About AviUltra
AviUltra is a crypto crash game. A plane climbs, the multiplier climbs with it, and you cash out before it flies away. Wait too long and the round is lost. That is the whole game.
What makes us different
Most crash games cap every player at the same small maximum bet, so a $10 balance and a $10,000 balance play against the same ceiling. That never made sense to us.
AviUltra ties your max bet to your balance. Win big, stake bigger on the very next round. That is the Ultra rule, and it is why the site exists.
The Ultra rule
Your maximum bet is the greater of $100 or 10% of your balance. It is recalculated on every bet, so a winning streak unlocks bigger bets immediately, and a losing streak tightens them automatically.
There is no separate high-roller table and no request-a-raise form. The rule applies to everyone.
Provably fair
Every round commits a SHA-256 hash of its server seed before betting opens, then reveals the seed the moment the plane crashes. Anyone can recompute the crash point from the revealed seed and confirm it matches what actually happened.
We built a public verifier so you can do that check yourself in the browser. Paste the seeds from any round and see the crash point derived in front of you: /provably-fair.
Crypto in, crypto out
Deposits and withdrawals are in crypto. Your wallet balance is denominated in USD so numbers stay readable while the market moves.
Withdrawals are reviewed and paid every Monday. Minimum withdrawal is $10. No hidden fees on our side; you only pay the network fee your withdrawal costs to send.
