Quick version: A crash game is a provably-fair multiplier game where a rocket (or line) ascends with an exponential payout curve. You choose when to “cash out” before it crashes. The earlier you cash, the lower your multiplier; if you wait too long, you lose your bet. The math is transparent; the house edge is 1–2% depending on the casino.
Every round:
bet × multiplier (e.g., $10 × 2.5x = $25 total return, which is $15 profit after your $10 stake).The crash point is generated server-side before the round starts, using the current block hash (or equivalent source of randomness). This is why crash is “provably fair” — you can verify the crash point after the round ends using the game’s seed hash.
House edge in crash is purely mathematical: there is no RNG trickery.
Expected return = (Probability of reaching X) × (Multiplier X) + (1 - P) × (-1)
For a 2.0x multiplier with a casino-set 49% bust rate:
EV = (0.51 × 1.98) + (0.49 × -1) = 1.0098 - 0.49 = -0.01
That is, a slightly negative expected value — exactly as designed. The casino's 1-2% house edge comes from carefully tuning the multiplier odds.
Typical house edge: 1–2%, depending on the casino. This is better than slots (3–5%) and live dealer (2–4%) on a per-spin basis, but crash is much faster. You play 100+ rounds per hour vs. 10–15 spins/hour on slots.
Variance: Crash is extremely high-variance. You can hit 20x in a single round (rare, ~5% chance) and lose the next ten rounds in a row (also happens). This is why session limits and bankroll discipline are critical.
Every crash round can be verified. After a round ends, the casino reveals:
You then hash: SHA-256(hash + nonce) → crash point. If the result matches, the game is fair and not rigged.
In practice, you never do this yourself. Stake, Hit.com, and other casinos let you download batch history and spot-check. Some even auto-verify in the UI.
Don’t wing it. Decide in advance: “I cash out at 1.5x.” Auto-cash features exist for this reason. A 1.5x has ~67% hit rate; 2.0x has ~51%; 5.0x has ~20%.
Higher targets feel exciting but destroy bankroll velocity. A 1.3x hit rate of 77% let you build small, consistent gains. A 10x hit rate of 10% will bankrupt you in 10 swings.
The oldest gamble trap: “I lost $10, so I’ll bet $20 next to make it back.” Doesn’t work. High variance means a 5-loss streak is statistical and totally normal. Martingaling turns a $10 loss into a $310 loss (five bets: $10 + $20 + $40 + $80 + $160).
Flat-bet instead: bet the same % of your bankroll every hand. If your bankroll is $100, bet $2. If you lose, your next bet is still $2 (not $4).
