Crash Game Rules: The 4 Phases of a Round Explained Step by Step (2026)
Crash game rules fit in four phases per round: pre-bet (input stake), bet close (cryptographic commit), multiplier rise (player decides cashout timing), and round end (resolve win or loss). The whole sequence runs in 12-30 seconds. Learning the rules takes 5 minutes; learning to execute them with discipline takes 100 rounds. This piece walks through each phase in operational detail, plus auto-cashout configuration, Dual Bet on Aviator, what happens when you fail to cash out in time, and what is explicitly NOT in the rules.
- One crash round runs through 4 phases: Phase 1 pre-bet (input stake plus optional auto-cashout target, ~5-10 seconds), Phase 2 bet close (casino commits SHA hash of server seed pre-round), Phase 3 multiplier rise (player decides cashout timing, 12-25 seconds typically), Phase 4 round end (resolve win or full stake loss; reveal seed for verification).
- Cashout timing is the only decision a player makes within a round. Click the cashout button at any time during multiplier rise to lock the current multiplier as your win (winnings = stake × cashout multiplier). Set auto-cashout pre-round to execute automatically at a target multiplier. If neither cashout fires before the multiplier crashes, full stake is lost.
- Auto-cashout configuration is the recommended discipline tool. Type a target multiplier (e.g., 1.8) in the auto field, toggle the auto switch on. The engine locks the cashout at exactly that multiplier when reached. Removes 200-300ms reaction-time noise plus emotional mid-round decisions. For coverage of auto-cashout strategy, see our auto-cashout strategy piece.
- If you miss the cashout window, the stake is lost. There is no recovery mechanism. No "freeze the round" feature; no "pull back the bet" option; no "cashout slightly late" partial credit. The round is binary at the cashout decision. Marketing claims that suggest otherwise ("you can recover any loss") are misleading. The only recovery is bankroll discipline and disciplined session limits.
- Dual Bet on Aviator is the only major rule variant. Aviator's panel shows two bet boxes side by side, each with independent stake and auto-cashout target. Both run in parallel within the same round; both can win, both can lose, or one can win and the other lose. The asymmetric setup that works: 70% of total round stake at 1.4x grind plus 30% at 5x lottery (both on auto-cashout).
The rules of every crash game
New to crash and need the basic rules? Crash games are simple in mechanics, deep in math. The rules fit on one page. Here they are.
Bottom line
One crash round runs through 4 phases: Phase 1 pre-bet (input stake plus optional auto-cashout target, ~5-10 seconds), Phase 2 bet close (casino commits SHA hash of server seed pre-round), Phase 3 multiplier rise (player decides cashout timing, 12-25 seconds typically), Phase 4 round end (resolve win or full stake loss; reveal seed for verification). Cashout timing is the only decision a player makes within a round. Click the cashout button at any time during the rise to lock the current multiplier into your win.
1. You place a bet before the round starts. Bet amount is your choice within the operator's range.
2. The round starts. A multiplier counter starts at 1.00x and climbs upward over time. Speed varies by game.
3. At any point during the round, you can hit Cash Out. Your stake gets multiplied by the current multiplier and paid out.
4. The round eventually crashes - the multiplier counter stops at a random point determined by the game's RNG. If you did not cash out before the crash, you lose your stake.
That is it. Five lines.
The features that vary between titles
Curious what makes one crash game different from another? Mostly four things.
Auto-cashout. Pre-set a target multiplier. Game cashes out automatically when reached. Universal across all modern crash.
Dual Bet. Two parallel bets per round, each with its own auto-cashout. Aviator pioneered this; most newer games copy it.
Partial cashout. Lock half your stake mid-round, ride the other half. Spaceman is the only licensed crash with this feature.
Provably fair scheme. SHA-256 or SHA-512, one client seed or multiple. Determines whether you can verify rounds yourself.
"Crash games have five rules and unlimited variance. The simplicity is part of why the format scales - you can teach the rules in 30 seconds, but the actual play takes years to internalize."
What you cannot do
Three common misconceptions to clear up:
You cannot predict the crash point. The math (SHA hashing) is cryptographically random. Anyone selling predictors is selling scams.
You cannot exploit patterns. Each round is independent. Past rounds give zero information about future rounds.
You cannot beat the house edge. 3% on most aviation crash, 1% on Cash or Crash Live, 0.41% on the highest-RTP titles. No strategy makes the edge smaller.
Standard parameters across crash titles
Most crash games share these parameters:
Min bet: $0.10 typical (some at $1).
Max bet: $100 typical (some up to $500).
RTP: 96-97% typical (range 95-99.59% across catalog).
Round time: 4-30 seconds for aviation crash, 60-90 seconds for live-format.
House edge: 3% on most games, lower on premium-RTP titles.
What to do before your first crash session
Three pre-flight checks:
1. Check the in-game RTP panel. Confirm what your operator actually ships. Operators can configure below studio default.
2. Set an auto-cashout target. Pick 1.5x, 2x, or 5x based on the variance you want.
3. Set a session bankroll cap. Decide your stop-loss before you start.
Then play.

Common questions readers ask
Is this strategy actually profitable? No crash strategy beats the locked house edge. The 3% edge on most aviation crash and the 1% on Cash or Crash Live applies regardless of cashout target. What strategies do is shape variance - whether you experience steady drains or occasional big wins on the way to the same expected outcome.
Should you trust the math? If the game is provably fair, yes. You can verify any round yourself with the seeds the operator reveals. We cover the verification process in our verification guide. If the game uses certified RNG instead (live formats), you trust GLI or iTech Labs auditing instead of self-verification.
