Aviator and Crash Games Explained

Updated 11 October 2026 · 7 min read · 18+ · How this site is funded

In Aviator and other crash games a multiplier rises until it crashes at a random moment, you win only if you cash out first, and the studios publish returns of 95% to 97% for the titles covered here.

Key facts

  • A crash round starts a multiplier that keeps growing and can stop at any moment. Cashing out before it stops pays your stake times the multiplier on screen; staying in when it stops loses the stake.
  • Published returns: Aviator 97% and Mines 97% (both Spribe), Spaceman 95% (Pragmatic Play). SmartSoft does not state the return of JetX on its game page.
  • Spribe says each Aviator round can be checked afterwards against cryptographic seeds. That is a check of a finished round, not a way to see the next one.
  • Decode (BOOM), an Indian publication, reported on 27 March 2025 at least 18 Telegram groups where scammers promised to double people’s money by playing Aviator for them.
  • The Australian Communications and Media Authority (ACMA) lists casino-style games among the online services that are illegal to offer to people in Australia.

What a crash game is

A crash game is a casino game built on one number: a multiplier that rises from the start of the round until it crashes, with the player deciding when to take the money. Spribe describes Aviator as “an increasing curve that can crash anytime”: “When round starts, a scale of multiplier starts growing. Player must cash out before lucky plane flies away.”

Pragmatic Play gives the same rule for Spaceman: “Press the cashout button before he crashes to apply the current multiplier to your bet and win.” The theme changes from game to game, a plane in Aviator, a jet in JetX, a spaceman in Spaceman; the mechanic does not. There are no reels or paylines, which is why crash games sit apart from pokies.

Aviator: Spribe’s crash game

Aviator is the crash game made by Spribe, a studio founded in August 2018; its company history says: “January 2019 — Our flagship game - Aviator, goes live”. Spribe publishes a return to player (RTP) of 97%, meaning the game is built to pay back A$97 of every A$100 staked over a very large number of rounds and keep about A$3.

Spribe calls Aviator a “social multiplayer game”. Players in the same round share an in-game chat, Live Bets (“Everyone can see how much other players are betting and winning.”), Live Statistics and Rain Promo, which hands out free bets in the chat. Other players’ wins shown in Live Bets have no bearing on the result of your next round.

The UK Gambling Commission’s public register lists Spribe OÜ (account 57302) with a gambling software licence, active since 8 December 2020, checked 11 October 2026. Spribe does not state whether casinos can run Aviator at a return other than 97%.

Other crash games: JetX and Spaceman

JetX and Spaceman are two other crash games, and only Spaceman’s studio publishes an RTP. SmartSoft says JetX, “Launched in 2018”, “was the first flying crash game and set the direction for the crash games category”; that is the studio’s own claim. JetX allows up to four bets at once and offers “Advanced Autoplay and Auto Cashout”.

Pragmatic Play’s Spaceman has an RTP of 95%, two points below Aviator: on A$100 of stakes it is built to keep about A$5 instead of A$3. It offers auto-cashout, which takes the money at a multiplier you set in advance, and a 50% auto-cashout option.

Figures are the studios’ published values, checked 11 October 2026. Other sites quote an RTP for JetX; SmartSoft’s own page does not, so we leave it blank. Bet limits are not on any of the three studio pages and depend on the casino.

Provably fair: what it proves and what it does not

Provably fair, as Spribe describes it, lets a finished round be checked against the seeds that produced it; it does not predict rounds or improve the return. Spribe says its games use “cryptographic technology called ‘Provably Fair’”: a server seed from the operator and client seeds from players are combined and hashed with SHA512, and “Fairness of each game round can be checked and verified.”

Because the crash point is calculated from seeds that include those of the players in the round, it cannot be known before the round starts. That is our reading of Spribe’s description, not a Spribe statement. We have not tested the verification ourselves.

What provably fair does not cover: it does not change the 97% return, it does not show which version a casino has installed, and it gives no protection if a casino refuses to pay out.

“Predictors” and Telegram signals

Apps and channels selling Aviator “predictions” or “signals” are presented as a way to beat the game. On 27 March 2025 Decode (BOOM), an Indian publication, wrote: “Telegram, meanwhile, has at least 18 groups where scammers promise to double your investment by playing on your behalf.” We found no warning on predictors from a regulator or from Spribe.

The section above explains why a prediction tool has nothing to work with: Spribe says the operator generates the server seed and publishes its hash before the round starts, and the players’ seeds are combined with it when the round starts, so on Spribe’s description the result cannot be known before the round begins. In our reading, a “signal” that seems to work for a few rounds is chance.

We do not link to predictor apps, signal channels or Aviator APK download sites. If you want to see how a game behaves without money, our free pokies guide explains how free and demo play works and what it does not show. For the peg-board game often listed next to Aviator, see our Plinko guide.

Mines, the neighbouring format

Mines is not a crash game but works on the same cash-out choice, and Spribe publishes the same 97% return for it. Spribe’s description: “there are stars and land mines hidden on the field. Goal is to open as many stars as possible and don’t blow up on the mine. With each opened star winnings increase. Player can cash out after each successful guess and take his winnings.”

Each pick raises the possible payout and puts the whole stake at risk again. Spribe’s game page does not state the size of the field or how many mines it holds.

Gambling or skill

Crash games are gambling: the crash point is random, and the player’s only decisions are the stake and the moment to cash out. Spribe publishes one return for Aviator, 97%, and describes no way to raise it.

Cashing out early wins more often and pays less; waiting pays more and loses more often. Neither choice is described by the studios as changing the game’s return. ACMA, for its part, lists “casino-style games” among illegal online services without separating games of choice from games of pure chance.

Real-money crash games are online casino games, and ACMA says “The Interactive Gambling Act 2001 makes it illegal for gambling providers to offer some online services to people in Australia”, with online casinos among the banned services.

For the player, ACMA names two risks: “If you use an illegal service, Australian regulators will not be able to help you if … the service provider withholds your winnings”, and blocked sites mean “you may not be able to log in and access your existing account.” ACMA asks internet providers to block sites offering online casinos and online slot machines to people in Australia.

The Interactive Gambling Amendment (Gambling Reform) Bill 2026 passed on 19 August 2026; ACMA says most of the reforms commence on 1 January 2027. Our page on Australian online gambling law covers the detail.
