Free Roulette Simulator
Run independent random spins in your browser. No result is sent to a server and no real money is involved.
How to use the simulator
Select a European or American wheel, choose an even-money wager and enter a hypothetical stake. A single spin is useful for exploring the interface. A batch of hundreds or thousands of spins is more useful for observing variance.
The simulator uses the browser’s random-number generator. It is not connected to a casino and does not reproduce a particular dealer, wheel or certified gaming RNG. Each generated pocket is independent of the previous pocket.
How to read short-term results
A profitable batch does not prove that the selected bet has an advantage. On a European wheel, red wins on 18 pockets and loses on 19, including zero. Its expected result is therefore negative even though many individual sessions finish ahead. Increase the sample size and repeat the batch rather than selecting only a favourable run.
Useful experiments
- Compare 100 spins with 10,000 spins.
- Record the largest gap between red results.
- Run identical stakes on European and American wheels.
- Compare the observed hit rate with 18/37 or 18/38.
