Learn & Understand

📜 History

Roulette developed in 18th-century France. The earliest single-zero form appeared in Parisian casinos in the 19th century. The American variant with an additional double-zero came slightly later in the United States.

The European wheel with a single zero is today considered the more player-friendly standard form and is the most commonly offered variant online.

🌍 Where popular today

Roulette is an icon of the classic casino — from Monte Carlo to Las Vegas, from Baden-Baden to Macau.

All major online operators offer it, often as a live-dealer version with a real wheel and croupier streamed in real time.

🎯 Rules

You place chips on the table: individual numbers (straight up), colours (red/black), even/odd, dozens, columns or other fields.

When the ball lands, all bets whose condition is met win. Payouts: straight up 35:1, colour/even/high 1:1, dozen/column 2:1.

📊 Odds & maths

On European roulette the house edge is a constant 2.70% on every standard bet — that single zero is the source.

On the American double-zero wheel the edge rises to 5.26%. With otherwise identical payouts the European wheel is always preferable.

✨ Beginner's guide

Beginners often start with simple bets like red/black or even/odd — these pay 1:1 and win just under 50% of the time.

Whatever strategy you pick (Martingale, D'Alembert, etc.), mathematically the 2.70% house edge holds in the long run. On Play Palace Labz you practise the feel of the game without real risk.
