Roulette is simple: the ball lands in one numbered pocket, and every bet covering that pocket wins. What makes it interesting is the range of bets, from a single number to almost half the wheel. Knowing how often each one wins, and what it pays, makes the trade-offs clear.
Inside and outside bets
Inside bets are placed on the numbered grid: a single number (straight up), two neighbouring numbers (split), a row of three (street), a block of four (corner) or two rows of six (six line). Outside bets sit around the grid and cover larger groups: a dozen, a column, red or black, odd or even, and low (1 to 18) or high (19 to 36). Zero isn't part of any outside bet.
Payouts and chances on a European wheel
| Bet | Numbers covered | Pays | Chance of winning |
|---|---|---|---|
| Straight up | 1 | 35 to 1 | 2.70% |
| Split | 2 | 17 to 1 | 5.41% |
| Street | 3 | 11 to 1 | 8.11% |
| Corner | 4 | 8 to 1 | 10.81% |
| Six line | 6 | 5 to 1 | 16.22% |
| Dozen or column | 12 | 2 to 1 | 32.43% |
| Red/black, odd/even, low/high | 18 | 1 to 1 | 48.65% |
European roulette has 37 pockets: 1 to 36 plus a single zero.
The zero is where the house edge comes from. Payouts are set as if the wheel had 36 numbers, but it has 37 pockets. A straight-up bet wins 1 time in 37 but is paid as if it won 1 time in 36. That gap works out to 1/37, or 2.70%, and it's the same on every bet on the table. Choosing outside bets changes how often you win, not what roulette costs.
European, American and French wheels
- European roulette (single zero, 37 pockets): 2.70% house edge on every bet.
- American roulette adds a double zero (38 pockets). The edge rises to 5.26% on most bets, and the five-number bet on 0, 00, 1, 2 and 3 carries 7.89%.
- French roulette uses a single-zero wheel, often with the La Partage rule: when the ball lands on zero, even-money bets lose only half. That cuts the edge on those bets to 1.35%. A similar rule, En Prison, holds the bet for one more spin instead.
Where you have a choice, a single-zero wheel always costs less, and even-money bets under La Partage are the cheapest bets in roulette.
Multiplier versions
Some live roulette games add random multipliers to a few numbers each round. To pay for them, the standard straight-up payout is reduced, for example to 29 to 1. The overall return can end up close to standard European roulette, but the swings are bigger. The game's help screen lists its exact payouts and RTP.
Why betting systems don't work
The Martingale is the best-known system: bet on red, and double your stake after every loss, so one win recovers everything plus your first stake. Starting at RM5, each successful sequence wins just RM5. But seven losses in a row means you've lost RM635 and your next bet must be RM640.
| Losses in a row | Total lost | Next bet needed |
|---|---|---|
| 3 | RM35 | RM40 |
| 5 | RM155 | RM160 |
| 7 | RM635 | RM640 |
| 8 | RM1,275 | RM1,280 |
On a European wheel, red loses 19 times in 37 (zero counts as a loss). Seven losses in a row happen about once in every 106 sequences, which is rare in one sitting but likely over many sessions. When it comes, it wipes out more than a hundred small wins, or the table maximum stops you doubling at all. Fibonacci, D'Alembert and other systems rearrange your stakes in different ways; none changes the 2.70% charged on every bet.
The same goes for hot and cold numbers. The results board shows what has happened, but the wheel has no memory, and every spin is independent.
Making a budget last
- Your average cost is 2.70% of everything you wager on a single-zero wheel: RM2.70 per RM100 staked.
- Even-money bets keep your balance steadier; straight-up bets swing it harder. The average cost is the same.
- Live roulette can spin every minute or so, so a fixed stake and a time limit matter more than which bet you choose.
- Never raise your stake to recover losses. That's how systems fail.
