What Is European Roulette?
European roulette is a casino table game played on a wheel with 37 numbered pockets: 1 through 36 (alternating red and black) plus a single green zero. Players bet on where a small ivory ball will land after the wheel is spun. The game originated in 18th-century France and has become the standard form of roulette in European and UK casinos, as well as the most widely available version online.
The defining characteristic of European roulette - the feature that makes it meaningfully better for players than American roulette - is its single zero. American roulette has two zero pockets (0 and 00), nearly doubling the house's advantage from 2.70% to 5.26%. On this simulator, you play the European single-zero version at all times.
European Roulette Bet Types & Payouts
European roulette offers two categories of bets - inside bets (placed on specific numbers or groups of adjacent numbers on the main grid) and outside bets (placed on broader categories like colour or dozen). The table below shows every bet type available in this simulator, along with its payout ratio and the number of pockets it covers.
| Bet Type | Coverage | Payout |
|---|---|---|
| Straight Up | Single number | 35:1 |
| Split | 2 adjacent numbers | 17:1 |
| Street | 3 numbers in a row | 11:1 |
| Corner | 4 numbers sharing a corner | 8:1 |
| Six Line | 6 numbers, 2 adjacent streets | 5:1 |
| Dozen / Column | 12 numbers | 2:1 |
| Red / Black / Odd / Even / High / Low | 18 numbers | 1:1 |
Why Practice with a Free Simulator?
Even experienced roulette players benefit from simulator practice. Here are the four main reasons players use this tool:
- Learn the table layout. The physical arrangement of numbers on the betting felt is not intuitive. Clicking through the layout internalises where splits, corners, and streets sit before you sit down at a real table.
- Test betting systems risk-free. The Martingale, Fibonacci, D'Alembert, and Labouchère systems all behave differently in practice. Running hundreds of spins on a simulator reveals their real variance, win rates, and bankroll requirements without costing a penny.
- Understand the odds. Watching live statistics - hot numbers, colour distributions, expected vs actual returns - builds genuine intuition for probability. The 2.70% house edge is abstract; 1,000 spins of data makes it concrete.
- Practice announced bets. Neighbour bets and racetrack sections require memorisation of the wheel sequence. Repeated simulator use makes these automatic.
The Single-Zero Advantage: Why European Beats American
The most important decision a roulette player makes is choosing the right wheel. European roulette's single zero is not a minor detail - it fundamentally changes the game's mathematics:
Over 1,000 spins at £1 per spin, the expected loss is £27 on a European wheel versus £52.60 on an American wheel. The difference compounds significantly over a longer session. For a full comparison, see our European vs American roulette guide.
Key Fact
The house edge in European roulette applies equally to every single bet type. There is no bet with better or worse odds than 2.70%. The only exception is French roulette with La Partage or En Prison rules, which reduces the edge to 1.35% on even-money bets.
European Roulette Wheel Sequence
The 37 numbers on a European wheel are arranged in a specific clockwise sequence designed to balance high and low numbers, and alternate red and black pockets as evenly as possible. The full sequence is:
The red numbers are: 1, 3, 5, 7, 9, 12, 14, 16, 18, 19, 21, 23, 25, 27, 30, 32, 34, 36. All remaining numbers (excluding zero) are black. See our full wheel layout guide for a detailed breakdown of the sequence, racetrack sectors, and why the layout is designed this way.
