Roulette Wheel Simulator
Spin a European or American wheel up to 200,000 times in a second and look at the distribution, hot and cold numbers and streaks.

Change any value — results update instantly.
Bars show hits per pocket in number order (0 first, 00 last on the American wheel). Run 100 spins and the "hot" numbers look meaningful; run 100,000 and they flatten out — that is the whole story of hot-number strategies.
How to use the wheel simulator
Choose European or American.
Enter the number of spins, from 10 to 200,000.
Press Spin again to rerun with fresh randomness.
Compare hot/cold numbers at 100 spins versus 100,000.
Worked example in Canadian dollars
Example. At 100 spins the "hottest" number often shows 7–8 hits against an expected 2.7. At 100,000 spins every pocket sits within about ±3% of 2,703 hits. The longest same-colour run in 10,000 spins is usually 12–16.
About the wheel simulator
The wheel simulator exists to kill a myth. Spin a fair wheel a few dozen times and some numbers will have hit three or four times while others never appear — the raw material of every "hot number" and "due number" theory. Spin it a hundred thousand times and every pocket converges on 2.70% (2.63% American).
The tool also tracks the longest run of one colour. Runs of eight or nine reds in a row appear routinely in a few thousand spins, which is exactly what breaks Martingale bettors in practice.
Put it into practice
Numbers are more useful with a real table in front of you. Practise on our free European wheel. When you are ready to play for real, our top pick for Canadians is Rainbet: code BOOST20 adds a permanent 20% rakeback boost that lowers the effective edge on every spin, which you can see in the rakeback calculator.
