Crash games such as Aviator, JetX, Spaceman, Lucky Jet and crypto crash titles all revolve around the same betting question: what is the chance that the round reaches your target multiplier before it crashes?
This Crash Game Probability Calculator estimates the win probability, loss probability, expected value and streak risk for any cashout target. Enter a multiplier, choose the game RTP or house edge, and the tool shows the long-run math behind that cashout point.
Important: this is a probability and variance calculator. It is not a predictor. It cannot know the next crash point, and it does not use secret seed data. For completed-round hash verification, use the Provably Fair Verifier. For Aviator-specific SHA-512 verification, use the Aviator Provably Fair Verifier.
Quick Answer: Crash Game Probability Formula
For the usual crash-game probability model, the chance of reaching a target multiplier is:

| Question | Can this calculator answer it? |
|---|---|
| What is the chance of reaching 2.00x? | Yes. |
| What is the chance of a 5-loss streak at 2.00x? | Yes. |
| What is the expected value per $1 bet? | Yes. |
| Which cashout target has lower variance? | Yes. |
| What will the next round crash at? | No. |
| Can a predictor app beat the algorithm? | No. |
How to Use the Calculator
This tool calculates win probability at any target multiplier, accounting for the selected RTP or house edge.
- Target multiplier: enter your planned cashout point, such as 1.50x, 2.00x, 5.00x or 10.00x.
- Platform / RTP: choose a preset or enter custom RTP/house edge if the game rules show a different value.
- Analyze the result: review win probability, loss probability, expected value and outcome distribution.
- Check streak risk: use the streak tab to estimate how often losing or winning streaks occur.
Reading the Output
- Win probability: calculated as P = RTP ÷ Multiplier. For a 97% RTP game at 2.00x, that is 97% ÷ 2 = 48.5%.
- Expected value per bet: the mathematical average over many rounds. A negative EV reflects the house edge.
- Outcome distribution: shows how often wins and losses are expected across a sample of rounds.
- Streak probability: estimates the chance of repeated wins or losses at the selected target.
Crash Game Probability Formula
For the standard crash-game distribution, the probability of reaching multiplier X is:
Example for a 97% RTP game at a 2.00x cashout target:
97% ÷ 2.00 = 48.50%
This means the round is expected to reach 2.00x about 485 times per 1,000 rounds. It also means the loss probability is about 51.50%.
Why 2.00x Is Not a 50/50 Bet
A common mistake is to treat 2.00x as a coin flip. It is close, but not exactly fair because the house edge shifts the probability below 50%.
| RTP | 2.00x win probability | 2.00x loss probability | Expected loss per $100 wagered |
|---|---|---|---|
| 99% | 49.50% | 50.50% | $1.00 |
| 97% | 48.50% | 51.50% | $3.00 |
| 96% | 48.00% | 52.00% | $4.00 |
Probability Table: 97% RTP Example
| Target Multiplier | Win Probability | Lose Probability | Expected Wins per 1,000 Rounds |
|---|---|---|---|
| 1.10x | 88.18% | 11.82% | ~882 |
| 1.50x | 64.67% | 35.33% | ~647 |
| 2.00x | 48.50% | 51.50% | ~485 |
| 3.00x | 32.33% | 67.67% | ~323 |
| 5.00x | 19.40% | 80.60% | ~194 |
| 10.00x | 9.70% | 90.30% | ~97 |
| 20.00x | 4.85% | 95.15% | ~49 |
| 100.00x | 0.97% | 99.03% | ~10 |
Losing Streak Risk
Crash games feel streaky because each round is independent but the loss probability can be high, especially at larger targets.
For a fixed cashout target:
P(Losing Streak) = Loss Probabilityn
Example: at 2.00x on a 97% RTP game, the loss probability is 51.50%. The chance of five consecutive losses is:
0.5155 = 3.62%
That may sound low, but across many sessions and many players, streaks are normal. A losing streak is not evidence that the game is “due” to pay. It is part of the distribution.
