How Aviator works
Aviator follows the crash game format with a distinctive visual twist. When a round begins, a small airplane takes off from the bottom of the screen and starts climbing. As the plane ascends, a multiplier increases in real-time, starting at 1.00x and climbing continuously. Your goal is to cash out your bet before the plane flies away and the round ends.
At the start of each round, you place your bet. You can place up to two simultaneous bets per round, which is a feature unique to Aviator and central to several popular strategies. Once the plane starts flying, the multiplier begins increasing. You can manually click the cash-out button at any time, or you can set an auto cash-out multiplier before the round begins.
If you cash out at 2.00x, you receive double your bet. If you cash out at 5.00x, you receive five times your bet. But if the plane flies away before you cash out, you lose your entire bet for that round. The crash point is fixed by a provably fair process that combines a Spribe server seed (committed by its hash before the round) with the client seeds of the first three players to bet, so the result cannot be changed after bets are placed.
One of Aviator's most engaging features is its social element. You can see other players' bets and cash-outs in real-time on the left side of the screen. This creates a shared experience where you watch others cash out at various multipliers, adding psychological pressure and excitement to each round. You can see when someone cashes out at 50x while you took 2x, and you can watch others lose when they get greedy.
Rounds in Aviator are fast, typically lasting between 5 and 30 seconds, though occasionally the multiplier climbs to 100x or higher, which can take longer. The speed means you can play dozens of rounds in a short session. This pace is both appealing and dangerous, as it can lead to rapid wagering if you are not disciplined about your bet sizing.
Aviator RTP & house edge
Aviator’s widely cited provider default RTP is 97%, which translates to a 3% house edge. Spribe also lets operators run lower RTP tiers such as 96%, so check the live figure in the game’s info menu at your casino. Check the maximum multiplier and bet range in the game’s info panel too, along with the live RTP.
A 3% house edge means that for every $100 you wager across all rounds, you can expect to lose approximately $3 on average over the long run. This is higher than some in-house crash games, such as Stake’s at a 1% house edge (99% RTP), though not all in-house versions are cheaper: Roobet’s works out to about 4%. Over hundreds of bets, this difference compounds substantially.
To put it in perspective: if you wager a total of 1 BTC across a session, Aviator's expected house take is 0.03 BTC, while Stake's Crash game would take approximately 0.01 BTC. That is a threefold difference in expected cost for what is essentially the same type of game.
Why is Aviator’s edge higher? Spribe is a third-party provider that licenses Aviator to casinos, and it sets the RTP tiers operators can choose from. In-house crash games are priced by the casino itself, and some (Stake’s, for example) choose a 1% edge.
Because operators can choose among Spribe’s RTP settings, the figure is not guaranteed to be identical everywhere: our BC.Game and Stake reviews treat 97% as the baseline, but always confirm the live RTP in the game’s info menu before you play.
Aviator vs Crash games
Because Aviator popularized the crash format for mainstream casino audiences, many players assume all crash games are the same. They are not. Understanding the differences can save you significant money over time.
Aviator (Spribe) vs Stake Crash
Stake’s Crash is an in-house game with a 99% RTP (see our Stake Crash page) compared to Aviator’s 97% default. It has a simpler interface without the airplane animation and does not offer Aviator’s dual-bet panels, but the 2-point RTP difference makes it the better long-run deal for players focused on value.
Aviator vs Roobet Crash
Roobet’s Crash does not have a better edge than Aviator. Roobet does not print a Crash RTP on its public pages; its own verifier busts 1 round in 25 at 1.00x and prices the rest fairly, which works out to about 96% RTP (a ~4% edge), per our Roobet Crash page. On RTP alone, Aviator at 97% is slightly better, and Stake’s 99% Crash is better than both.
When Aviator makes sense
Despite the higher house edge, Aviator has legitimate advantages. The dual bet feature allows you to run two different strategies simultaneously in a single round. The game is available at far more casinos than any in-house crash game, so if your preferred casino does not offer an in-house crash game, Aviator may be your best option. The polished UI and airplane animation also create a more engaging visual experience that many players prefer.
Ultimately, if you have access to a 99% RTP crash game and a 97% RTP Aviator on the same platform, the crash game is the better choice mathematically. If you prefer Aviator’s features and presentation, the 2-point difference is the price of that preference.
Best Aviator strategies
No strategy can overcome the 3% house edge in Aviator. However, your approach to cash-out targets, bet sizing, and the dual bet feature significantly impacts your variance and session experience.
Conservative auto cash-out (1.5x - 2.0x)
The simplest approach is an auto cash-out at a low multiplier. The probability of a round reaching multiplier M is approximately 0.97 ÷ M at the 97% default. At 1.5x, about 64.7% of rounds reach your target; at 2.0x, about 48.5%.
