18+ Betting money on cricket carries a direct risk of financial loss, and it can become an addiction. Real-money online gaming is banned across India under the PROG Act 2025, which came into force on 1 May 2026.

If betting is already costing you money you need, or sleep, or people close to you, the free Tele-MANAS helpline is **14416**, and it runs in 20 languages. Our [page on help for gambling harm](/guides/help-for-gambling-harm-india) lists what else exists.

What provably fair actually proves, what RTP means for your money, and why no cash-out strategy changes the expected return of a crash game.

"Fair" in a crash game means two different things, and only one of them is what people are asking about.

- **Provably fair** means you can check afterwards that the round was not altered once bets were placed. That part is verifiable, and the method is explained below.
- It does **not** mean the game is even money. Every version runs a house edge, and that edge is the whole business model.
- No, a person is not watching your account and pulling the plug. The round is generated before you bet — which is exactly what the verification proves.
- No cash-out strategy changes the maths. Cashing out at 1.5× and at 10× have the same expected return; only the shape of the losses changes.

This page explains the arithmetic. It is not a guide to playing, and nothing here is a strategy that wins. If you are looking for that, the honest answer is in the [responsible gaming](/responsible-gaming) section instead.

## Two different questions get the same word

When people ask whether a crash game is fair, they mean one of two things. The first is procedural: is the round rigged against me personally, once the operator sees my stake? The second is economic: over time, is this a game I can beat? The first can be checked with a cryptographic proof and a properly implemented game passes it; the second is settled by arithmetic, and the answer is no. Conflating them is why the question never gets settled.

## How provably fair actually works

The mechanism is a commitment scheme, and it is older than online gambling. Its purpose is to let someone prove they decided something in advance without revealing what they decided.

Before a round, the operator generates a secret value — the server seed — and publishes its cryptographic hash. A hash is a one-way fingerprint: you cannot work backwards from it to the seed, but any given seed produces one and only one hash. Publishing the hash is a public commitment: whatever the seed is, it is fixed now.

Your side contributes too. A client seed, drawn from the players in the round or from your own browser, is combined with the server seed, so neither side can steer the result alone.

After the round the operator reveals the server seed. You hash it yourself and compare it with the hash published beforehand. If they match, the seed was not swapped mid-round; running the seeds through the published formula reproduces the multiplier the game showed.

## What the check proves, and what it does not

This is where most explanations stop, and it is the part worth being precise about.

| The verification proves | It does not prove |
|---|---|
| The round was decided before you bet | That the odds are in your favour |
| The result matches the published formula | That the formula's house edge is small |
| The operator did not swap the seed mid-round | That the app you are using is the real game |
| This one round was not manipulated | Anything about the long-run distribution |

That last row matters most. A provably fair scheme verifies individual rounds against a stated formula, and says nothing about whether that formula returns 97 paise per rupee or 80. Both can be provably fair. The word "fair" is doing a lot of quiet work by covering both.

## RTP and the house edge

RTP means return to player: the share of everything staked that the game pays back across a very large number of rounds. The remainder is the house edge, and it is not a fee added on top — it is built into the multiplier distribution itself.

Providers publish an RTP figure for each game, and it is the number to look for before anything else. Take a game stated at 97% RTP. That means a 3% house edge, and it means the following, none of which is hidden or disputed:

| You stake | Expected return at 97% RTP | Expected loss |
|---|---|---|
| ₹100 once | ₹97 | ₹3 |
| ₹100 a hundred times | ₹9,700 | ₹300 |
| ₹100 a thousand times | ₹97,000 | ₹3,000 |

The more rounds you play, the more reliably the outcome converges on that 3%. Short sessions are noisy and can easily end up ahead; that noise is what makes the game playable, and it is not an opportunity. Our guide to [expected value](/guides/expected-value-explained) works through the same arithmetic in a betting context, and [the overround](/guides/what-is-overround) is the identical idea expressed in odds rather than percentages.

Read the provider's own stated RTP for the specific game and version, not a figure quoted by a site that wants you to play: different builds of similar-looking games need not carry the same number.

## Why cash-out strategies do not change the maths

This is the question behind most searches, so here is the demonstration rather than an assertion.

In an idealised crash game with RTP *r*, the chance of the round reaching a multiplier *m* is approximately *r* divided by *m*. Set your auto cash-out at *m* and your expected return per rupee staked is the multiplier times the chance of reaching it: *m* × (*r* / *m*) = *r*. The *m* cancels. Whatever you pick, you are left with *r*.

| Auto cash-out | Chance of reaching it | Expected return per ₹100 |
|---|---|---|
| 1.2× | about 81% | ₹97 |
| 1.5× | about 65% | ₹97 |
| 2× | about 48% | ₹97 |
| 5× | about 19% | ₹97 |
| 10× | about 10% | ₹97 |
| 50× | about 2% | ₹97 |

The right-hand column is the whole answer. A cautious player cashing out at 1.2× wins four rounds in five and still loses three rupees per hundred over time. A player waiting for 50× loses the same three rupees, arriving via long droughts and occasional large wins. The strategies differ in variance — how bumpy the ride is — and not in destination.

This is the same structure as any market with a built-in margin, set out for bookmaker prices in [how bookmakers set odds](/guides/how-bookmakers-set-odds).

Two caveats so this is not overstated. The formula above is the idealised model; real implementations differ in detail, including how they handle an immediate crash at 1.00×, and the provider's own paytable is authoritative. And the percentages in the middle column are rounded. The right-hand column, though, does not depend on those details — it follows from the RTP alone.

## Doubling after a loss is the oldest of these

The most common "system" is to double the stake after each loss so that one win recovers everything. It is worth walking through because it fails for reasons that are easy to check.