How do you know whether the operator is honest? Check the license. UKGC, MGA, and NJDGE-licensed operators have regulatory consequences for cheating. Curacao-only operators have weaker enforcement but published audit reports if reputable. We always recommend verifying license status in the public registers before funding any operator account.
What is the difference between RTP and house edge? They are two sides of one coin. Subtract RTP from 100% to get house edge. 97% RTP means 3% house edge. Lower house edge is better for the player over long sessions.
Does volatility matter? Yes for variance shape, no for expected value. High volatility means rare big wins between many small losses. Low volatility means frequent small wins. Same RTP either way; different psychological feel.
Is bigger bet size better? No. Bigger bets just amplify variance. Pick stake size at 1-2% of session bankroll to survive realistic losing streaks. We cover this in our bankroll management guide.
Worked example to ground the theory
Take a typical session: $200 bankroll, 2x cashout target, $2 per round (1% of bankroll), 100 rounds.
Expected wins: 49 rounds at $4 each = $196 collected
Expected losses: 51 rounds at $2 each = $102 lost
Net expected: $196 - $200 staked = -$4. That is the 2% house edge over 100 rounds at this configuration.
Real session variance: most sessions finish between -$30 and +$30 around the -$4 expected. Some sessions you finish way up; some way down. The -2% only emerges as a long-run average over many sessions aggregated.
The takeaway: short-term variance is much louder than long-run expected value. Discipline lets you stay in the game long enough for the math to converge.
How this connects to broader crash strategy
This article is one piece of a larger picture. The full strategy framework involves:
1. Picking a cashout target you can defend mathematically. We cover this in our 2026 strategy guide.
2. Sizing stakes against expected streak depth. The math is in our bankroll guide.
3. Picking games with the highest RTP available to you. The ranking is in our RTP rankings.
4. Verifying provably fair on every round you care about. The process is in our verification guide.
Each piece supports the others. None of them individually beats the house edge - what they do collectively is help you survive the math long enough to enjoy playing.
Crash rules fit in 4 phases: pre-bet, bet close, multiplier rise, round end. Learning them takes 5 minutes; executing them with discipline takes 100 rounds. The rules are simple; the discipline is hard.

Open the Aviator playbookFrequently asked questions
What are the 4 phases of a crash game round?
Phase 1 pre-bet: bet input is open, players set stake amount and optionally auto-cashout target (~5-10 seconds). Phase 2 bet close: casino publishes the SHA-256 or SHA-512 hash of the server seed, committing cryptographically to the eventual crash point. Phase 3 multiplier rise: the active phase, multiplier climbs from 1.00x upward and players decide cashout timing (12-25 seconds typical).
Phase 4 round end: the multiplier reaches the cryptographically-determined crash point; round resolves to win (if cashed out before crash) or loss (full stake forfeited if not). Casino then reveals the server seed for verification. Total round length is 12-30 seconds depending on the eventual crash multiplier.
Can I cash out a crash bet right at the crash moment?
Mechanically possible if your click registers before the multiplier reaches the crash point; functionally rare due to human reaction lag. Average human reaction time to a visual cue is 200-300 milliseconds; the multiplier rises faster than reaction time at high values.
Setting auto-cashout at your target removes the reaction-lag problem entirely; the engine fires the cashout deterministically when the multiplier hits the target value. Manual cashouts at low targets (1.4x) typically execute 0.05-0.15x late on average due to reaction lag; at high targets (5x+) the timing precision is even worse. Auto-cashout is the recommended approach for any serious play.
What happens if I do not cash out before the crash?
Full stake is lost. The bet settles at zero; no partial credit, no refund, no recovery mechanism.
The round is binary at the cashout decision: cashed out before crash equals win (winnings = stake × cashout multiplier), did not cash out equals loss (full stake forfeited). Marketing claims that suggest otherwise ("you can recover any loss") are misleading. The rules do not include refund mechanisms for missed cashouts; the defence is auto-cashout (removes reaction lag) plus disciplined target choice (do not set targets your bankroll cannot survive missing).
How do I configure auto-cashout on Aviator?
Open the Aviator bet panel during pre-bet phase. Find the auto-cashout field above the bet button (labelled "Auto Cash Out" or similar depending on operator). Type a target multiplier value (e.g., 1.8 for the standard beginner default). Toggle the auto switch on; the icon changes to indicate auto mode active.
Click bet. The engine will execute cashout automatically at exactly the target multiplier when reached during the round, regardless of your reaction time or attention. The auto setting persists across rounds until you change it. For the deeper auto-cashout strategy with 4 documented setups, our auto-cashout strategy piece walks through configuration choices.
Are there patterns in crash games I can detect?
No. Each crash round's multiplier is determined by SHA-256 or SHA-512 hashing of fresh inputs (server seed + client seed(s) + nonce) per round; round N's outputs reveal nothing about round N+1's inputs. Pattern-detection across rounds ("after 5 low rounds, a high one is coming") is the classic gambler's fallacy.
Each round is mathematically independent of all others. The seeds for each round are committed cryptographically pre-round and are not influenced by previous round outcomes. Pattern-based prediction does not work because no pattern exists; the underlying math is independent per round.
How does Dual Bet on Aviator differ from running two regular bets?
Dual Bet runs two bets within the same round with shared multiplier curve but independent auto-cashout targets. Both legs see the same crash point; each leg cashes out independently per its own settings. Two regular bets across two consecutive rounds use two different multiplier curves with two different crash points.
The shared-curve aspect of Dual Bet is what enables the asymmetric structure (70% at 1.4x grind plus 30% at 5x lottery) where the grind covers the lottery cost most rounds because both legs see the same multiplier. Running the same configuration as two separate consecutive bets would not produce the same variance smoothing because the rounds would be independent. Dual Bet is structurally specific to Aviator (and a few clones); it is not equivalent to running two regular bets.
