Run up to 100,000 spins — verify with real-time charts & Chi-Square proof that every spin is 100% fair.
Every spin on SpinAWheel.net is powered by your browser's built-in Cryptographically Secure Pseudo-Random Number Generator (CSPRNG) — the same standard used in banking and encryption. Results are impossible to predict or manipulate.
The winner is determined instantly the moment you click spin. The animation is purely visual — the wheel decelerates to land on the already-chosen spot. The audit simulation below uses the same secure engine to prove every segment has a mathematically equal chance. Learn more on our About page.
The audit runs thousands of simulated spins using the same cryptographically secure random number generator that powers our live wheel spinner. It then checks whether the distribution of wins across all segments is statistically consistent with a perfectly fair wheel.
The Chi-Square Goodness-of-Fit test is a standard scientific method used to determine if observed outcomes match expected probabilities. A p-value above 0.05 means there is no statistically significant bias — the results are consistent with a truly fair and random distribution.
Every segment on the wheel has an exactly equal probability of being chosen. Because randomness is inherently unpredictable, you may occasionally see one segment win slightly more than others in a small sample — but with 10,000+ spins, the distribution will always converge to near-perfect equality.
