What Happens at the Table
You sit down at a roulette table, and before you can place a bet, your cash has to become chips. This is the first procedural step many new players get wrong. Roulette does not use the same chips as other table games. You buy in with cash or a casino cheque, and the dealer gives you a stack of wheel chips in a colour assigned only to you. These chips have no cash value printed on them; their value is whatever you paid per chip at the buy-in. If you hand over 100 units and ask for chips at 2 units each, you receive 50 chips worth 2 units apiece. That value is tracked by the dealer, not printed on the chip.
Because these wheel chips are unique to your seat, you cannot cash them at the main cage. When you finish playing, you must exchange them back at the roulette table for standard value chips, which you can then take to the cage. Walking away from the table with wheel chips in your pocket is a common mistake: they are worthless anywhere else in the building, and on a future visit the table may not honour them at all.
The table itself is a layout printed on felt. It shows a grid of the numbers 0 through 36, arranged in three columns of twelve, plus additional marked areas around the outside for broader bets such as red or black, odd or even, and ranges of numbers. The wheel sits at one end of the table and carries the same numbers in a different order, alternating red and black pockets around the rim, with the zero pockets in green. A small white ball is spun in the opposite direction to the wheel's rotation. The ball loses momentum, rattles across the deflectors, and settles into one of the numbered pockets. That pocket decides every bet on the table.
The Sequence of a Round
A round moves through a fixed rhythm, and knowing that rhythm is what lets you place bets without fumbling. The dealer opens betting by announcing it, usually with a phrase like "place your bets." You now have a window of time to put chips on the layout. You may place chips yourself, or you may hand them to the dealer and state where you want them, which is useful for bets you cannot reach from your seat.
When the ball is already moving, the dealer will call "no more bets" at a point before the ball drops. From that moment, nothing on the layout may be touched. Any chip placed after the call is void, and the dealer will return it. Reaching across the table to adjust a bet after the call is one of the fastest ways to annoy the table and draw a correction from the dealer. The ball settles, the dealer marks the winning number on the layout with a marker, and losing bets are cleared first. Winning bets are then paid, and only after all payouts are complete does the dealer remove the marker and open betting for the next round. You cannot touch your winnings until the marker is off the table.
Every bet on the layout is settled against the single winning number. There is no player hand, no decision to make after the spin, and no way to influence the ball. The only decisions you make are which bets to place and how much to stake on each. The round then resolves entirely on its own.
Reading the Two Wheel Layouts
Not all roulette wheels are built the same way, and the difference is the single most important thing to check before you sit down. A European wheel has 37 pockets: the numbers 1 through 36 plus a single zero. An American wheel has 38 pockets: the same numbers plus both a single zero and a double zero. The extra pocket is not cosmetic. It changes the arithmetic on every bet on the table, because the zero pockets are not covered by the outside bets such as red or black, odd or even, or high or low.
On a European wheel, a bet on red covers 18 of the 37 pockets. On an American wheel, the same bet covers 18 of 38. The payout is identical on both layouts, but the chance of winning is lower on the American wheel. That gap is the house edge, and it is larger on the American layout for every bet that does not specifically include the zeros. The rule of thumb is simple: if you have a choice of tables, the wheel with fewer zero pockets is the better place to put the same bet.
| Feature | European wheel | American wheel |
|---|---|---|
| Pockets | 37 | 38 |
| Zero pockets | 1 (single zero) | 2 (single and double zero) |
| Red or black coverage | 18 of 37 pockets | 18 of 38 pockets |
| House edge on outside bets | Lower | Higher |
| Layout marking | One zero on the felt | Zero and double zero on the felt |
The table layout always shows which wheel you are playing. If the felt has both a 0 and a 00 at the end of the number grid, it is an American layout. If it has only a single 0, it is European. Some venues also offer French roulette, which uses the European wheel but adds specific rules for certain even-money bets when the ball lands on zero, such as holding the bet for the next spin or returning half the stake. Those rules are printed on the table or available from the dealer, and they change the arithmetic on the bets they cover.
The Main Bets and How They Differ
Every roulette bet is a wager that the ball will land in a specific pocket or a group of pockets. The bets are usually divided into inside bets, placed on the number grid itself, and outside bets, placed on the marked areas around the grid. The distinction matters because the two groups carry different payout structures and different house edges.
Inside bets cover individual numbers or small groups of them. A straight-up bet is a chip placed entirely on one number. A split bet sits on the line between two numbers and covers both. A street bet covers a row of three numbers, a corner covers four, and a six-line covers two adjacent rows. These bets pay more because they cover fewer pockets, and they lose more often for the same reason.
