Aviator and crash games: how they work and what they cost

Aviator is a crash game from the developer Spribe, available since 2019. At the start of a round a multiplier begins to grow from 1x, and it keeps growing until the plane flies away. Cash out before that and you win your stake times the multiplier at the moment you cashed out; miss it and the stake is lost. Spribe states that Aviator's RTP is 97%. That means that in the long run 97 euros of every 100 euros staked come back on average, and this cost does not depend on when you cash out. What RTP is, in more detail, is explained in our article on RTP and volatility.

How an Aviator round works

The moment the plane flies away is set before the round starts, and what you see on screen only reveals that result.

Spribe's game rules describe a round like this:

• The multiplier starts at 1x and grows as the plane takes off.
• Winnings are your stake times the multiplier at the moment you cash out.
• Before each round, a random number generator sets the multiplier at which the plane will fly away.
• If you do not cash out before the plane flies away, the bet is lost.
• If your auto cash-out multiplier equals the one at which the plane flies away, the round counts as lost. For example, an auto cash-out at 1.5x loses if the plane leaves at exactly 1.5x.

You can place two bets in the same round. There is auto bet, auto cash-out at a chosen multiplier and auto play with stop conditions. The casino sets the minimum and maximum bet, the maximum win and the maximum multiplier, and if a win reaches the maximum allowed amount the game cashes it out automatically.

Rounds are short. According to the formula in Spribe's game client, the multiplier reaches 2x in about 8.4 seconds, 10x in about 28 seconds and 100x in about 55 seconds.

What an RTP of 97% means

At an RTP of 97%, every cash-out strategy costs 3 euros per 100 euros staked on average, because a target that is reached less often pays out proportionally more.

Spribe's Aviator page states an RTP of 97%, but the game rules fill in the RTP from the casino's settings. You see the exact figure at a given casino in the game rules once you open the game.

Spribe does not publish how often the plane reaches a given multiplier. Games like this are usually described with a model in which the chance of reaching a multiplier x is 0.97 divided by x. The same formula is used in Wizard of Odds' crash game calculations, and it is the only one under which a single RTP figure fits every cash-out target. Under this model:

• 1.5x is reached in 64.67% of rounds;
• 2x in 48.50% of rounds;
• 5x in 19.40% of rounds;
• 10x in 9.70% of rounds;
• 100x in 0.97% of rounds, about once in 103.

The expected return is the same for every target: 2x, for example, is reached 48.5% of the time, and 48.5% times 2 is 97%. So the loss is 3 euros per 100 euros staked wherever you cash out.

A low target feels safe but is no cheaper. At 1.01x a bet wins in 96 rounds out of 100 on average, yet each loss takes the whole stake, and the cost stays the same, 3 euros per 100 euros. The target only changes the swings: bet 1 euro on 100 rounds at a 2x target and the expected loss is 3 euros, but the typical deviation is about 10 euros either way. Five losses in a row at a 2x target can be expected about once in 28 runs of five rounds.

Two bets and doubling up

Neither two bets at once nor doubling after a loss changes the cost: the loss is always about 3% of the total amount staked.

If you cash one bet out early and the other late, each bet carries the same 3% cost, so the total loss is 3% of the two stakes combined. A split like that only changes how unevenly the results arrive.

The same applies to the Martingale system. In our calculation, with a 2x target, a 1-euro starting bet and doubling after every loss up to eight losses in a row, a run ends with a 1-euro profit in 99.51% of cases and a 255-euro loss in 0.49%. The average result is minus 3% of everything staked. Why betting systems do not beat the house edge is shown with numbers in our article on roulette strategies.

What "provably fair" proves

"Provably fair" lets you check that a round's result was not changed after bets were placed, but it does not prove that the RTP is 97%.

Spribe's explanation says the operator generates a server seed before the round and publishes its hash. At the start of the round it is combined with the seeds of the first three players, and the round result is calculated from the combined value. After the round anyone can check it in the game history.

That proves the result was fixed in advance and not changed. Spribe does not publish the formula that turns this value into a multiplier, so the 97% RTP rests on Spribe's statement and the game's certificates, not on the "provably fair" check. Spribe's list of certificates includes a random number generator and game certificate issued in Latvia.

Aviator predictors are a scam

No app can predict an Aviator round, because the result only comes into being at the start of the round, from the seeds of several participants.

Before the round starts, not all the data the result is calculated from exists yet; once it starts, the result is fixed and the same for everyone. The history of previous rounds tells you nothing about the next one, because every round is independent. This follows from Spribe's rules.

"Predictors" can also be dangerous. In June 2026 Check Point Research described fake tools, among them an "Aviator Predictor", that install malware and swap a copied cryptocurrency wallet address for the criminals' address. The investigative outlet Decode uncovered Telegram groups that sold "signals" for money and claimed the game had been hacked. If someone offers you Aviator predictions, it is a scam.

Other crash games

Crash games look alike, but their cost differs: RTP ranges from 88% to 97%.

The RTP stated by the makers of the more common crash games:

• High Flyer (Pragmatic Play) - 97.00%, also with a plane and two bets (Pragmatic Play).
• Big Bass Crash (Pragmatic Play) - 95.50%.
• Spaceman (Pragmatic Play) - 95%.
• Crash X (Turbo Games) - 96%.
• Speed Crash and Limbo (Hacksaw Gaming) - 88% to 98%; which version runs at a given casino is shown in the game rules. That means a loss of 2 to 12 euros per 100 euros. In these games you set the target before the round, and there is no cash-out button.
• JetX (SmartSoft Gaming) - the maker does not state an RTP on its page.

Before you play, open the game rules and check the RTP: two similar games can cost several times as much for the same total stake.

Where to play Aviator in Latvia

In Latvia you may play crash games only at casinos licensed by the State Revenue Service.

The Gambling and Lotteries Law does not name crash games. In the game rules published by Latvian operators they are classified as a "gaming machine game", and for gaming machines the law (Article 41(1), point 7) says winnings may not total less than 80% of stakes. Every crash game RTP we found is above that threshold.

Aviator is at all six Latvian-licensed casinos on our list. For example, Klondaika offers it in its "Crash Games" section and Betsafe in its "Crash" section, where Aviator cannot be tried for free. We list all casinos licensed in Latvia under all casinos.

Play within your means

An Aviator round lasts a few seconds, so you can play hundreds of rounds an hour, and a 3% cost adds up fast. Set a budget before you start, and if you use auto play, set stop conditions. Our responsible gambling page and our article on responsible gambling tools gather the tools that help, including the State Revenue Service's self-exclusion register. The addiction support line of the Centre for Disease Prevention and Control, 67037333, is anonymous (in Latvian). Gambling is for people aged 18 and over only.
