What Aviator is
Aviator is a crash game from Spribe, one of the studios that brought the format from crypto sites into regular online casino lobbies. According to Spribe, the game first went live in February 2019, and a rebuilt Aviator 2.0 later arrived with faster loading and a lighter client for budget phones and slow connections.
There are no symbols, paylines or bonus rounds. Each round is a single curve: a small plane takes off, a multiplier starts at 1.00x and climbs, and at a random point the plane flies away. If you pressed Cash Out before that moment, your stake is multiplied by the value on screen. If you did not, the stake is gone.
Spribe lists the game's return to player at 97%, and the round results come from a provably fair process rather than a hidden server roll, which we explain in detail below. If you are new to the idea of RTP, our RTP guide covers how a percentage like this is calculated and why it only describes the long run.
How a round works, step by step
- Betting window. Between rounds you set a stake in one or both bet panels. You can type an amount, use the preset buttons or step it with plus and minus. A bet can be cancelled until the round starts.
- Seeds lock in. The operator's server seed for the round is already fixed, and its SHA256 hash was visible in advance. The client seeds of the first three players to bet are added to it.
- Take-off. The multiplier starts at 1.00x and rises. The in-game rules give the growth curve as multiplier = floor(100 x e^(0.000083 x ms)) / 100, where ms is the time since take-off.
- Cash out. Press Cash Out on either panel at any moment, or let Auto Cash Out do it at your chosen value. Your win is your stake times the multiplier at that instant.
- Fly away. At the pre-generated crash point the plane leaves. Any bet still active is lost, and the result is added to the strip of recent multipliers at the top.
The growth formula tells you something practical about pace. Working it through, the multiplier reaches 1.50x after roughly 4.9 seconds, 2.00x after about 8.4 seconds, 10x after about 27.7 seconds and 100x after about 55 seconds. Low targets therefore resolve quickly, while high targets mean watching the plane for close to a minute.
Worked cash-out examples
| Stake | Cash-out point | Returned | Profit |
|---|---|---|---|
| 2.00 | 1.85x | 3.70 | 1.70 |
| 1.00 | 1.20x | 1.20 | 0.20 |
| 5.00 | 3.00x | 15.00 | 10.00 |
| 0.50 | 25.00x | 12.50 | 12.00 |
The first row is the typical low-target play: a 2.00 stake cashed at 1.85x returns 3.70, a profit of 1.70. Note the edge cases the rules spell out. If the plane flies away at 1.25x, the last value it actually reached was 1.24x, and an Auto Cash Out set at exactly 1.25x loses. The same applies at any value: a target equal to the crash point counts as a loss, so the multiplier has to pass your number, not just touch it.
Two bets at once
Aviator's signature feature is the second bet panel, added with the plus icon in the corner of the first. The two bets are fully independent: separate stakes, separate Cash Out buttons and separate auto settings. A common setup pairs a safe target with a speculative one.
Say you place 1.00 on each panel, with Auto Cash Out at 1.50x on the first and a manual target of 3.00x on the second. If the round runs to 4.20x and you cash the second at 3.00x, you get 1.50 plus 3.00, so 4.50 back on 2.00 staked. If the plane leaves at 2.40x before you press the second button, you get 1.50 back on 2.00, a net loss of 0.50. If it leaves at 1.10x, both bets lose. Two panels spread your outcomes; they do not change the expected return of either bet.
Auto Play and Auto Cash Out
Both automation tools live on the Auto tab of each bet panel. Auto Cash Out closes the bet as soon as the multiplier passes your entered value, which removes reaction time from the equation. Auto Play places the same bet each round for a number of rounds you choose, and you must add at least one stop condition:
- Stop if cash decreases by a set amount, a built-in loss limit.
- Stop if cash increases by a set amount, a profit lock.
- Stop if single win exceeds a set amount.
With Auto Bet on but Auto Cash Out off, bets are placed for you but you still have to press Cash Out every round. For hands-off play you need both switched on. If your connection drops while a bet is active, the rules say the game cashes you out at the current multiplier and credits the win.
Provably fair: how the crash point is generated
Spribe's rules state that the crash multiplier for each round is generated before the round starts, from four participants rather than by the server alone. The operator creates a server seed of 16 random characters and publishes its SHA256 hash ahead of time, so it cannot be swapped later. Each player has a client seed, which you can change in the Provably Fair settings. When the round starts, the server seed is merged with the client seeds of the first three bettors, the combined string is hashed with SHA512, and the round result is derived from that hash.