Why Martingale Fails
Doubling after each loss does not change expected value. It only shifts risk into rare but large drawdowns. The longer the streak, the faster the required next bet grows.
| Losses in a row | Next Martingale bet size | Total amount risked so far |
|---|---|---|
| 3 | 8x base bet | 7x base bet |
| 5 | 32x base bet | 31x base bet |
| 8 | 256x base bet | 255x base bet |
| 10 | 1,024x base bet | 1,023x base bet |
Instant 1.00x Rounds
Many crash games include an instant crash or equivalent edge mechanism. This is one way the house edge appears in the distribution. In a 97% RTP example, roughly 3% of theoretical outcomes are equivalent to an immediate loss before any normal cashout target can be reached. In a 99% RTP example, the equivalent edge is roughly 1%.
| RTP | House Edge | Approximate Edge Cost per $100 Wagered |
|---|---|---|
| 99% | 1% | $1.00 |
| 97% | 3% | $3.00 |
| 96% | 4% | $4.00 |
The exact implementation can vary by provider. Some systems use an explicit instant-crash rule; others embed the RTP factor directly into the multiplier formula.
Need the Hash-to-Multiplier Formula?
This page focuses on crash game probability, RTP, cashout targets and streak risk. The technical hash-to-multiplier explanation has been moved to a dedicated guide.
Read the Aviator Hash to Multiplier guide for the common 52-bit crash-game model, SHA-512 hash slicing and why SHA-256 commitments cannot predict future rounds.
RTP Comparison by Platform Type
Always verify the actual RTP in the game rules before playing. Providers and casino integrations can change settings, and not every site displays the same version of a game.
| Game family / platform type | Typical RTP band | Expected loss per $100 wagered | Comment |
|---|---|---|---|
| High-RTP crypto crash games | ~99% | ~$1.00 | Lower long-run cost, same variance problem. |
| Aviator-style 97% RTP games | ~97% | ~$3.00 | Common in branded crash titles. |
| Unknown scripts / unverified versions | Varies | Unknown | Check rules, RTP and verification details before playing. |
Lower house edge means slower expected bankroll drain. It does not guarantee profit, and it does not reduce short-term volatility.
1xBet / Lucky Jet Calculator: What Can Be Calculated
Many searches for “1xBet crash calculator” or “Lucky Jet algorithm calculator” are really asking for prediction. Prediction is not possible from public information. What can be calculated is:
- Probability of reaching a target multiplier.
- Expected value from a given RTP.
- Loss-streak probability.
- Expected cost of the house edge.
If you use a 97% RTP assumption, the same probability table applies: 2.00x is about 48.5%, 5.00x is about 19.4%, and 10.00x is about 9.7%.
BC.Game / Stake-Style 99% RTP Example
For a 99% RTP game, the formula is still:
P(Win) = RTP ÷ Multiplier
| Cashout Target | 97% RTP | 99% RTP | Difference |
|---|---|---|---|
| 1.50x | 64.67% | 66.00% | +1.33 percentage points |
| 2.00x | 48.50% | 49.50% | +1.00 percentage point |
| 5.00x | 19.40% | 19.80% | +0.40 percentage points |
| 10.00x | 9.70% | 9.90% | +0.20 percentage points |
The difference looks small per round, but over high volume it matters. At $10,000 total wagered, a 99% RTP game has about $100 expected loss, while a 97% RTP game has about $300 expected loss.
Warning: Predictor Apps and Signal Bots
Any app, Telegram bot or website claiming to predict the next crash point should be treated as a scam unless it provides verifiable, public, independently auditable proof. In a properly implemented provably fair system, hidden seed data is not available before the round is resolved.
Common Scam Patterns
| Claim | Why it is unreliable |
|---|---|
| “85% accurate predictor” | Usually random numbers, cherry-picked screenshots or fake demo wins. |
| “Telegram signal group” | Wins happen by chance, losses are hidden or explained away. |
| “Algorithm cracked APK” | High risk of malware, keyloggers or credential theft. |
| “Guaranteed safe cashout” | No cashout point removes the house edge or variance. |
The honest use of math is bankroll planning, risk control and understanding variance. It is not future-round prediction.
