UltraGambler earns a commission if you sign up through some links on this page. It never changes our ratings. 18+. How we make money

Quick answer: Crash games are simple: a multiplier climbs from 1.00x and you must cash out before it “crashes”. The best-known are Aviator, JetX and Spaceman, with RTPs of about 96.5% to 97%. Our top pick for crash games is 1win (9.9/10), which offers Aviator, JetX and its own Lucky Jet and paid our crypto withdrawal in 15 minutes. No cash-out strategy beats the house edge, so treat crash games as entertainment with a set budget.

How do crash games work?

A multiplier rises from 1.00x and crashes at a random point that is fixed before the round starts. Cash out before the crash and you win your stake times the multiplier; miss it and you lose the stake.

  • You place a bet before the round starts. Most games let you place two bets at once.
  • A multiplier starts at 1.00x and rises.
  • At a random point, decided before the round began, it crashes.
  • If you cashed out before the crash, you win your stake times the multiplier. If not, you lose the stake.
  • Auto cash-out lets you set a target, such as 2x, so the game cashes out for you.

Aviator is the game that made crash popular. It uses provably fair seeds from the server and the first three players each round; read our Aviator guide, which also explains how to play it at 1win. JetX by SmartSoft Gaming is similar, with two bets and auto-collect. Spaceman by Pragmatic Play adds a “Cashout 50%” button to bank half a win and let the rest ride, and caps wins at 5,000x. Lucky Jet is 1win’s own crash game; see our Lucky Jet guide.

Crash game strategy: what the maths says

At a 97% RTP, the chance of the multiplier reaching any target is roughly 97% divided by the target. So 2x happens about 48.5% of the time, 10x about 9.7% and 100x about 1%. Multiply the chance by the payout and you get the same answer every time: you keep about 97% of what you bet, on average. That is why no cash-out target changes your expected result.

Cash-out targetChance of reaching it (97% RTP)What it feels like
1.5xAbout 65%Frequent small wins, occasional losses that wipe out several wins
2xAbout 48.5%Roughly a coin flip, slightly worse
10xAbout 9.7%Long losing runs are normal
100xAbout 1%Very rare; a budget can run out first

Martingale (doubling after every loss) fails in crash for the same reason it fails at roulette: a run of eight losses at 2x needs a bet 256 times your first stake to recover one unit, and table limits or your budget usually stop you first. Read more in our betting strategy guide.

How long can a crash losing streak last?

Much longer than most players expect at high targets: chasing 100x, you have about a 61% chance of losing 50 rounds in a row. We worked out the chance of a losing run at each target in a 97% RTP crash game (the chance of missing the target, multiplied by itself once per round):

Cash-out targetChance of losing a round10 losses in a row20 losses in a row50 losses in a row
2x51.5%About 0.13%Under 0.01%Practically never
10x90.3%About 36%About 13%About 0.6%
100x99.0%About 91%About 82%About 61%

At €1 a round, someone chasing 100x will lose €50 before their first win in about 6 of every 10 sessions. Size your bets so your budget covers the losing runs your target makes likely, or pick a lower target.

Tips for playing crash games safely

  • Set a budget and a time limit before you start, and stop when you hit either.
  • Use auto cash-out so you don’t make emotional decisions mid-round.
  • Ignore “predictor” apps and signal groups: they can’t know a crash point in advance. See our Aviator predictor warning.
  • Check whether the game is provably fair and how to verify it. Our provably fair guide explains how.
  • If crash games stop being fun, take a break. Our responsible gambling page has help and warning signs.

How we checked this

  • Payout times come from our own test withdrawals: 1win and FortuneJack, both in June 2026.
  • Aviator at 97% RTP: SlotCatalog and Tuttosport.
  • JetX at 97% RTP, released 2019, with wins recorded up to 25,000x: SlotCatalog and SiGMA.
  • Spaceman at 96.5% RTP with a 5,000x cap, launched March 2022: SlotCatalog and The Spike. Pragmatic Play’s own page lists 95%, so check the info screen at your casino.
  • Lucky Jet at 97% RTP, released 2021: SlotCatalog and Film Daily.
  • The cash-out chances, the losing-streak table and the Martingale example are our own maths (a losing streak’s chance is the chance of missing the target raised to the number of rounds): chance of reaching a target is about RTP divided by the target, and eight doubled losses need a stake of 2 to the power 8, or 256 units.

Last checked: 10 November 2026, when we worked out the chance of 10, 20 and 50 losses in a row at 2x, 10x and 100x targets ourselves. On 12 October 2026 we worked out the cash-out chances and checked each game’s RTP against at least two independent sources; that check found Pragmatic Play’s own page lists Spaceman at 95%.

Crash gambling FAQs

What is a crash gambling game?

A game where a multiplier rises from 1.00x until it crashes at a random point. You win if you cash out before the crash.

Which crash game has the best RTP?

Aviator, JetX and Lucky Jet are listed at 97%, slightly above Spaceman at 96.5%.

Is there a winning crash strategy?

No. The house edge applies to every cash-out target, so no strategy changes the expected return. Strategies only change how often you win and how big the swings are.

How many times in a row can you lose at crash?

A lot, at high targets. In a 97% RTP game, aiming for 10x gives about a 36% chance of 10 straight losses, and aiming for 100x gives about a 61% chance of 50 straight losses.

Are crash games rigged?

Reputable crash games use certified or provably fair systems that let you check results. That proves fairness, not that you will win.

Where can I play crash games?

Our top pick is 1win (9.9/10), which offers Aviator, JetX and Lucky Jet. Check that online gambling is legal where you live first.


Important: check your local laws before you play

Online gambling laws differ from country to country, and in some places it is restricted or not permitted at all. Check that online gambling is legal where you live and that the casino accepts players from your country. You must be 18 or older (or the legal gambling age in your country, if higher). Only gamble with money you can afford to lose.
