A crash game is a type of casino game where a multiplier starts at 1.00x and rises rapidly. You place a bet before the round starts, then decide when to cash out. If you cash out at 3.00x, you get 3× your bet. If the game crashes before you cash out, you lose everything. That’s it — no reels, no cards, no dealer. Just a rising number and a decision.
The crash point is predetermined by the game’s algorithm before you bet. No amount of timing, gut feeling, or “pattern reading” changes what was already decided. This guide explains the core mechanics, walks you through a typical round, and points you to the deep-dive guides for the math, verification, and RTP data.

How a Round Actually Plays Out
Here’s what happens in every crash game round, step by step:
Types of Crash Games
The core mechanic is the same across all crash games, but there are a few distinct formats:
Classic crash (Aviator, JetX, BGaming Crash) — a single rising multiplier, cash out manually or with auto-cashout. Most crash games follow this format. Some allow 2–3 simultaneous bets.
Partial cashout crash (Spaceman) — same rising multiplier, but you can cash out 50% of your bet and let the other half ride. This is unique to Pragmatic Play’s Spaceman.
Live dealer crash (Cash or Crash by Evolution) — hosted by a real dealer in a studio. Slower rounds, different presentation, but the underlying probability is similar.
Themed crash (Lucky Jet, F777 Fighter, Goblin Run) — same math as classic crash, wrapped in different visuals. A rocket, a jet, a goblin — the theme changes, the house edge doesn’t.

The Algorithm: How the Crash Point Is Decided
Every crash point is calculated before the round starts using a cryptographic algorithm. The result is predetermined — it doesn’t change based on how many people bet or when you click cash out.
The core process: a random number is generated using SHA-256 hashing, then converted into a multiplier using a formula that includes the house edge as a parameter. Roughly 1–3% of rounds crash instantly at 1.00x — this is how the house edge is enforced.
Two key facts: every round is independent (the algorithm has no memory), and no one — not the casino, not the player — can predict the crash point before the round starts.

Your Odds at Every Multiplier
The probability of reaching any multiplier follows a simple formula. For a game with 97% RTP:
| Target | Probability | Win on $10 Bet |
|---|---|---|
| 1.50x | ~64.7% | $5.00 |
| 2.00x | ~48.5% | $10.00 |
| 5.00x | ~19.4% | $40.00 |
| 10.00x | ~9.7% | $90.00 |
The house edge is identical regardless of which multiplier you target — whether you cash out at 1.5x or 50x, the expected loss per bet is always 3% on a 97% RTP game. The only thing that changes is variance.

Is It Fair? How Verification Works
Many crash games use Provably Fair technology — a cryptographic system that lets you verify every round after it ends. The casino commits to the result before you bet (by publishing a hash), and you can check the math yourself after the round.
Some crash games use certified RNG instead — tested by independent labs but not individually verifiable by players. Both systems are legitimate, but Provably Fair gives you more control.

Common Mistakes That Cost Players Money
Chasing Patterns That Don’t Exist
“The game crashed below 2x five times in a row — a big one is coming.” This is the Gambler’s Fallacy. Each round uses a fresh random number. The algorithm has no memory. After ten consecutive crashes at 1.00x, the probability of the next round reaching 100x is still exactly 0.97%. The game doesn’t owe you anything.
Manual Cashout vs Auto-Cashout
Playing manually feels more exciting, but it introduces a real problem: latency. If your internet connection stutters by 200 milliseconds, your click might register after the crash. Auto-cashout sends the command to the server before the round begins, eliminating this risk entirely.
Ignoring the RTP Settings
Some casinos allow operators to configure different RTP levels for the same game. Aviator, for example, can run at 97%, 96%, or even 94% depending on the casino’s settings. A 3% difference in RTP means 3× more instant busts and significantly faster bankroll depletion. Always check the “?” or info button in the game interface.
Trusting “Predictor” Apps
No app, browser extension, or Telegram bot can predict crash game outcomes. The result is determined by cryptographic hashing — the same technology that secures Bitcoin transactions. Anyone selling a “crash predictor” is running a scam.
Frequently Asked Questions
Are crash games rigged?
Legitimate crash games using Provably Fair technology are not rigged — you can mathematically verify every round. However, the house edge (typically 1–3%) means the casino always profits long-term. This isn’t “rigging”; it’s the business model of every casino game. The risk comes from unlicensed sites that may use manipulated algorithms without independent verification.
Can I predict the crash point?
No. Crash games use Random Number Generators where each round is an independent event. Past results have zero influence on future outcomes. No software, app, or “pattern analysis” can predict what the RNG will produce. Anyone claiming otherwise is selling a scam.
What is the best multiplier to cash out at?
There is no mathematically “best” multiplier. The house edge is identical regardless of your target — 3% on a 97% RTP game whether you cash out at 1.5x or 50x. The only difference is variance: low multipliers give frequent small wins, high multipliers give rare large wins. Choose based on your bankroll management strategy and risk tolerance.
Does crash have a pattern?
No. Each round uses an independent random number — the algorithm has no memory. After ten consecutive crashes below 2x, the probability of the next round reaching 100x is still exactly 0.97% (on 97% RTP). What looks like a “pattern” in round history is a cognitive bias called the Gambler’s Fallacy.
Is it legal to play crash games in Canada?
Online gambling laws in Canada vary by province. Generally, playing on internationally licensed platforms is not prohibited for individuals. However, we recommend checking your provincial regulations. For more details, see our crash gambling Canada guide.
How long does a crash game round last?
Most rounds last between 5 seconds and 2 minutes. Instant busts (1.00x) end in under a second. High multiplier rounds (50x+) can take 30–60 seconds. The speed makes crash games one of the fastest casino game formats.
What is the maximum multiplier in crash games?
It varies by game. Aviator caps at 100x, JetX and BGaming Crash have no theoretical cap (though multipliers above 1,000x are extremely rare). Spaceman caps at 5,000x. See our complete RTP table for max multipliers by game.
Can I play crash games for free?
Some platforms offer demo mode where you play with fake money. This lets you understand the mechanics without risk. See our free crash games guide for platforms with demo mode.
What is auto-cashout and should I use it?
Auto-cashout lets you set a target multiplier before the round starts. If the game reaches your target, you cash out automatically — no need to click. We recommend it for consistency: manual cashout introduces latency risk (your click might arrive after the crash).
