How Crash Works
Crash is one of the most transparent games in online gambling — the outcome of every round is mathematically verifiable by any player. This guide explains exactly how the game works, how the multiplier is generated, what "provably fair" actually means, and what the house edge looks like in practice.
How to Play
Each round follows the same sequence:
- Betting window (5 seconds): Place your bet before the round starts
- Takeoff: The multiplier starts at 1.00× and climbs continuously
- Cash out: Click cash out at any moment to lock in the current multiplier × your bet
- Crash: The multiplier stops at a predetermined point. Anyone who hasn't cashed out loses their bet
The crash point is fixed before the round starts. The server commits to it by publishing a hash before betting opens. The actual seed is only revealed after the crash — so neither players nor the casino can change the outcome mid-round.
The Multiplier Distribution
The crash point is not random in an arbitrary sense — it follows a specific mathematical distribution. Low multipliers are more common; high multipliers are rarer. Here are the approximate probabilities:
| Crash Point | Probability of Reaching It |
|---|---|
| 1.00× (instant bust) | 2.0% |
| 1.50× or higher | ~65% |
| 2.00× or higher | ~49% |
| 3.00× or higher | ~33% |
| 5.00× or higher | ~20% |
| 10.00× or higher | ~10% |
| 100.00× or higher | ~1% |
There is no maximum multiplier — theoretically a round could reach 1000× or beyond, though the probability decreases accordingly.
The House Edge
The house edge is 2.0%, built into the algorithm in a transparent way: exactly 1 in every 50 seeds produces an instant bust at 1.00×. The other 49 out of 50 seeds produce a multiplier from the distribution above.
This means if you always cashed out at exactly 2.00×, you would win ~49% of the time at 2× and lose ~51% of the time. The long-run expected return is 98 cents per dollar wagered — a 2% house edge.
Provably Fair — How It Works
Provably fair is a system that lets you independently verify any round was not manipulated. Here's the full process:
1. Commitment (before the round)
Before betting opens, the server generates a random seed and calculates its SHA-256 hash. The hash is broadcast to all players. At this point, the outcome is mathematically locked — changing the seed would produce a different hash.
2. The Algorithm
3. Reveal (after the crash)
Once the round ends, the seed is published. Any player can run the algorithm above, plug in the revealed seed and the public salt agenagaming.com-v1, and confirm the crash point matches what the game displayed. If it matches, the round was fair.
Why this works: HMAC-SHA256 is a one-way function — you cannot reverse-engineer a seed from its hash. Publishing the hash first proves the outcome was set before the round. Publishing the seed after proves what the outcome actually was. The salt (agenagaming.com-v1) is published on the site, so any player can verify without trusting Agena Gaming at all.
Cash-Out Strategy
The house edge is 2.0% regardless of your target multiplier. Cashing out at 1.5× produces frequent small wins; waiting for 10× produces rare large wins. The expected return per dollar is the same either way.
What does change is variance. A low target (1.5×) means smoother results — less likely to bust your session bankroll in a few bad rounds. A high target (10×+) means wild swings — many losing rounds punctuated by occasional large wins.
Neither approach is "better" from an EV standpoint. The right choice depends on your risk tolerance and how long you want to play.
