.
🔍 Crash game terms, A to Z
Every significant crash term, defined in plain English, with a link to the page that covers it in depth where one exists.
A
Aggregate fairness. Fairness shown across many rounds through a published RTP and certification, rather than proof of any single round. Certified-RNG games rely on this; provably-fair games add per-round proof on top.
Aggregator. A platform that bundles many studios’ games into one integration, so a casino can offer them without contracting each studio directly.
Anjouan. A gaming licence from the Comoros, increasingly used by crypto casinos after Curacao’s reforms. It is lighter-touch than the MGA or UKGC, with limited player recourse.
Anti-Martingale. A positive progression that raises stakes after wins and cuts them after losses, the mirror of the Martingale. It changes variance, never expected value. See the Anti-Martingale guide. Misconception: it does not make a losing game profitable.
Auto-bet. A setting that places a run of bets automatically to fixed rules, often with stop-on-profit or stop-on-loss triggers. It speeds play up, which increases how much edge you pay per hour.
Auto-cashout. A pre-set multiplier at which the game cashes you out automatically, removing reaction time and latency risk. Misconception: it does not change the house edge; it only fixes your target.
B
B2B supplier. A studio that builds games and licenses them to casinos rather than running a casino itself. Spribe, BGaming and Evolution are B2B suppliers.
Bankroll. The total money set aside for play. Sound practice splits it into per-session amounts with fixed limits. See bankroll management.
Binding property. The cryptographic guarantee that a committed value cannot later be changed. In provably fair, it stops a casino altering a result after you have bet.
Bitcoin-block salt. Extra randomness taken from a future Bitcoin block hash and mixed into a pre-generated result chain, proving the operator could not have selected a favourable seed. Bustabit’s use of this is a transparency benchmark.
BMM Testlabs. An independent laboratory that tests and certifies RNGs and game fairness for regulators worldwide.
Bust (crash). The moment the multiplier stops climbing and the round ends. Any bet not already cashed out is lost.
C
Cash-out. Collecting your bet at the current multiplier before the round busts. Your payout is your stake times the multiplier at that instant.
Certified RNG. A random number generator independently tested and certified, by labs such as eCOGRA or iTech Labs, but without per-round cryptographic proof. Fairness rests on the certificate and the licence, not on maths you can check yourself. Provably fair proves honesty round by round; certified RNG proves it in aggregate.
Client seed. A random input from the player’s browser, or typed by the player, that combines with the server seed to generate a result, so the casino cannot predict the outcome alone.
Collision resistance. The property of a hash function that makes it practically impossible to find two inputs with the same output, which is what makes a published hash a trustworthy commitment.
Commit-reveal scheme. The two-step process behind provably fair: the casino publishes a hash of the server seed before the round (commit), then reveals the seed afterwards (reveal) so you can recompute and check the result.
Crash game. A casino format built around a single decision: cash out before a rising multiplier crashes at a randomly determined point. See what crash gambling is.
Crash point. The multiplier at which a round ends. On provably-fair games it is determined before the round starts, not in response to your bet.
Curacao. A long-standing offshore gaming jurisdiction. Its 2024 LOK reform, adopted 17 December 2024 and in force 24 December 2024, restructured licensing and prompted some operators to move to Anjouan.
D
Dual bet. Placing two independent bets in the same round, each with its own cash-out target, common in Aviator. It splits risk across two outcomes; it does not change expected value. See the Aviator guide.
E
eCOGRA. An independent testing and certification body for online gaming fairness and RNGs.
Expected value (EV). The average outcome of a bet over the long run. On every crash game it is negative, equal to minus the house edge times your stake, at every cash-out target. See the crash gambling maths. Misconception: no cash-out target, system or streak makes EV positive.
F
Fibonacci. A negative progression that sizes stakes along the Fibonacci sequence after losses. Like every staking system, it reshuffles variance without touching the house edge.
Flat betting. Staking the same amount every round. It is the lowest-variance approach and the easiest to budget, though it still loses the edge over time. See flat betting.
G
Gambler’s fallacy. The mistaken belief that past results make a future result “due”, such as expecting a high multiplier because several low ones just landed. Each round is independent. See crash game patterns.
Game show (live crash). A live-dealer, crash-style format hosted on camera, the best-known being Evolution’s Cash or Crash Live, released 22 September 2021. These cannot be provably fair, because outcomes come from a physical draw, so trust rests on regulation and audit. See the Evolution profile.
GAMSTOP. The UK’s national self-exclusion scheme. Players can exclude for 6 months, 1 year or 5 years, with a “5 years with auto-renewal” option added in December 2024.
GLI (Gaming Laboratories International). A major testing and certification lab. It acquired iTech Labs on 19 May 2023.
H
Hash chain. A long sequence of hashes generated in advance, each linked to the next, so results are fixed before any bet is placed. BC.Game and Bustabit use multi-million-link chains.
Hash function. A one-way mathematical function that turns any input into a fixed-length output that cannot be reversed, the building block of provably fair.
