What's the difference between European and American roulette?

European roulette has one zero pocket; American roulette has two (0 and 00), which roughly doubles the house edge — European is generally the better choice when available.

What roulette bet has the best odds?

Outside bets like red/black or odd/even pay close to even money and hit close to half the time, making them the lowest-variance option.

Can I predict where the ball will land?

No — certified roulette wheels (physical or RNG-based) are independently audited, and each spin is statistically independent of the last.

What is the house edge on roulette?

European roulette carries roughly a 2.7% house edge; American roulette is roughly double that due to the extra zero pocket.

What Is Online Roulette?

Roulette is a wheel-and-ball game where a ball is spun around a numbered wheel (0-36 in European roulette) and lands on a single number and color; you bet on where it will land before the spin, choosing anything from a single number to broader groups like red/black or odd/even.

It's one of the simplest casino games to learn since every bet type pays a fixed, known odds — there's no hand-reading or bonus-feature complexity, just picking where you think the ball lands. This guide covers the main bet types and how their odds compare.

How to Play Online Roulette

Follow these steps for a typical round.

Choose a table

European roulette (single zero) generally offers better odds for players than American roulette (double zero) — pick European where available.

Place your bets before the spin

Bet on a single number, a group of numbers, or a broader category like red/black during the betting window.

Watch the spin

The wheel spins and the ball is released — where it lands decides every bet on the table for that round.

Collect winnings automatically

Winning bets pay out immediately based on their fixed odds; losing bets are cleared for the next round.

Roulette Tips From Our Reviewers

Habits that make roulette sessions more sustainable.

Prefer European over American roulette

The single-zero wheel gives the house a smaller edge than the double-zero version, which works in your favor over time.

Mix outside and inside bets

Outside bets (red/black, odd/even) pay less but hit more often; inside bets (single numbers) pay more but hit rarely — balance the two to your risk comfort.

Set a per-spin budget, not just a session one

Since every spin is independent, deciding your bet size per spin in advance keeps a losing streak from escalating.

Ignore betting systems that promise guaranteed wins

No betting pattern changes the underlying odds of an independent spin — treat systems as a staking style, not a guarantee.

Roulette Terms to Know

Outside Bet: A bet on a broad category like red/black, odd/even, or a dozen, paying lower odds for a higher chance of hitting.
