Aviator

Aviator is Spribe's crash game: cash out before the plane flies away. You can place two bets at once, each with its own auto cash-out, and the screen shows in-game chat, and every player's bets and wins in view. For provable fairness, the server seed is combined with players' client seeds into a SHA-512 hash. Spribe lists an RTP of 97.00%; it publishes no max win (bigwinboard gives 10,000×).