HMAC-SHA256. A keyed hashing method used by Stake and others to generate provably-fair results from the server seed, client seed and nonce.
Hot-hand fallacy. The belief that a winning streak will continue because you are “running hot”. Streaks are variance, not momentum.
House edge. The casino’s mathematical margin, the complement of RTP. A 97% RTP is a 3% house edge, applied mechanically through the instant-crash chance.
House original. A game built and run by the casino itself rather than supplied by a third-party studio. Most crypto crash games, including Stake, BC.Game and Bustabit, are house originals.
I
Instant crash (1.00x). A round that busts immediately at 1.00x, losing all uncashed bets. Its frequency roughly equals the house edge, about 1 round in 100 on a 99% game and about 3 in 100 on a 97% game. This is how the edge is applied.
Instant game. A fast, single-decision game such as crash, Plinko, Mines or Limbo that resolves in seconds, as opposed to slots or table games.
iTech Labs. An independent RNG and game-fairness testing laboratory, acquired by GLI in May 2023.
L
Limbo. An instant game where you set a target multiplier and the round either meets it or does not, with no rising curve. See the Limbo guide.
Loss-chasing. Raising stakes or extending a session to recover losses. It is the single most dangerous betting pattern and sharply raises the risk of ruin. See session management.
Loss limit. A pre-set amount you will not lose past in a session, the strongest practical bankroll control.
M
Martingale. A negative progression that doubles the stake after each loss to recover it on the next win. It cannot beat the edge and risks catastrophic loss against table limits and a finite bankroll. See the Martingale guide.
MGA (Malta Gaming Authority). A respected European regulator. An MGA licence carries meaningful player protections and a dispute-resolution route.
Mines. A grid game where you reveal tiles while avoiding hidden mines, cashing out before you hit one. See the Mines guide.
Multiplier. The number, starting at 1.00x and rising, by which a winning bet is paid. Your payout is stake times the multiplier at cash-out.
N
Near-miss. An outcome that lands just short of a win, such as a crash a fraction below your target. In crash games the near-miss is the format itself, not bad luck, and it is a known driver of continued play.
Nonce. A counter that increments with each bet, so the same seed pair produces a fresh result every round.
O
Operator-configurable RTP. An RTP the casino can set from a range the studio supplies, so the same game can pay differently at different casinos. JetX runs 96.2% to 98.9% by operator setting; always read the in-game info panel. See the JetX guide. Aviator’s RTP, by contrast, is a fixed 97% by default; secondary sources claim operators can run 96% or 94%, but no Spribe certification document confirms it.
P
Per-round verification. The ability to cryptographically check a single round’s result, the defining feature of provably fair and the thing certified-RNG games lack.
Plinko. A game where a ball drops through pegs into multiplier slots, its landing following a binomial distribution. See the Plinko guide.
Provably fair. A system that lets you cryptographically verify each result was not altered after you bet, using a committed server seed, your client seed and a nonce. See provably fair explained. Misconception: it proves honesty, not generosity; it does not remove or reduce the house edge.
R
RTP (return to player). The percentage of all wagered money a game returns to players over time. A 97% RTP returns $97 of every $100 staked in aggregate; the rest is the house edge. Misconception: a higher RTP lowers your long-run cost but guarantees nothing in any single session.
S
Self-exclusion. A formal request to bar yourself from gambling for a set period, enforced by the operator or a scheme such as GAMSTOP. Hard locks work better than soft reminders.
Server seed. A random value the casino generates and commits to, as a published hash, before a round, then reveals afterwards so you can verify the result.
Session bankroll. The slice of your total bankroll allocated to a single session, ring-fenced with its own loss limit and win target. See the beginner strategy guide.
SHA-256. A cryptographic hash function widely used for server-seed commitments and hash chains in provably-fair systems.
SHA-512. A larger hash function in the same family, used by some games, including Spribe’s titles and Aviator, to generate the round result while SHA-256 handles the commitment.
Stake sizing. How much of your bankroll you risk per round, commonly 1% to 2% flat or a small fixed percentage. Smaller stakes lengthen play and reduce ruin risk.
Sunk-cost fallacy. Continuing to bet because of what you have already lost, as though past losses could be recovered by playing on. They cannot; each round stands alone.
T
Terminating hash. The final, published hash of a pre-generated result chain, proving every outcome existed before any bet. Bustabit publishes one; some chains, including BC.Game’s Crash and Gamdom’s Crash, do not.
Third-party game. A game supplied by an external studio rather than built by the casino, for example Spribe’s Aviator running on a licensed operator.
U
UKGC (UK Gambling Commission). Britain’s regulator, among the strictest, requiring deposit limits, GAMSTOP integration, audited fairness and segregated player funds.
V
Volatility. How widely results swing around the average. Risk levels and cash-out targets change volatility, not expected value: high volatility means rarer, larger wins.
W
Win target. A pre-set profit level at which you stop a session. Paired with a loss limit, it is a core pre-commitment tool.