The Only Honest Approach
- Understand the math: use this calculator to know the actual long-run odds.
- Set a bankroll limit: decide in advance what you can afford to lose.
- Use realistic cashout targets: lower targets reduce variance but do not remove negative EV.
- Accept the house edge: over enough rounds, RTP drives the expected result.

Frequently Asked Questions
Is there an Aviator predictor app that works?
No. Any app or bot claiming to predict the exact next outcome should be treated as a scam. A probability calculator can show long-run odds, but it cannot reveal future crash points.
What is the crash game probability formula?
The usual probability model is P(Win) = RTP ÷ Target Multiplier. For a 97% RTP game at 2.00x, the probability is 97% ÷ 2 = 48.5%.
How does Aviator provably fair verification work?
Aviator verification uses a server seed, client seeds and a SHA-512 round hash shown in the game’s fairness panel. The exact verification flow is handled on the dedicated Aviator Provably Fair Verifier page. This calculator focuses on RTP, cashout probability and streak risk.
What is the RTP of Aviator and other crash games?
Aviator-style games are often listed around 97% RTP, while some crypto crash titles are listed around 99% RTP. Always check the actual game rules because RTP can vary by provider and platform.
Why is 2x not a 50/50 chance?
Because of the house edge. With 97% RTP, P(Win at 2x) = 97% ÷ 2 = 48.5%, not 50%. With 99% RTP, it is 49.5%.
What is the best strategy for crash games?
No strategy removes the house edge. Lower cashout targets reduce variance and create more frequent small wins. Higher targets create rare large wins and deeper losing streaks. Expected value is still driven by RTP.
Is Aviator rigged or fair?
Legitimate implementations provide a provably fair verification flow. That lets players check completed-round seed and hash data. It does not mean the game has positive expected value.
Can a crash game algorithm be hacked?
No credible public method can hack or predict a properly implemented provably fair crash game. Claims of hacks, bots or guaranteed predictors should be treated as scams.
Where can I learn about hash-to-multiplier math?
Use the Aviator Hash to Multiplier guide. It explains the common 52-bit crash-game model, the difference between SHA-256 commitments and SHA-512 round hashes, and why hash formulas verify completed rounds rather than predict future results.
How do I verify a crash game round was fair?
Open the game’s fairness panel and copy the revealed server seed, client seed or client seeds, nonce or round number, and expected hash. Then use the platform’s documented verification method. For generic seed/hash checks, use the Provably Fair Verifier. For Aviator-specific SHA-512 verification, use the Aviator Provably Fair Verifier.
Responsible gambling notice: crash games are high-variance gambling products. Probability tools can explain risk, but they do not predict outcomes or create profit. Never wager more than you can afford to lose.
Is this simulator actually accurate to real casino algorithms like Stake or BC.Game? I feel like I’m winning way more here than I do when playing with real money. Does it simulate the house edge properly?
Hi Liam! Yes, the math behind our Crash Simulator mimics the standard HMAC_SHA256 algorithm used by major crypto casinos. However, remember that ‘Random’ means anything can happen in the short term.
In real casinos, there is usually a 1% to 4% House Edge (often caused by the game instantly crashing at 1.00x). Our simulator includes this probability to ensure your strategy testing is realistic. If you are winning more here, it might just be a lucky variance streak, which is exactly why testing here first is safer than testing with your wallet!
I tried the Martingale strategy (doubling bet after loss) aiming for 2.0x. It worked for 500 rounds, but then I got a streak of 12 crashes under 2.0x and lost everything. Is there a bug in the randomizer?
Can I see the server seed or client seed used for these results? I want to verify that the crash points are pre-determined and not reactive to my bets.
I’m trying to catch a 100x multiplier. How often does that actually happen? I’ve been clicking for 20 minutes and the highest I saw was 45x.
