Crash Games Explained: Mechanics, Multipliers and House Edge
A crash game is a game of chance in which a multiplier climbs from 1.00x and stops at a random point, and you must cash out before it stops to be paid. Cash out earlier and you win more often for less. Cash out later and you win less often for more. On a game with a fixed RTP, moving your cash-out point changes the risk and leaves the house edge where it was.
How does a crash game work?
A crash game works in repeating rounds, and each round has one multiplier that rises until it crashes at a point set by the game's random system. Providers describe the format in much the same way: a curve or vehicle climbs, the multiplier scale grows, and the player must cash out before it ends.
- A betting window opens, and you choose a stake for the round.
- The round starts and the multiplier rises from 1.00x.
- You cash out manually, or at a target set in advance if the game offers an automatic option.
- If you cashed out before the crash, you receive your stake multiplied by the figure at that moment.
- If the crash arrives first, the stake is lost.
Rounds are short and the next begins almost at once. That pace can push a lot of money through the game in a short time, which is the main practical risk with the format.
What does the multiplier mean in a crash game?
The multiplier is what your stake would be worth if you cashed out at that instant. A $5 stake cashed out at 2.00x returns $10, which is $5 of profit. A return of 1.00x simply gives back the stake. Some games can end a round at or very close to the bottom of the scale, which loses every open bet. The rules screen of each game explains how it handles that case.
How are crash game odds calculated?
On a game with a constant RTP at every cash-out point, the chance of reaching a multiplier equals the RTP divided by that multiplier. That follows from the definition of RTP: the payout times the chance of receiving it has to equal the expected return. The table uses an illustrative RTP of 97%. It is a model and not the published maths of any particular game, so always read the game's own rules.
| Cash-out target (x) | Chance of reaching it (%) | Return if reached, per $1 ($) | Expected return, per $1 ($) |
|---|---|---|---|
| 1.50x | 64.7% | $1.50 | $0.97 |
| 2.00x | 48.5% | $2.00 | $0.97 |
| 5.00x | 19.4% | $5.00 | $0.97 |
| 10.00x | 9.7% | $10.00 | $0.97 |
| 100.00x | 0.97% | $100.00 | $0.97 |
The last column doesn't move. A low target wins often and pays little. A high target wins rarely and pays a lot. Over a large number of rounds, both are expected to return 97 cents per dollar staked under this model.
What is the house edge on a crash game?
The house edge on a crash game is 100% minus its RTP, so it would be 3% on a 97% game. Published RTP figures vary between games, and we have not quoted any here because a figure on a third-party page is not proof of what a given game is running. Take the number from the game's own rules or from the provider's official page, and treat it as a long-run average. Our guide to RTP and volatility explains why one session can sit far from it.
What does expected loss look like at crash game speed?
Expected loss is total stakes multiplied by the house edge, and fast rounds raise total stakes quickly. With a $2 stake, 30-second rounds and a 3% edge, one hour is 120 rounds, $240 of turnover and an expected loss of $7.20. Doubling the stake doubles that figure. A run of wins early on doesn't change the rate.
Can you predict when a crash game will crash?
No, you can't predict the crash point of a round from earlier rounds. Round histories are displayed prominently, which invites pattern-spotting, yet a run of low crashes doesn't make a high one due. Tools or channels that claim to forecast rounds should be treated with deep suspicion. Staking systems that double after a loss don't help either: they raise the amount at risk and can reach your limit within a handful of rounds, without changing the edge on any of them.
What does provably fair mean in a crash game?
Provably fair means the game publishes cryptographic data that lets a player check a round's result was not altered after the bet was placed. That is a real feature with a narrow scope. It can show that a single outcome matches its published inputs. It doesn't reduce the house edge, it doesn't establish that a site will pay a withdrawal, and it doesn't give an operator any standing under Australian law.
Are real-money crash games legal in Australia?
Real-money crash games sit within the online casino-style category that may not be offered to people in Australia, on our reading of the Interactive Gambling Act 2001. The Act's definition of a gambling service includes a game of chance, including an electronic game, that is played for money or anything else of value where the customer pays to play. Crash games aren't named in the official material we reviewed, but we are not aware of any exemption that would cover them. The NSW government says more generally that offshore operators provide no consumer protection in Australia.
