Aviator is the most-played crash game in the world. A small plane takes off, a multiplier climbs alongside it, and your job is to cash out before the plane flies away and the round ends.
Behind that simple loop sits a 97% RTP, a provably fair system built on three live player seeds, and a probability distribution you can calculate to the decimal. This guide covers all of it: how the game works, the exact maths that governs every round, how to verify a result yourself, where Aviator is and is not available, and the mistakes that cost players money.

The 30-second version
Aviator is a crash game by Spribe with a 97% RTP and a 3% house edge. You place one or two bets, watch a multiplier climb from 1.00x, and cash out before the plane flies away. Every round is provably fair, so you can cryptographically verify the result yourself.

🎮 Aviator in 30 seconds
You place a bet during a short window, then the round starts and a multiplier rises from 1.00x as the plane climbs. Press cash out at any point to win your stake multiplied by the current value. If the plane flies off before you cash out, you lose the bet.
Rounds resolve in roughly 10 to 12 seconds on average, so the game moves at five or six rounds a minute. Aviator’s defining extras are a dual-bet panel that lets you run two bets at once, a live feed of other players’ bets, in-game chat, and free-bet “rain” drops.
💡 Key insight
Four numbers matter more than anything else in this guide: a 97% RTP, a 3% chance of an instant crash at 1.00x, a 48.5% chance of reaching 2x, and a median crash point of 1.94x, below which half of all rounds end. Everything else, the rain, the dual bets, auto cash-out and the provably fair shield, is variance management around those four facts.
🏢 Who makes Aviator: the Spribe profile
Aviator is made by Spribe, a business-to-business games supplier registered as Spribe OU in Tallinn, Estonia, in August 2018, founded and led by chief executive David Natroshvili. Despite the Estonian legal seat, the company operates across several hubs and grew quickly from a small Tbilisi team.

Spribe OU founded in Tallinn
The company is registered in Estonia with David Natroshvili as founder and CEO, starting from a small team in Tbilisi.
Jan
Aviator launches on Adjarabet
The game goes live on the Georgian casino Adjarabet, a date confirmed by court filings in the company’s ongoing trademark litigation.
Mid
Multi-operator rollout
Aviator rolls out to other operators, which is why a secondary “August 2019” date sometimes appears in coverage.
Apr
First crash game licensed in Ontario
Aviator becomes the first crash game licensed in the Ontario, Canada market.
End
Several hundred employees
Spribe scales from its small Tbilisi origins to several hundred staff across hubs including Tbilisi, Tallinn, Warsaw and Kyiv.
Spribe is strictly a business-to-business supplier; it does not run a consumer site, so every “Aviator app” in an app store is an operator’s wrapper rather than an official Spribe product. The game is a pure HTML5 browser product optimised for mobile, which is a large part of why it spread so quickly across emerging markets.
Spribe distributes Aviator through every major casino aggregator and reports licences across many jurisdictions, including the UK Gambling Commission, the Malta Gaming Authority, Romania, Ontario, Sweden, Italy, Switzerland, Colombia, Panama and South Africa. The company has won crash-game supplier awards from bodies such as EGR and SiGMA in recent years.
📝 For the record: Spribe is not the same company as Aviatrix, a separate Cyprus-based developer that also makes a plane-themed crash game and won EGR’s 2024 Crash Games Supplier of the Year. The two are routinely mixed up.
⚡ How Aviator works: complete mechanics
Each Aviator round follows the same loop: a short bet window, the climb, your cash-out, then the crash.
The betting window
A window of roughly 5 seconds in which you set your stake and place a bet.
The climb
The round begins and the multiplier climbs from 1.00x as the plane ascends.
Cash out
You cash out manually, or via a preset auto cash-out target, at any point during the flight.
The crash
The plane flies away at a value that was fixed before the round started, and the round ends. Any bet not cashed out is lost.
Bet limits are set in your base currency, with a minimum of 0.10 and a maximum of 100 per bet, and a maximum win capped at the equivalent of 10,000 per single bet. Local-currency minimums in markets like India or Uganda are just currency conversions of that 0.10 floor.
🔍 Worth noting
The multiplier itself is theoretically uncapped, but the 10,000 maximum-win-per-bet cap is what bites in practice. At a 0.10 stake the cap is only reached at 100,000x, while at a 100 stake it triggers at just 100x. Marketing copy that quotes a “10,000x” or even “1,000,000x maximum” is conflating the payout cap with the multiplier ceiling.
💡 Player protection
If your internet drops during an active bet, Aviator automatically cashes out at the current coefficient. Many competing crash games lack this. It is one of the few places where Aviator’s design clearly favours the player.
📊 Aviator RTP and house edge
Aviator’s default RTP is 97%, which gives a house edge of 3%. That figure is confirmed across multiple independent reviewers and Spribe’s own distribution partners. In the cryptographic generator, the 3% is expressed as roughly a 1-in-33 chance (about 3.03%) that the round instantly crashes at 1.00x.
⚠️ Important
The RTP is almost certainly operator-configurable. While most affiliate copy asserts a “fixed 97%,” game databases such as SlotCatalog explicitly list “RTP ranges” as an Aviator feature, and at least one technical analysis documents alternative 96% and 94% configurations in the wild. Treat 97% as the default and certified ceiling, not a guarantee. Always check the RTP shown in the game’s own info panel on the specific casino you are playing.
A 3% edge places Aviator between European roulette and the average online slot. It is meaningfully worse than the 1% edge on crypto-native crash games from operators like Stake or BC.Game, and worse than optimal-strategy blackjack.
The bottom line: The 3% edge is charged per bet, and at five or six rounds a minute it accumulates quickly even though the headline number looks small.
⚙️ Key features breakdown
Aviator layers four standout features over the basic crash loop: a dual-bet panel, auto cash-out and auto play, a live bet feed with statistics, and in-game chat with a Rain promo.
🔢 Multiplier distribution: the probability table
For a 3% house edge, an Aviator round reaches multiplier m with probability equal to 0.97 divided by m. These are exact arithmetic results rather than estimates, and this distribution is the part of Aviator that no marketing material shows you, despite being the most useful thing on this page to understand.
The distribution is heavily right-skewed. Roughly two-thirds of all rounds end before 1.5x, and about half before 2x, while the spectacular multipliers you see in the highlight feed are vanishingly rare. We prove the full distribution formula, variance and risk of ruin in our crash gambling maths guide.
“In a typical round, the plane is more likely than not to be gone before it doubles your money.”
📝 For the record: Community trackers that log large numbers of rounds report distributions that broadly match this theory, but none are independently auditable, so treat them as indicative rather than proof. Operator-reported record multipliers in the hundreds of thousands or even millions do occur, exactly as the maths predicts at sufficient volume, but payout caps mean players almost never collect the full headline figure.
🛡️ Provably fair: how to verify a round
Aviator’s provably fair system is the most distinctive in the crash category because it pulls entropy from real players. Each round’s crash point is generated from a server seed (the casino’s secret) combined with three client seeds taken from the first three players to bet in that round, plus a round number. Crucially, until those three players place their bets, the outcome literally does not exist anywhere, not even on Spribe’s servers.
The system uses two hash algorithms. A SHA-256 hash of the server seed is published before the round as a commitment, like a sealed envelope. After the round, the result is verified by recomputing a SHA-512 hash from the revealed server seed, the three client seeds and the round number.
📝 For the record: Aviator does not use HMAC, the convention used by Stake, BC.Game and Bustabit, and many SEO articles get this detail wrong.
To verify a round yourself:
Open the round
Find it in My Bets or the Top tab and tap the green shield icon next to the result. This reveals the server seed, the pre-round SHA-256 commitment, the three client seeds, the round number and the resulting multiplier.
Check the commitment
Compute SHA-256 of the revealed server seed. It must match the commitment that was published before the round. This proves the casino did not swap the seed after seeing the inputs.
Check the round hash
Concatenate the server seed, the three client seeds and the round number in the displayed order and compute SHA-512. The result must match the round hash shown.
Reconstruct the multiplier (optional)
The crash point follows the standard 52-bit slice derivation, with a separate modulo-33 branch that forces a 1.00x instant crash about 3% of the time, which is the house edge expressed cryptographically.
Why can the casino not cheat? SHA-256’s preimage resistance means nobody, including Spribe, can later substitute a different server seed and still match the published commitment. Three of the four entropy inputs come from independent players’ browsers at the moment they bet, so they do not exist when the commitment is made. And SHA-512’s avalanche property means even a one-bit change scrambles roughly half the output, making it computationally infeasible to steer toward a chosen multiplier.
🔍 Worth noting
What provably fair does not prove is that the overall RTP matches the advertised return. For that, players rely on RNG certifications from labs such as iTech Labs and BMM Testlabs. And the practical reality is that almost nobody verifies, because the tools are buried and jargon-heavy. The protection only helps if you use it.

