Crash Games Explained: How They Work and Why They Are Risky

Updated: 3 November 2026

Crash games are among the fastest games in any online casino. A multiplier climbs from 1.00x, and at a random moment it stops: the game “crashes”. If you cash out before the crash, your stake is multiplied. If you do not, you lose it. The best-known example is Aviator by Spribe, where a small plane takes off and flies away. Many other crash games follow the same idea with rockets, cars or other pictures. This page explains how crash games work in general, why no pattern or “system” can beat them, and how to keep a session under control.

How a crash game works

Almost every crash game follows the same four steps:

1. You place a stake before the round starts, during a short countdown.
2. The multiplier starts climbing from 1.00x: 1.10x, 1.50x, 2.00x and higher. On the screen, something rises or flies.
3. You cash out whenever you choose. You get your stake multiplied by the multiplier at that moment. For example, KSh 200 cashed out at 2.50x returns KSh 500.
4. The crash comes. At a random point the round ends. Any stake that has not been cashed out is lost.

The crash can come almost at once, close to 1.00x, or after a very high multiplier. Nobody knows in advance. The amounts above leave out tax: deposits carry a 5% excise duty and tax may be withheld from payouts (see betting law and tax in Kenya).

Multipliers: the trade-off

The idea of a crash game is a simple trade-off:

• A low cash-out point (for example 1.20x) is reached in many rounds, but pays little each time.
• A high cash-out point (for example 10x) pays much more, but is reached in far fewer rounds.

The game’s maths balances these so that, whatever point you choose, the house keeps its edge over time. No cash-out point is “safe”, and none is “best”. Changing the point only changes how often you win and how much, not who has the edge.

RTP and the house edge

Every crash game has an RTP (return to player): the share of all money staked that is paid back to players over a very long time. Spribe states an RTP of 97% for Aviator. That means about KSh 97 of every KSh 100 staked by all players over a very long time goes back as payouts, and about KSh 3 stays with the house.

Other crash games have their own RTP, which you should be able to find in the game’s info or help screen. RTP is a long-run average: in a short session you can be far above or far below it. Read more in RTP explained.

Provably fair

Many crash games, including Aviator, use a provably fair system. In Aviator, each round’s result is set from secret values, called seeds, that come from the game’s server and from players. After the round, the seeds are revealed so that anyone can check the result was not changed.

Provably fair shows fairness after the round. It does not reveal the result before the round, so it cannot be used to predict anything. Other crash games may describe their own system in the rules screen; read it there.

Auto cash out and auto bet

Most crash games have two automatic options.

Auto cash out

You set a multiplier in advance, for example 1.50x. If the round reaches it, the game cashes out for you. If the crash comes earlier, you lose the stake. Auto cash out helps you stick to a plan, and it removes the temptation to “wait a bit longer”. It does not change the house edge.

Auto bet

The game places the same stake for you, round after round, without you tapping anything. Because crash rounds last only seconds, auto bet can place a very large number of bets in a short time. That is why auto bet is the fastest way to use up a budget.

If you use auto bet at all, set a limit on the number of rounds and a loss limit where the game offers one.

Two bets at once

Some crash games, including Aviator, let you place two stakes in the same round and cash them out at different times. This splits your money into two bets. It does not reduce the house edge.

Why patterns do not exist

Crash games show a history of recent multipliers. It is natural to look at that list and see patterns: “three low rounds, so a high one is coming”, or “it always crashes early after a big round”. These patterns are not real.

• Each round is independent. The result of one round has no link with the next.
• Low rounds do not build up to a high one. A high multiplier is never “due”.
• Streaks happen by chance. In random results, runs of low or high rounds appear naturally. They do not predict what comes next.
• Doubling your stake after a loss (often called martingale) does not fix this. A short run of losses can take your whole budget, and stake limits stop the system from working.

Apps, websites and Telegram groups that sell “predictions” or “signals” for crash games cannot work, and some of them are used to steal money or M-Pesa details. Read why an Aviator predictor cannot work.

Session limits: the most important tool

Crash games are fast, simple and exciting, and that mix makes it very easy to play longer and stake more than you planned. A clear set of limits matters more in crash games than in almost any other game.

Before you start a session, decide:

• A money limit: the amount you are ready to lose as the cost of entertainment. When it is gone, stop.
• A time limit: for example 20 or 30 minutes. Set an alarm on your phone.
• A stake size: one fixed stake per round, not raised after losses.
• A stop rule for wins too: if you are ahead, decide in advance when you will stop.

Then use the tools in your casino account: deposit limits, time-outs and self-exclusion. Through the GRA you can also ask operators to bar you for a set period.

Watch for these warning signs:

• You top up your account during a session.
• You raise your stake to win back losses.
• You play with money meant for rent, school fees, food or debts.
• You feel restless or upset when you are not playing.

If any of these sound familiar, take a break and read our responsible gambling guide.

Before you play any crash game

• Check that the operator is licensed: read licensed casinos in Kenya: how to check.
• Open the rules screen and read the minimum and maximum stakes, any maximum payout and the RTP.
• Pay only through the paybill or till number shown in the operator’s official app or website. See casino and M-Pesa.
• For Aviator in detail, read how Aviator works. For other game types, see casino games in Kenya.

Frequently asked questions

What is a crash game? A casino game where a multiplier climbs until a random crash. You must cash out before the crash to get your stake multiplied.

Which crash game gives the best chance to win? None gives you an edge. Each has its own RTP, shown in the rules screen, and each keeps a house edge over time.

Can I see when the next crash will come? No. Each round is random and independent, and provably fair seeds are only revealed after the round.

Is auto cash out a strategy? It is a tool to stick to a plan, not a way to win. It does not change the house edge.
