Crash Game Maths Tools
Three small calculators to check the arithmetic behind crash rounds. Educational only: no predictions, no strategy, no guaranteed profit.
These tools run entirely in your browser. They do not connect to any game, account or wallet, and nothing you type is sent anywhere. They exist to make three ideas concrete: how a payout is calculated, how independent rounds with a house edge behave over many trials, and what a hash commitment can and cannot prove.
No tool can tell you where the next round will end. If a site claims otherwise, read our crash game myths guide.
For decimal odds and forecast uncertainty, use the Match Insights probability tools. This is a separate research site under common ownership, not a betting service. For a per-ball cost example, see the Fish & Chips budget calculator (separate site, common ownership, 18+). It cannot place a bet or access a wallet.
Tool 1
Payout and profit explainer
Gross return is stake multiplied by the cash-out multiplier. Profit subtracts the stake. If the round crashes before you cash out, gross is zero and the whole stake is lost.
Tool 2 · Toy model
Independent-round crash simulator
This is a TOY model with a simple seeded generator. It is not any real game's RNG and it does not predict real rounds. Every round is independent: each has the same win chance regardless of earlier results.
Tool 3
SHA-256 commitment checker
Checks whether SHA-256 of a revealed value equals a published commitment. A match proves only that this value was committed. It does NOT verify a round outcome, a crash multiplier, a return-to-player rate, fairness of the game or a licence.
What these tools do not do
The simulator uses a simplified win chance of (1 minus house edge) divided by the cash-out target. Real games publish their own rules and may differ. A positive toy result is luck within the model, not a method. The commitment checker confirms a hash only. For limits on time and spending, see bankroll and risk and responsible gaming. 18+ only.