📈 Where Aviator is available
Aviator’s commercial mass sits disproportionately in lightly regulated and offshore markets, with a comparatively thin footprint in fully regulated Western jurisdictions. The picture as of mid-2026:
Spribe is also locked in trademark litigation over the Aviator name. In May 2025 the Supreme Court of Georgia ruled that Spribe had registered the Aviator trademarks in bad faith and ordered damages of 330 million euros. Spribe contests this outside Georgia and won a UK High Court interim injunction in 2025, with trial expected in late 2026 or early 2027. The point for players is simply that the company’s claim to have invented Aviator is genuinely disputed in court.
🔍 A note on Spribe’s headline numbers
The eye-watering figures attached to Aviator are worth understanding for context, but every one of them is self-reported by Spribe and has never been independently audited. You will see claims of 77 million monthly active players, more than 400,000 bets per minute, 6,000-plus operator clients, and 160 billion euros wagered in 2025.
🔍 Worth noting
The monthly active player count has escalated from around 12 million in 2023 to 77 million in early 2026, a trajectory fast enough to invite genuine skepticism, and Spribe publishes no methodology for how it defines an active user across thousands of operators. Read these numbers as marketing, not measurement.
The same speed and social features behind that growth have drawn rising scrutiny over player harm. We cover the research evidence, the risk factors and what regulators are doing in a dedicated guide: crash gambling and player harm.
⚠️ Common Aviator mistakes
The costliest Aviator mistakes nearly all stem from misreading the maths or trusting something that cannot be true. These are the ones that drain bankrolls fastest.
⚠️ Scam alert: Apps, Telegram bots and YouTube channels claiming to forecast the next Aviator multiplier with “99% accuracy” are all scams, without exception. The outcome depends on three client seeds that do not yet exist when bets open, and SHA-512 cannot be reversed. These tools exist to funnel deposits and harvest fees, nothing more. We break down the full scam ecosystem in our guide to crash game predictor scams.
The bottom line: With a 3% house edge and no cash-out target that beats it, Aviator cannot be played profitably over the long run. Every cash-out target carries the same minus 3% expected value, so any win is luck, not skill.
