You are buying into a wheel that never changes
Before you place a chip, understand that the wheel itself is fixed. A European wheel has 37 pockets numbered 0-36 with a single zero. An American wheel has 38 pockets with a single zero and a double zero. The sequence of numbers around the wheel is standardised for each type, and the ball always spins against the wheel's direction. Nothing about the wheel's construction changes between spins, between players, or between sessions. What changes is only where you put your money and how long you stay.
The game's object is simple: predict which pocket the ball will land in. You do not need to pick the exact number. Roulette lets you bet on groups of numbers, colours, odd or even, and ranges. Each bet type pays according to its probability, and each carries a house edge that is built into the payout structure rather than the wheel's behaviour.
From buying in to the first spin
You sit at the table and place cash on the felt. The dealer counts it and gives you roulette chips. These chips are distinct from chips used at other tables: they have no denomination printed on them, and their value is set when you buy in. The dealer places a marker on the rim showing what each of your chips is worth. When you leave, you must exchange these chips at the roulette table because the cashier cannot redeem them.
Once you have chips, wait for the dealer to close betting on the previous spin. The dealer clears losing bets, pays winners, and then opens betting for the next round. You place chips on the layout. You may place multiple bets on the same spin. When the ball is in motion, the dealer will announce that no more bets may be placed. From that point, nothing on the layout may be touched until the ball settles and the dealer marks the winning number.
The ball lands in a pocket. The dealer places a marker on the winning number on the layout, clears all losing bets, and pays winning bets according to the posted payout. Your chips remain on the table for the next spin unless you collect them. The round is complete when the layout is cleared and the dealer opens betting again.
What each decision point means
Roulette has fewer decision points than most table games. You decide what to bet, how much to stake on each bet, and when to stop. There is no skill element in the spin itself: the ball's final pocket is determined by physics and chance, not by any choice you make after the ball is released. The decisions that matter are all about bet selection and money management.
Your first decision is which wheel you are playing. The European layout has 37 pockets; the American layout has 38. The extra pocket on the American wheel does not pay more for any bet. It simply adds a losing number to every wager. For the same bet, the house edge is higher on the American layout. If a venue offers both, the wheel type is the single most important piece of information on the table.
Your second decision is which bets to place. Each bet type covers a different set of numbers and pays at different odds. The payout for a winning bet is always slightly less than the true odds of that bet winning, and that difference is the house edge. You cannot remove the edge by combining bets or by changing stakes. You can only choose which edge you are paying on each wager.
Main bet types and how their edges differ
The bets below are the standard inside and outside bets on a European wheel. The payouts are fixed by the game's rules; the house edge for each bet on a European wheel is the same for all bets shown, because the payout is set at the same proportional shortfall from true odds. On an American wheel, every bet carries a higher edge because of the double zero.
| Bet type | Numbers covered | Payout | What it means |
|---|---|---|---|
| Straight up | 1 number | 35 to 1 | A chip placed directly on one number |
| Split | 2 adjacent numbers | 17 to 1 | A chip placed on the line between two numbers |
| Street | 3 numbers in a row | 11 to 1 | A chip placed at the end of a row |
| Corner | 4 numbers in a square | 8 to 1 | A chip placed where four numbers meet |
| Six line | 6 numbers in two rows | 5 to 1 | A chip placed at the intersection of two rows |
| Red or black | 18 numbers | 1 to 1 | A chip placed on the colour section |
| Odd or even | 18 numbers | 1 to 1 | A chip placed on the odd or even section |
| Low or high | 18 numbers | 1 to 1 | 1-18 or 19-36 |
| Dozens | 12 numbers | 2 to 1 | First, second or third dozen |
| Columns | 12 numbers | 2 to 1 | A chip placed at the foot of a column |
The zero is not covered by any even-money bet, any dozen, or any column. When the ball lands on zero, all those bets lose unless you have placed a separate bet on the zero itself. Some European tables apply a rule that returns half of an even-money bet when zero appears, which reduces the house edge on those specific bets. Whether that rule is in force is printed on the table or stated in the venue's rules, and it changes the edge only for the even-money bets, not for the rest of the layout.
Inside bets, outside bets, and the announced bets
Inside bets are those placed on the numbered grid itself: straight up, split, street, corner, and six line. They pay more because they cover fewer numbers, and they win less often. Outside bets are those placed around the grid: colours, odd or even, low or high, dozens, and columns. They pay less but cover more numbers, so they win more often. Neither category changes the house edge on a given wheel; the difference is entirely in how the variance plays out over a session.
Some layouts also offer announced bets, sometimes called call bets or French bets. These are groups of numbers placed according to their position on the wheel rather than on the layout. Examples include bets covering a section of the wheel or a series of neighbours around a chosen number. These bets are placed by announcing them to the dealer, who positions the chips. The payout and the number of chips required depend on the specific bet and the wheel type, and the details are printed on the table's posted rules.
Procedural mistakes that cost new players
The first mistake is touching chips after the dealer has called no more bets. Once the ball is in motion and the call is made, the layout is frozen. Reaching in to adjust a bet will, at best, get the bet returned and a warning; at worst, it can be treated as an attempt to influence the outcome. Keep your hands off the felt from the moment the dealer closes betting until the winning number is marked.
The second mistake is leaving the table with roulette chips. Roulette chips have no value at the cashier. You must exchange them for regular casino chips at the roulette table before you leave. If you walk away with them, you are carrying chips that cannot be redeemed anywhere else.
The third mistake is betting on a system that claims to overcome the wheel. No progression of stakes, no pattern of red and black, and no sequence of numbers changes the house edge on any spin. Each spin is independent of the last. The wheel has no memory. A run of reds does not make black more likely, and a number that has not appeared for an hour is not due. Betting systems change the distribution of wins and losses across a session, but they do not change the expected loss per unit wagered.
What the posted rules tell you that this article cannot
This article explains the structure of roulette: the wheel, the round, the bets, and the edge. What it cannot tell you is the specific rule set at the table where you sit. The minimum and maximum stakes, the wheel type, whether the zero rule is in force, the availability of announced bets, and the exact payout schedule are all printed on the table or in the venue's posted rules. Read them before you buy in. A table with a lower minimum may carry a worse rule set, and a table with a higher minimum may be the only one offering the European wheel. The rules, not the felt colour or the dealer, determine what you are paying to play.
FAQ
Can I bet on every number and still lose at the expected rate?
You can place a chip on every number, but the total amount wagered will exceed the payout on the winning number. The house edge is built into the payout structure, so covering the entire layout guarantees that you lose money on the spin, not that you win it.
Do I need to know the wheel sequence to play?
No. The number sequence around the wheel matters only for announced bets that cover wheel sections. For standard inside and outside bets, you only need to read the layout. The wheel sequence does not help you predict where the ball will land.
What happens if the ball lands on zero when I bet on red?
Zero is not red or black, odd or even, low or high. A bet on red loses when zero appears unless the table applies a rule that returns part of even-money bets on zero. Whether that rule is in force is stated in the table's posted rules.
