Aviator by Spribe: how the crash game works
One round, one decision
Aviator is not a slot in the usual sense. Spribe released it in 2019 as a crash game: each round a small red plane takes off and a multiplier climbs from 1.00x, and at a random moment the plane flies off the screen. A bet pays the multiplier showing at the instant you press cash out; wait too long and the round ends with nothing. There are no reels, paylines or symbols, which is why the game is filed under a broad category rather than by mechanic.
Two bet panels sit under the plane, so a round can carry two stakes with different exits, such as an early cash-out on one and a longer run on the other. Auto bet repeats a stake each round, and auto cash-out closes a bet at a multiplier set in advance, which is how most regular players manage the pace.
Provably fair and shared in real time
The result of every round is generated from a server seed combined with seeds from the first three players to bet, and the hashes are published so any round can be checked afterwards. Spribe publishes a theoretical return of 97%; the figure shown on this page is the one reported by the casinos in the catalogue, and some configure the game to return less than the studio default. A live bets panel and an in-game chat show other players' stakes and cash-outs as they happen, part of what made the format popular.
High volatility is built in: most rounds end below 2x, and the rare long flights are what produce large multipliers. Other games in the catalogue with a stated RTP and volatility are listed alongside it.
