Roulette Guide: Rules, Odds & House Edge

Roulette is not about gut feel — the dealer (or simulator) spins the wheel, the ball lands on a number, and payouts follow the odds table.

Before the spin, pick a betting area: Red/Black, Odd/Even, High/Low (outside bets at 1:1), Dozen/Column (2:1), or straight up on a single number (35:1). Win and you are paid per the table; lose and the stake goes to the house.

Online live and RNG tables can use European, American or French rules. Check the pocket count before you play — an extra 00 on American wheels nearly doubles the long-term loss rate.

Beginners should start with outside bets to learn the pace. Straight-up bets offer 35:1 payouts but only hit 2.7% of spins. Choose the wheel first, then choose the bet type.

Always prefer European (or French La Partage). The American 00 raises house edge from 2.7% to 5.26%.

*French La Partage returns half your even-money stake when zero hits; En Prison leaves the bet for the next spin under the same rule — either can cut effective edge to about 1.35%. Availability varies by provider and region, so check the displayed table rules.

If this is your first real or demo session, keep the decision simple: choose a European wheel, start with flat stakes, learn outside bets, and stop at your loss limit.

Walk through once with virtual chips in the free simulator — no real money is involved while you learn pick → spin → payout.

1. 01

   Pick a chip

   Select a chip value such as $10 at the bottom of the simulator (practice mode uses virtual chips — no real money).

2. 02

   Tap a betting area

   For your first spin, tap Red or Black on the outside layout (1:1). You will see the chip stack on that section.

3. 03

   Confirm your stake

   The sidebar shows total bet for the round. Clear and rebet, or use ½ / 2× to adjust chip size.

4. 04

   Spin the wheel

   Press Spin — the wheel turns for about three seconds, then the ball settles in a pocket.

5. 05

   Check the payout

   Red or Black wins pay 1:1. If zero hits, most outside bets lose. Your balance updates — spin again to practice.

Want to verify payouts bet by bet? Jump to the demo section and cross-check the sidebar odds table. For the math behind the edge, see our house edge guide.

Every standard bet on a European wheel carries a 2.7% house edge long term — the difference is variance, not which bet “must win.”

In other words, Red/Black and straight up lose at the same long-term rate — outside bets mean smaller stakes over many spins; straight up means bigger swings on fewer hits. For how the edge is calculated, see our house edge guide; for RTP and expected value, see the RTP explainer.

Every standard European bet keeps a 2.7% house edge — the methods below only change your bankroll curve and swing size, not expected value.

A staking system changes the next amount, not the wheel. Flat betting stays level, negative progressions increase after losses and positive progressions increase after wins.

Martingale, Fibonacci, Labouchère and the other familiar methods still face zero, independent spins, finite bankroll and a table maximum. Compare peak stake and total wager before judging a system by one recovered run.

• Flat betting avoids progression-driven stake growth but does not remove losses.
• Negative progressions can reach the table maximum during an ordinary losing run.
• Positive progressions risk recent winnings and leave expected value unchanged.

Zero, Voisins du Zéro, Tiers du Cylindre, and Orphelins — preset call-bet bundles that still carry a 2.7% house edge long term.

French call bets are shortcuts for several inside placements. Jeu Zéro uses 4 units, Voisins du Zéro 9, Tiers du Cylindre 6 and Orphelins 5; every component chip settles separately.

Use the dedicated bet-types guide to see each straight, split, street and corner placement. A call-bet name never creates one special payout or a lower house edge.

If a system truly beat the house, why would anyone sell it to you?

• Prefer European tables

  Confirm 37 pockets with a single zero before you bet. If you see 00, switch tables or platforms.

• Set a loss limit

  Roulette is entertainment, not investing — stop when you hit your budget, never chase losses.

• Check table limits

  Make sure the minimum fits your planned unit and the maximum cannot pressure you into chasing a progression.

• Understand zero

  Zero makes most outside bets lose — read the odds table so you know where the 2.7% edge comes from.