To check a round, open My Bets or the Top tab and press the fairness icon next to it. You will see the server seed, the three player seeds, the combined hash and the result. If you want your own seed to take part, you need to be among the first three players to bet in that round. Aviator also offers multiple rooms, and each room generates its results independently with its own seeds.
How RTP works in a crash game
In a slot, RTP comes from a paytable and reel strips. In Aviator it comes from the distribution of crash points. The rules put it plainly: with an overall theoretical return of 97%, on average 3 rounds in every 100 end with the plane flying away at the very beginning. That built-in instant loss is where the house edge sits.
What matters for you is that the 97% figure describes every cash-out target, not a specific one. Cashing out early at 1.20x wins often but pays little; waiting for 10x wins rarely but pays a lot. Over a large number of rounds, each approach returns about 97 units for every 100 wagered. You are choosing volatility, meaning how bumpy the ride is, not a better return. A 1.20x target gives small, frequent results; a 20x target gives long losing runs broken by occasional big hits.
Why martingale does not beat Aviator
Progressions look tempting in a crash game because low targets hit so often. Here is the problem with the classic doubling plan at a 2.00x target. Start at 1.00; after a loss bet 2.00, then 4.00, 8.00 and 16.00. Five losses in a row cost 31.00, and the sixth bet needs 32.00 just to finish 1.00 ahead. Streaks like that are rare but certain to occur over enough rounds, and bet limits or your balance stop the chain long before it can recover.
The deeper issue is arithmetic. Every bet in the sequence carries the same 3% edge, so the expected loss is 3% of everything you wager. A progression increases the total wagered, which increases the expected loss. It trades many small wins for a rare, large drawdown, and the average stays the same.
A sounder plan is flat staking with a fixed session budget. Decide the total you are willing to lose, keep each stake to a small slice of it, and set the Auto Play loss limit to match. If you want the thrill of high targets, cut the stake instead of raising it.
Social features and the in-game panels
Aviator is built as a shared room. The Live Bets panel on the left shows every bet in the current round and who cashed out at what value. The Top tab ranks the biggest wins and multipliers daily, monthly and all time. The chat on the right lets players talk, and big wins are posted automatically.
The game menu also holds the Limits screen, which shows the minimum and maximum bet and the maximum win for your casino. Operators set these values, so they vary between sites. When a win reaches the maximum, the game cashes out automatically.
Trying Aviator in the free demo
The demo above runs the official Spribe build with play money, so you can test cash-out timing and the two-panel setup without risk. Our free demo guide covers what demo play can and cannot tell you. In Aviator, focus on three things: how fast the multiplier moves at your target, how Auto Cash Out behaves right at the crash point, and how a long losing run feels at your planned stake.
Before switching to real money, open the rules and the Limits screen in your casino's version and note the listed RTP, minimum bet and maximum win. If you like the format, compare it with JetX, which allows up to four bets per round, and Spaceman with its half cash-out. For something without a timer, Spribe's Mines lets you cash out at your own pace.
Where to play Aviator for real money
Frequently asked questions
What is the RTP of Aviator?
Spribe lists Aviator at 97% RTP. The in-game rules explain that, on average, 3 of every 100 rounds end with the plane flying away at the very beginning. The percentage is a long-run average across all cash-out targets, not a promise for any session.
Is Aviator provably fair?
Yes. The operator's server seed is hashed and published before the round, then combined with the client seeds of the first three bettors into a SHA512 hash that sets the crash point. You can open any round from My Bets and check the seeds and hash yourself.
Can you place two bets in Aviator?
Yes. Press the plus icon on the first bet panel to add a second one. Each panel has its own stake, Cash Out button and auto settings, so you can cash one bet early and let the other run.
How does Auto Cash Out work in Aviator?
You enter a multiplier on the Auto tab and the bet is cashed out automatically when the plane passes it. If the plane flies away exactly at your chosen value, the bet counts as lost, so the multiplier must go beyond your target.
What is the maximum win in Aviator?
The maximum win and maximum multiplier are set by each casino and shown in the game's Limits screen. When a win reaches the cap, Aviator cashes out automatically. Check the limits in your casino's version before playing.
Does a martingale strategy work in Aviator?
No. Every bet carries the same house edge, so doubling after losses only raises the total amount wagered and the expected loss with it. It swaps frequent small wins for rare, large losing streaks that bet limits make impossible to recover.
What happens if I lose connection during a round?
According to Spribe's rules, if your connection drops while a bet is active, the game cashes it out at the current multiplier and adds the win to your balance. A hardware or software malfunction voids affected bets, which are refunded.
