For adults of legal gambling age only. Roulette is a game of chance, not a source of reliable income. No betting system guarantees a profit. You can lose your entire gambling budget.
1. How to Play
Roulette uses a numbered wheel and a betting layout. You choose a number or group of numbers before betting closes. The ball’s final pocket determines which bets win. Standard European roulette has 37 pockets: 1–36 and 0. Standard American roulette has 38: 1–36, 0 and 00. Zero pockets are neither red nor black and do not belong to odd/even, low/high, dozens or columns.
A round, step by step
- Read the table rules. Check the number of zero pockets, payout schedule, minimum and maximum stakes, and any special rules. Branded multiplier games may not use standard payouts.
- Choose a chip value and place a bet. Inside bets cover numbers on the grid. Outside bets cover larger groups, such as red or black. At a physical table, ask the dealer about chip values and how to place a selection.
- Finish before bets close. After “no more bets,” do not add, move or remove chips. Online, check the accepted-bet confirmation rather than assuming a click registered.
- Wait for settlement. Losing bets are collected and winning bets paid. At a physical table, wait until the dealer finishes settling the round before placing the next bet.
Common standard bets and payouts
The figures below assume a fair single-zero wheel with 37 equally likely pockets and standard payouts. “To 1” means net winnings; the winning stake is also returned.
| Bet and coverage | Winning numbers | Net profit payout | Chance per spin |
|---|---|---|---|
| Straight-up (one number) | 1 | 35:1 | 1/37 (2.70%) |
| Split (two adjoining numbers) | 2 | 17:1 | 2/37 (5.41%) |
| Street (one row) | 3 | 11:1 | 3/37 (8.11%) |
| Corner (four-number intersection) | 4 | 8:1 | 4/37 (10.81%) |
| Six line (two adjacent rows) | 6 | 5:1 | 6/37 (16.22%) |
| Dozen or column | 12 | 2:1 | 12/37 (32.43%) |
| Red/black, odd/even or low/high (1–18/19–36) | 18 | 1:1 | 18/37 (48.65%) |
For example, a winning 1-unit straight-up bet earns 35 units of profit and returns the 1-unit stake, for 36 units total. An ordinary red bet loses when zero lands. On a double-zero wheel, replace 37 with 38 in these probabilities; the usual payouts remain the same.
Why the house has an edge
On a standard single-zero straight-up bet, the expected net result per unit is (1 × 35 − 36 × 1) ÷ 37 = −1/37, or about −2.70%. The standard bets listed above share this house edge. On a standard double-zero wheel it is 2/38, about 5.26%. The American five-number bet on 0, 00, 1, 2 and 3 paying 6 to 1 is an exception with a higher edge, about 7.89%.
Independent source for the calculations: The Wizard of Odds roulette payout and house-edge tables explain the standard single-zero 2.70% edge, double-zero 5.26% edge and the American five-number bet’s 7.89% exception. These are theoretical figures under the stated rules and payouts, not a forecast of an individual session. Different wheels, special rules and altered paytables need separate calculations.
House edge describes a long-run average loss as a percentage of all money wagered, including money bet again. It is not a fee charged once to your deposit, a prediction for one session, or a limit on losses.
2. Strategies
The useful distinction is between managing exposure and changing the odds. Stake choices can change the size and timing of wins and losses, but they cannot turn a negative-expectation roulette game into a guaranteed winning one.
Compare rules, not lucky numbers
With otherwise identical standard payouts, a single-zero wheel has a lower house edge than a double-zero wheel. Some single-zero tables offer La Partage: half of an eligible even-money stake is returned on zero. Under that specific rule, the edge on those bets is about 1.35%, not zero. En Prison has different settlement procedures; read the exact rules rather than assuming the same treatment.
Read the rule-specific examples: Our La Partage half-stake explanation shows how a zero changes settlement on eligible even-money wagers; our En Prison stake-tracking example explains why an unresolved stake must not be counted as a new bet. Both are educational worked examples drawn from specific published rules, not promises about every roulette table or ways to predict results.
Flat betting and progressive systems
- Flat betting: keeping the same stake makes spending easier to track, but does not remove the house edge.
- Martingale: doubling after each loss grows exposure quickly. Starting at 1 unit, six consecutive losses cost 63 units and the next proposed bet is 64. A budget or table limit can prevent continuation. Recovery is never guaranteed.
- Fibonacci, D’Alembert and other progressions: changing the sequence does not change the wheel’s probabilities. A progression can produce frequent small wins and occasional large losses.
- Spreading bets: covering more numbers changes hit frequency and usually increases the total stake. A “winning” spin can still be a net loss when the return is less than everything staked that round.
Do not mistake history for a forecast
On a fair wheel with independent spins, previous results do not make a number or colour “due.” After a long red streak, the next spin’s chance of black is still 18/37 on a single-zero wheel. Results boards and streamer highlights show what happened, not what will happen.
A lower house edge does not make a session safe. For illustration, 100 units of total standard single-zero wagers have an expected loss of about 2.70 units, but the actual outcome can differ greatly. More spins and larger stakes increase the amount exposed to the house edge.
3. Tips
- Learn without staking money. Read the help screen or use a free demonstration to understand placement and settlement. Demo wins do not predict real-money results.
- Set an affordable loss limit and a time limit before starting. Treat the budget as entertainment money you could lose in full. Keep rent, bills and savings separate; never borrow to gamble.
- Check the full stake. Chip value, repeat-bet buttons, neighbours selections and multiple bets can make the total larger than expected. Table limits may apply separately to inside and outside bets.
- Read special-game rules. Multipliers, side bets, extra zero pockets or altered payouts need their own probability analysis. Do not apply the standard figures here automatically.
- Verify licensing and local legality. Use the relevant regulator’s official register rather than relying on a badge or an influencer’s recommendation. Check withdrawal conditions and promotional restrictions before depositing.
- Take breaks and do not chase losses. Avoid playing while impaired, distressed or tired. Stop at your planned limit instead of increasing stakes to recover money.
- Keep evidence of a disputed round. Record the game name, round ID, accepted stake and settlement, then use the operator’s dispute process. A frozen video alone does not establish the result.
- Act early if control becomes difficult. Use account limits, time-outs or self-exclusion, and seek support from a qualified local gambling-help service. Choosing not to play is always an option.
