What is Roulette?
Roulette — from the French word meaning "little wheel" — is one of the oldest and most iconic casino games in existence. Its origins date back to 18th-century France, and the game has remained fundamentally unchanged for over 300 years. Today it is one of the most popular games at both land-based and online casinos worldwide.
The game consists of a spinning wheel with numbered pockets (0–36 in European roulette; 0 and 00 in American roulette) and a small white ball. Players bet on where they think the ball will land after the wheel is spun. Bets can be placed on a single number, a group of numbers, the colour (red or black), whether the number is odd or even, or high (19–36) versus low (1–18).
Roulette is almost entirely a game of chance — no skill or strategy can change the underlying mathematical odds. However, understanding the different variants and betting structures allows you to make smarter decisions and choose the version of the game that gives you the best odds.
Roulette Variants: European, American & French
European Roulette
The standard version found at most UK online casinos. The single zero halves the house edge compared to American roulette. Always choose this over American if both are available.
French Roulette
Identical to European roulette but includes the La Partage rule — when the ball lands on zero, half of all even-money bets are returned. This cuts the house edge on even-money bets to just 1.35%.
American Roulette
The double zero pocket nearly doubles the house edge compared to European roulette. There is no strategic advantage to playing American over European roulette — avoid it unless it's the only option available.
The Roulette Wheel Layout
European wheel numbers are not sequential — they are arranged specifically to alternate high/low, red/black, and odd/even as evenly as possible.

Popular Roulette Betting Systems
Negative Progression The Martingale
The most well-known betting system. After every loss, you double your bet. After a win, you return to your starting bet. The logic: a win will always recover all previous losses plus one unit of profit.
Example (£1 start):
Lose £1 → Bet £2 → Lose £2 → Bet £4 → Win £4 = +£1 profit
❌ The Risk:
A losing streak of 10 requires a £1,024 bet to recover £1. Table limits and your bankroll will stop you far before this becomes safe.
Negative Progression The Fibonacci System
Bets follow the Fibonacci sequence: 1, 1, 2, 3, 5, 8, 13, 21... After a loss, move one step forward. After a win, move two steps back. More conservative than Martingale but still carries escalation risk.
Sequence: 1→1→2→3→5→8→13→21→34→55...
After 9 consecutive losses, your next bet is £55 to recover a £1 starting unit.
Positive Progression The Paroli System
The opposite of Martingale — double your bet after each win, return to the base bet after a loss or after 3 consecutive wins. The idea: ride winning streaks while keeping losses small. Considered safer for recreational players as you only risk winnings.
Win with £1 → Bet £2 → Win → Bet £4 → Win → Return to £1 (3-win profit: £7)
Losses are always limited to one base unit per sequence.
Flat Betting D'Alembert System
Increase your bet by one unit after a loss; decrease by one unit after a win. Slower progression than Martingale, less risk of hitting table limits. The system assumes that wins and losses will eventually balance out — which statistically holds, but on a timeline measured in thousands of spins.
Live Dealer Roulette
Live dealer roulette streams from professional studios in real time, with real wheels, real balls, and real human dealers. The most popular provider is Evolution Gaming, whose live roulette games are available at virtually every major UK-licensed online casino.
🎥 Immersive Roulette
Multiple camera angles including extreme slow-motion close-ups of the ball dropping into the pocket. The most cinematic live roulette experience available online.
⚡ Lightning Roulette
A twist on European roulette where random "Lightning Numbers" receive multiplied payouts of 50x to 500x per round. The house edge is slightly higher (3.0%) but the jackpot potential adds excitement.
🎯 Speed Roulette
Rounds last just 25 seconds. The ball is spun before betting time ends, allowing results to appear twice as fast as standard live roulette. Suited to players who want faster action.
💻 Auto Roulette
An automated live wheel with no dealer. Spins every 20–30 seconds around the clock. Lower bet limits than standard live roulette — ideal for casual players.
