How the calculation works
A simulator for European roulette (37 pockets, 0โ36). Bet virtual chips on single numbers, colours, odd or even, low or high, dozens and columns. Payouts (winnings per unit staked; the stake is returned as well) Single number (straight up): 35 to 1 Red/black, odd/even, 1โ18/19โ36: 1 to 1 Dozens (1โ12, 13โ24, 25โ36) and columns: 2 to 1 When 0 comes up, every bet loses except a straight-up bet on 0. Results are drawn from the 37 pockets with equal probability using the browserโs cryptographic random number generator.
Worked example
Betting 100 on red Win 18/37 (about 48.6%) โ +100 Lose 19/37 (about 51.4%) โ โ100 Expected value: 100 ร (18 โ 19) รท 37 โ โ2.7 Whatever you bet on, the house edge is 1/37 โ 2.70%.
Things to be aware of
- American roulette has both 0 and 00 (38 pockets), which raises the house edge to about 5.26%.
- Betting systems such as the Martingale (doubling after each loss) do not change the negative expected value in the long run.
- Only virtual chips are used; no money changes hands.
