Roulette rules: zeros, payouts and the total bet
Understand single-zero and double-zero wheels, standard payouts and how several chips combine into one round's cost.
On this page
Check the wheel and paytable before placing roulette chips. A single-zero wheel, a double-zero wheel and a game with special multipliers can use different rules even when the betting layout looks familiar.
Then add up every chip on the layout. The total stake for the round can be much larger than the denomination shown on the selected chip.
Count the pockets
A standard single-zero wheel has numbers 1 through 36 plus 0, making 37 pockets. A standard double-zero wheel adds 00, making 38. Both zero pockets sit outside the ordinary red/black, odd/even and low/high groups.
On an ordinary red bet, there are 18 winning pockets; black and zero outcomes lose the stake under standard rules without a zero concession. Assuming equally likely pockets and a standard 1:1 profit payout, the expected loss is 1/37 of the stake on a single-zero wheel, about 2.70%, or 2/38 on a double-zero wheel, about 5.26%.
Those are long-run mathematical expectations under those rules. They do not predict the next spin, guarantee a session result or describe a variant with different zero rules.
Read profit payouts separately from returned stake
| Bet | Profit if it wins | Total returned including that bet's stake |
|---|---|---|
| One number at 35:1 | 35 units | 36 units |
| Two-number split at 17:1 | 17 units | 18 units |
| A dozen at 2:1 | 2 units | 3 units |
| Red or black at 1:1 | 1 unit | 2 units |
These are examples of standard payouts, not a substitute for the current game's paytable. Multiplier variants can reduce ordinary payouts or add separate conditions. French-style rules may treat certain zero outcomes differently. Verify the actual rule rather than inferring it from the wheel's appearance.
Add all chips before confirming
If you place 1 SC on red and 1 SC on each of three individual numbers, the round costs 4 SC. A winning chip does not erase the cost of the other bets.
For example, if red wins and none of those three numbers wins, the red bet returns 2 SC including its stake. Against 4 SC placed, the round's net result is minus 2 SC. A winning animation can therefore accompany an overall loss on the layout.
Check what Repeat, Double or Rebet will do before using it. These controls may act on the entire previous layout. Clear unwanted chips and confirm the total before the betting window closes.
Past results do not make a color due
On an independent fair spin, a run of black outcomes does not increase the next spin's probability of red. A history display describes previous results; it does not remove the zero pockets or change the payout.
Increasing stakes after losses also does not remove the mathematical disadvantage. It raises the amount exposed and can run into your balance, personal limit or the table maximum.
Use the RTP guide to put long-run figures in context. If a round is disputed, save the round ID, wheel version, complete chip layout and settlement, so support can compare the full stake with the return.
