How Crash Works
Crash is a multiplier game where you place a bet and watch the multiplier climb. Cash out before it crashes to lock in your winnings — but wait too long and you lose everything.
How to Play
- 1
Place your bet
Enter your wager amount before the round begins. You can also set an auto cash-out multiplier to automatically secure your winnings at a target value.
- 2
Watch the multiplier climb
Once the round starts, the multiplier begins at 1.00x and climbs. The longer it runs, the higher the potential payout.
- 3
Cash out in time
Click the cash-out button at any point to lock in your current multiplier. Your payout is your bet multiplied by the cash-out value.
- 4
Or crash and lose
If the game crashes before you cash out, you lose your entire bet for that round. The crash point is determined by a provably fair algorithm.
Odds & House Edge
The crash multiplier curve is mathematically designed so that the average expected return across all possible outcomes is below 100%. This creates the house edge without any visible fee.
The crash point for each round is predetermined by the provably fair system before any bets are placed. The distribution of crash points follows a curve where lower multipliers are more likely than higher ones.

Provably Fair
Every crash outcome on CaseRush.gg is determined using our provably fair system. Before each round, a server seed hash is published. After the round, the full server seed is revealed so you can independently verify the result was not manipulated.
The system uses HMAC-SHA256 with a combination of server seed, client seed, and nonce to generate verifiable random outcomes.
Frequently Asked Questions
What is the maximum multiplier?
There is no fixed maximum — the multiplier can theoretically reach very high values. However, higher multipliers are exponentially less likely to occur.
How does auto cash-out work?
Set a target multiplier before the round starts. If the game reaches your target, you are automatically cashed out at that exact multiplier. If the game crashes before reaching your target, you lose your bet.
Can the crash point be 1.00x?
Yes. The game can crash instantly at 1.00x, meaning no one wins that round. This is part of the provably fair distribution.
Are crash outcomes provably fair?
Yes. Each round's crash point is determined before bets are placed using HMAC-SHA256 with a server seed, client seed, and nonce. You can verify any round after it completes.
