European Roulette: A Complete Beginner's Guide

A Brief History of Roulette

Roulette was born in 18th-century France. The mathematician and physicist Blaise Pascal is often credited with an early version of the wheel - not as a game, but as a by-product of his attempts to create a perpetual motion machine in the 1650s. The wheel's near-perfect balance and smooth rotation made it ideal for gambling.

By the 1790s, a recognisable roulette game was being played in Paris. Early French wheels featured both a zero and a double-zero. In the 1840s, casino operators François and Louis Blanc introduced the single-zero wheel in Bad Homburg, Germany, as a competitive advantage to attract players. The single-zero version became known as "European roulette" and spread across Europe, becoming the global standard outside the United States - where the double-zero American wheel persisted.

The Wheel and Table at a Glance

European roulette has two physical components:

The Wheel

Key Wheel Facts

• 37 pockets numbered 0–36
• Numbers 1–36 are coloured alternately red and black
• Zero (0) is green - the house's advantage pocket
• Numbers are not in numerical order around the wheel - they follow a carefully balanced sequence
• The wheel spins clockwise; the ball is released counter-clockwise

The Betting Table

Table Zones at a Glance

• Inside betting area: The main 3×12 number grid plus zero - for specific number bets
• Outside betting area: Surrounding boxes for broader category bets
• Dozens strip: 1st 12 / 2nd 12 / 3rd 12 - three groups of twelve numbers
• Even-money boxes: Red, Black, Odd, Even, 1–18, 19–36

Your First Bet: Red or Black

The easiest bet in European roulette is Red or Black. Place a chip on the red or black diamond in the outside betting area. If the ball lands on your chosen colour, you win - your stake is doubled. If it lands on the other colour or on zero, you lose.

• Win probability: 18/37 = 48.65%
• Payout: 1:1 (double your money)
• House edge: 2.70%

This bet wins almost - but not quite - half the time. The 1.35% gap (zero means you win less than 50% of spins) is the house's edge. Odd/Even and 1–18/19–36 work identically.

Five Bets Every Beginner Should Know

Reading the Table Layout

The betting table is divided into clear zones. Learning to read it takes only a few minutes:

1. Zero cell (far left): A single cell spanning all three rows. Betting here is a straight-up bet on zero at 35:1.
2. Number grid: 12 columns of 3 numbers each. Top row = 3,6,9…36; Middle = 2,5,8…35; Bottom = 1,4,7…34. Numbers increase left to right.
3. Column labels (right edge): "2 to 1" boxes. Clicking here bets on all 12 numbers in that column.
4. Dozen strip (below grid): 1st 12 (1–12), 2nd 12 (13–24), 3rd 12 (25–36). Each pays 2:1.
5. Outside boxes (bottom): 1–18, Even, Red, Black, Odd, 19–36. All pay 1:1.
6. Intersections: The lines and corners between numbers are also valid bet positions - splits, streets, corners, and six-lines.

Common Beginner Mistakes to Avoid

• Playing American roulette by mistake. Always check for a single zero. American roulette's double zero nearly doubles the house edge. See our EU vs American guide.
• Believing in "hot numbers". The wheel has no memory. A number that hasn't appeared for 20 spins is not "due" - its probability remains 1/37. This is the Gambler's Fallacy. See our statistics guide.
• Chasing losses. Increasing bets to recover losses is the most common way players lose large sums quickly. Set a loss limit before you start and respect it.
• Using a system without understanding its variance. The Martingale seems safe - until a 7-loss streak hits. Run systems in our free simulator before risking real money.
• Not knowing the bet before placing it. Clicking at random on the table produces bets you didn't intend. Learn where each bet type is placed before your first real-money session.
• Ignoring table limits. Minimum and maximum bet amounts apply per position. A table with a £1 minimum and £100 maximum will collapse any Martingale system after 7 doublings from a £1 base.