With a 1.5x auto cash-out, you win about 64.7% of the time with a 0.5x profit per win, and lose about 35.3% of the time with a 1.0x loss. Your expected value per round is (0.647 × 0.5) − (0.353 × 1.0) ≈ −0.03, a 3% expected loss per bet. Because the hit probability is 0.97 ÷ M, the expected return is 0.97 at every cash-out target: the target changes variance, not the edge.
The advantage of low cash-out targets is consistency. You will have more winning rounds than losing rounds, which feels psychologically rewarding and extends your session length. The disadvantage is that a single loss wipes out multiple small wins, so losing streaks can be frustrating even though they are statistically normal.
The dual bet strategy
Aviator's dual bet feature is its most strategically interesting mechanic. You place two bets simultaneously: one conservative bet with a low auto cash-out (say 1.5x), and one aggressive bet with a higher target (say 5x or 10x). The idea is that the conservative bet generates frequent small wins that offset losses on the aggressive bet, while the aggressive bet occasionally delivers a large payout.
A common configuration is to put 75% of your round budget on the conservative bet (1.5x auto cash-out) and 25% on the aggressive bet (no auto cash-out, manual cash-out when it feels right, or a high target like 8x-10x). This creates a balanced risk profile where you are not bleeding your bankroll quickly but still have exposure to big wins.
The dual bet strategy does not change the expected value. Both bets independently face the 3% house edge. What it does change is your variance profile: you experience fewer devastating losing streaks while maintaining the possibility of hitting a significant multiplier. For many players, this psychological balance makes sessions more enjoyable.
Martingale in Aviator: A warning
The Martingale system, where you double your bet after each loss, is particularly dangerous in fast games like Aviator. With a 2x auto cash-out, you lose about 51.5% of rounds. A streak of 5 consecutive losses, which is not uncommon, means your 6th bet is 32x your original. A streak of 8 losses pushes your 9th bet to 256x your original.
The Martingale does not change your expected loss, it merely concentrates your risk into rare but catastrophic losing events. Combined with Aviator's 3% house edge, the math is firmly against progressive betting. Flat betting at a consistent 1-2% of your session bankroll is far more sustainable and equally valid from an expected value perspective.
Session management
Because Aviator rounds are so fast, it is easy to play 100+ rounds in a single session without realizing how much you have wagered. If your bet is $10 per round and you play 100 rounds, you have wagered $1,000 total. At a 3% house edge, your expected loss is $30. Set a hard limit on either the number of rounds or total amount wagered before you start, and stop when you hit it.
A practical approach is to bring a fixed session bankroll, set your bet at 1-2% of that bankroll, and commit to stopping after a certain number of rounds or when you hit a profit target. For example: start with $500, bet $5-10 per round, play a maximum of 50 rounds, and cash out if your balance hits $700 or stop if it drops to $350.
Where to play Aviator
Aviator is one of the most widely distributed casino games in the world. It is available at hundreds of online casinos across both the crypto and traditional gambling markets. Here are the top platforms for playing Aviator with cryptocurrency.
BC.Game
BC.Game hosts the official Spribe Aviator game alongside its own in-house crash game, so you can compare both at the same casino. It supports 150+ cryptocurrencies. Note that BC.Game does not publish a withdrawal processing time (see our BC.Game review).
Bitstarz
Bitstarz lists Aviator among its provider games, alongside other Spribe titles. See our Bitstarz review for current terms.
Stake
Stake offers Spribe’s Aviator as a third-party game (see our Stake review), and it also runs its own in-house Crash with a 99% RTP. If you play at Stake, switching from Aviator to Stake Crash cuts the expected cost from about 3% to about 1% of each bet. For more, read our Stake review. For more crash options, see our best crash game casinos and model targets with the crash auto-cashout calculator.
Aviator provably fair verification
Aviator uses Spribe’s provably fair system, which works differently from the single-player seed systems used by most in-house crypto casino games.
The round result combines a server seed generated by Spribe with the client seeds of the first three players who place a bet that round, plus a round counter. Because three independent players contribute seeds, no single party can predetermine the outcome, per Spribe’s provably fair description.
Spribe shows the SHA-256 hash of the upcoming server seed before the round starts, as a commitment. After the round, the server seed and the three client seeds are revealed, so you can check that the hash matches and recompute the result.
Spribe also publishes the algorithm used to convert the seed combination into a crash multiplier. This means anyone with programming knowledge can independently verify past round results. Several third-party verification tools exist that automate this process, allowing you to check hundreds of past rounds in seconds.
The key difference between Spribe's system and the provably fair systems at casinos like Stake or Roobet is that Spribe controls the server infrastructure. In-house crash games at crypto casinos give players more direct access to seed management and rotation. Both systems are legitimate, but the in-house approach is generally considered more transparent because the player has more control over the client seed.
