Provably Fair Gaming at Crash Arcade

The system in one paragraph

Crash Arcade game outcomes are generated on the server using a provably fair random system. The system uses a server seed, a client seed, a nonce and HMAC-SHA256. Those four inputs produce a deterministic random stream: the same inputs always yield the same output, and changing any one of them changes the result completely.

Why it matters

Your bet is connected to the relevant random sequence before the game result is calculated. This approach is designed so that a completed bet result cannot simply be altered afterward. The outcome is not being invented while you watch it; it is being revealed.

That ordering is the whole point of a provably fair design. In a system where the result is generated after the bet is known, the platform could in principle react to your stake. In a system where the random stream is fixed first and the bet is bound to it, that reaction is not available.

What each input does

Server-side results

Game outcomes are determined by the server rather than by animations shown on your device. The animation represents the result. It does not independently decide the result.

This is the single most misunderstood part of crash games. The plane in Aviator is not deciding when to end the flight while it climbs. The end point was already in the random stream before the animation started. Nothing you do to your screen — tapping faster, closing the app, losing connection — changes a result that already exists on the server.

The same system across all seven games

The random stream drives every game on the platform, in whatever shape that game needs it:

• Aviator and JetX — the point at which the round ends
• Chicken Road — the outcome of each lane attempt
• Mines — the positions of the mines on the 5x5 grid, fixed before your first click
• Dice — the number between 0.00 and 99.99
• Andar Bahar and Dragon Tiger — the cards dealt

Errors and server records

Where a clear technical or settlement error occurs, Crash Arcade may investigate the relevant round or transaction using server records. Because outcomes and bets are recorded server-side, a disputed round can be examined rather than argued about. See the terms and conditions.

Questions provably fair does not answer

• It does not tell you what the next result will be — nothing does
• It does not make a losing streak evidence of a problem
• It does not mean a high multiplier is "due" after low ones
• It does not remove the house edge from any game

If you are looking for a system, a pattern or a prediction tool, none exist. Each round draws independently from the same distribution. Play within limits you set in advance.
