Every term you’ll meet in crash and instant games, defined plainly. Where a term is used misleadingly in marketing — and several are — that’s noted too.
Core Mechanics
Crash point — the multiplier at which a round ends. Generated before the round begins, not during it. This single fact is why predictor software cannot work.
Cash out — banking your bet at the current multiplier. Your payout is stake × multiplier at the moment you exit.
Auto cash-out — a preset multiplier at which the game exits for you. The single most useful control available, because it removes the decision from a moment of adrenaline.
Dual bet / multi-bet — placing two or more independent bets in the same round, each with its own stake and target. Aviator allows two, JetX three. It changes variance, not expected value.
Half cash-out — banking 50% of a position while the rest rides. Spaceman’s signature feature.
Instant game — the broader category covering crash titles plus grid and progression games like Mines and Dragon Tower. Rounds last seconds and there are no reels.
The Numbers
RTP (Return to Player) — the percentage of total wagers a game returns over millions of rounds. A 97% RTP means 97 units returned per 100 wagered in aggregate, not per session. It says nothing about your next hour.
House edge — the inverse: 100% minus RTP. At 97% RTP the edge is 3%. This is the operator’s mathematical revenue and no strategy removes it.
Volatility (variance) — how widely results swing around the average. High volatility means rare large wins and long dry spells; low volatility means frequent small results. Several games let you set it yourself.
Max multiplier — the ceiling a game can pay. Frequently quoted in marketing and almost never relevant: a 25,000x ceiling describes an outcome you will not see, while your median round ends near 2x.
Expected value (EV) — the average result of a bet if repeated indefinitely. In every game covered here it’s negative, by exactly the house edge.
Fairness and Verification
Provably fair — a cryptographic system letting you verify that a round’s outcome wasn’t altered. The server commits to a hashed seed before you bet and reveals it afterwards. Full explanation here.
Server seed — the casino’s secret random value, published as a hash before the round and revealed after.
Client seed — your contribution to the randomness, usually changeable. It’s what prevents the casino pre-selecting an outcome for you.
Certified RNG — random number generation audited by independent testing labs as a licence condition. Legitimate, but verified institutionally rather than by you personally.
Hash — a one-way cryptographic fingerprint. Publishing one commits to a value without revealing it, and it can’t be forged afterwards.
Money and Accounts
Wagering requirement (playthrough) — how many times a bonus must be wagered before withdrawal. A “100% up to $500” bonus with 40x wagering requires $20,000 in bets before the money is yours. Always read this number first.
Rakeback — a percentage of wagers returned regardless of outcome. Genuine value, though it also rewards volume, which is the point.
KYC (Know Your Customer) — identity verification required before withdrawal at licensed operators. In South Africa this is FICA. Complete it at registration rather than discovering it when you’ve won.
Rain — free bets dropped into a game’s chat at random intervals, claimable by anyone watching. Real value, and also a mechanism that rewards staying logged in.
Terms Used Misleadingly
Predictor — software claiming to forecast crash points. Cannot exist, because outcomes are committed before rounds begin. What these products actually do is documented in our breakdown.
Signal — a paid tip on when to cash out. Same impossibility, sold by subscription instead of download.
Hack / mod APK — usually malware, frequently requesting SMS permissions that no game needs.
“Due” / “hot” / “cold” — gambler’s fallacy dressed as insight. Rounds are independent; nothing is ever due.
Guaranteed strategy — a contradiction in terms where the house edge is fixed. See our strategy analysis for what systems actually do.
Responsible Play
Deposit limit — a cap you set on funding, enforced by the operator. Increases usually carry a cooling-off delay by design.
Loss limit — a hard stop the platform enforces even when you’d rather continue.
Self-exclusion — blocking your own access for a fixed period or permanently. GAMSTOP covers all UK-licensed operators at once; South Africa runs it through provincial boards. See our responsible gambling page.
Chasing losses — increasing stakes to recover a deficit. The single most reliable way to turn a small loss into a large one.