Outside bets cover large groups. Red or black covers 18 pockets, odd or even covers 18, and high or low covers the numbers 1 through 18 or 19 through 36. Dozens and columns each cover 12 numbers. These bets pay less but hit more frequently. The catch is that on both wheel layouts, the zero pockets sit outside all of these groups, so a ball landing on zero loses every outside bet on the table unless a specific rule, such as the French even-money rules, says otherwise.
| Bet | Numbers covered | Payout | How it behaves |
|---|---|---|---|
| Straight-up | 1 | 35 to 1 | Rare wins, large payout |
| Split | 2 | 17 to 1 | Slightly more frequent than a straight-up |
| Street | 3 | 11 to 1 | Covers a full row on the grid |
| Corner | 4 | 8 to 1 | Covers a block of four numbers |
| Six-line | 6 | 5 to 1 | Covers two adjacent rows |
| Column or dozen | 12 | 2 to 1 | Outside bet, moderate frequency |
| Red, black, odd, even, high, low | 18 | 1 to 1 | Outside bet, highest hit frequency |
The payouts in the table are the standard ones printed on the layout, and they are the same on European and American wheels. What changes between the two layouts is not the payout but the chance of winning, because the extra zero pocket is not covered by any of these bets except a straight-up bet on zero itself. A straight-up bet on any number pays 35 to 1 on both wheels, but the chance of that number arriving is 1 in 37 on a European wheel and 1 in 38 on an American wheel. The payout does not adjust for that difference, which is precisely where the house edge lives.
What You Control and What You Do Not
Roulette is a game of independent spins. The wheel has no memory, and no sequence of past results changes the odds on the next spin. A number that has not appeared for an hour is not due, and a number that has appeared three times in a row is not less likely to appear again. Each spin starts from the same set of pockets, and the ball is equally capable of landing in any of them on any given spin, subject to the physical behaviour of the wheel and ball.
What you control is which bets you place, how much you stake, and how long you stay at the table. Bet selection changes the shape of your session: inside bets produce longer losing runs punctuated by larger wins, while outside bets produce more frequent wins that are smaller relative to the stake. Neither choice changes the built-in edge of the game. The house edge on roulette is fixed by the wheel layout and the payout schedule, and no betting pattern alters it. A progression system that raises or lowers stakes after wins or losses changes the distribution of outcomes across a session, but it does not change the expected loss per unit wagered.
If you want to know the exact edge on a specific bet at the table you are playing, the arithmetic is available from the wheel layout and the printed payouts. The house edge on a given bet is the difference between the true odds of the bet winning and the payout the table offers. On a European wheel, a straight-up bet wins 1 time in 37 but pays 35 to 1, which leaves a gap between the payout and the true odds. That gap, expressed as a percentage of the stake, is the house edge. The same calculation on an American wheel yields a larger gap because the denominator is 38 instead of 37. You do not need to memorise the percentages; you need to know that the wheel with fewer zero pockets leaves a smaller gap on every bet that does not include the zeros.
Procedural Mistakes That Cost You Nothing but Time
The most common mistakes at a roulette table are not about strategy. They are about procedure, and they are easy to avoid once you know the rhythm of the game. The first is placing a bet after the dealer has called no more bets. The call is not a suggestion, and a late chip will be returned to you. If you are unsure whether betting is open, wait for the dealer to remove the marker from the previous winning number. That is the signal that the next round has begun.
The second is touching your chips after the ball has dropped. Once the winning number is marked, the dealer clears losing bets and pays winners in a specific order. Reaching in to collect a winning bet before the marker is removed will draw a correction, and it can confuse the settlement of neighbouring bets. Keep your hands off the layout until the dealer has finished paying and lifted the marker.
The third is forgetting that your wheel chips are not cash. When you stand up from the table, ask the dealer to colour you up into standard value chips. If you carry wheel chips to another table or to the cage, they will be refused. The dealer will handle the exchange at the table where the chips were issued, and that exchange is the only way to convert them back into something you can cash.
FAQ
What is the difference between European and American roulette?
The difference is the number of zero pockets on the wheel. A European wheel has a single zero and 37 pockets in total, while an American wheel has a single zero and a double zero, making 38 pockets. The extra pocket on the American wheel increases the house edge on bets that do not cover the zeros, because the payout schedule stays the same while the chance of winning falls.
Can I bet on zero in roulette?
Yes. Zero is a number like any other, and you can place a straight-up bet on it, or include it in split, street, or corner bets that cover adjacent numbers. On an American wheel, the double zero is also a separate pocket you can bet on directly. The zeros are green, which is why they are not covered by the red or black outside bets.
What does a roulette strategy chart look like?
Roulette does not have a strategy chart in the way blackjack does, because there is no decision to make after the ball is released. The only decisions are which bets to place and how much to stake. Any published roulette system is a staking plan, not a strategy, and it changes the timing and size of wins and losses without changing the built-in house edge. The closest thing to a useful reference is a payout table, which is printed on the layout itself.