Start at ₹100 and double after each loss: 100, 200, 400, 800, 1,600, 3,200, 6,400. Seven losses in a row and you have staked ₹12,700 chasing a ₹100 profit. At an even-money cash-out point, seven losses in a row happens about once in every hundred sequences — not often, but not rare either if you play regularly.

Two things stop it. Every game has a maximum stake, so the doubling cannot continue indefinitely, and your own balance runs out before that limit does. The strategy converts a small steady loss into a long series of small wins punctuated by one very large loss; the expected value is unchanged, because it was never the sequence of bets that set it.

## Is the game controlled by a person?

Not in the sense the question usually means. Nobody is watching your balance and deciding when to crash the round, and in a properly implemented provably fair game this is not a matter of trust — it is the thing the hash commitment rules out. The round was fixed before you staked, and you can check that yourself after the fact.

There is a second answer worth knowing, because it does not depend on trusting the operator's own description at all. Where a game is licensed in a regulated market, a regulator writes down what it is allowed to do. The UK Gambling Commission's technical standards for remote gambling put it in one line: Adaptive behaviour (that is, a compensated game) is not permitted. The same standard adds that random numbers are to be used in the order in which they are received and they may not be discarded due to adaptive behaviour.

In plain terms, a licensed game may not adjust its odds in response to how much you have staked, how much you have won, or how long you have been playing, and it may not quietly throw away a result it does not like. That is the specific accusation behind "is it controlled by a person", and in a regulated market it is prohibited rather than merely denied. The full text is [RTS 7 in the remote technical standards](https://www.gamblingcommission.gov.uk/standards/remote-gambling-and-software-technical-standards/rts-7-generation-of-random-outcomes).

Two limits on how far that carries. It binds operators licensed in that market, and a reader in India is very often not playing on one — so the rule describes what a properly regulated version must do, not a guarantee about the app in front of you. And it governs the game's behaviour, not its generosity: a compensated game is banned, a game with a large house edge is not.

What *is* decided by people is everything upstream: the RTP the provider builds into the distribution, the maximum stake, the payout limits. Those are commercial decisions, set in advance, published, and applied to everyone equally. That is a very different thing from an operator intervening in your round, and the two get confused constantly.

## The real risk is the app, not the algorithm

For a player in India the practical danger is rarely the mathematics of the original game, which is documented and checkable. It is that the thing you have installed is not that game.

Crash games are widely cloned. A copy can look identical, use the same name and artwork, and implement none of the verification — or show a verification panel that checks nothing. If there is no published hash before the round, no revealed seed after it, and no stated RTP, then nothing on this page applies, because there is nothing to reason about. Our companion piece on [what the game is and what can actually be verified](/blog/what-is-aviator-game) works through what the public record does and does not establish, and our checklist for [spotting a fake app](/guides/how-to-spot-a-fake-cricket-app) covers the install itself.

If the reason you are reading this is that the losses have stopped feeling like entertainment, that is worth taking seriously on its own terms. Our [responsible gaming page](/responsible-gaming) lists Indian helplines and the tools for setting limits or self-excluding.

## Where to check this yourself

Three things are worth verifying at first hand rather than taking from any site, including this one. The provider's own page for the specific game, which states the RTP and the maximum multiplier. The game's own provably fair panel, which should show the hashed server seed before a round and let you reveal and verify the seed afterwards. And the operator's terms, for stake and payout limits.

If any of the three is missing or vague, that absence is itself the finding: a genuinely provably fair game has every incentive to make the verification easy to find.

Beyond the game itself, two public records are free to read and take about five minutes:

- The [UK Gambling Commission public register](https://www.gamblingcommission.gov.uk/public-register/businesses) lists every licensed supplier and operator, the licences each holds, the dates, and any regulatory action taken against them. A supplier that is not on it is not licensed there, and one that is will show its history whether flattering or not.
- [RTS 7](https://www.gamblingcommission.gov.uk/standards/remote-gambling-and-software-technical-standards/rts-7-generation-of-random-outcomes) sets out what a licensed game's random number generation must satisfy, including the ban on adaptive behaviour quoted above, and the requirement that games and RNGs are tested by an [approved test house](https://www.gamblingcommission.gov.uk/licensees-and-businesses/guide/page/games-test-reports-remote-gambling-and-gambling-software).

Neither register covers India, and neither tells you whether real-money play is lawful where you are. That question is separate and we deal with it in [the legal position on online betting in India](/legal/online-betting-law-india).

## Questions people ask

### Is the Aviator game fair?

In the procedural sense, a properly implemented version is: the round is committed to before you bet and you can verify it afterwards. In the economic sense it is not even money — it runs a house edge, published as an RTP figure, and that edge applies to every round regardless of how you play.

### What is the algorithm behind the game?

A secret server seed is hashed and published before the round, combined with a client seed, and run through a published formula to produce the multiplier. Revealing the seed afterwards lets anyone confirm the result matches the commitment made in advance.

### Is there a strategy to win at a crash game?

No. Every auto cash-out point gives the same expected return, because the multiplier and the chance of reaching it move in opposite directions and cancel out. Strategies change how volatile the results are, not the long-run outcome.

### Can the operator see my bet and crash the round?

Not in a correctly implemented provably fair game — the round is committed to before bets are accepted, and the published hash makes a later change detectable. If a version offers no such verification, there is no basis for that assurance.

### Does doubling my stake after a loss work?

No. Maximum stake limits and your own balance both run out before the sequence recovers, and the expected value is unchanged either way. It converts a steady small loss into occasional very large ones.
