The First Thing You Notice Is the Wheel
Walk up to a roulette table and your eye goes to the wheel first, because it is the only piece of equipment that moves. It sits at one end of the table, usually to the dealer's left from the players' side, and it is a heavy, shallow bowl with a sloped track around the rim. The dealer spins the wheel in one direction and launches a small ball along the track in the opposite direction. The ball loses speed, drops onto the spinning wheelhead, bounces across a set of metal deflectors, and settles into one of the numbered pockets.
The pockets alternate red and black, and the numbers are not arranged in numerical order around the wheel. A European wheel carries 37 pockets, numbered 0 through 36, with a single green zero. An American wheel carries 38 pockets, numbered the same way but with an additional green double zero. That second green pocket is not a cosmetic difference; it changes the arithmetic on every bet placed at the table.
Above the wheel you will usually see a display board showing the last several winning numbers, often in the order they hit. It is a record of past spins and nothing more. The wheel has no memory, and no number is due because it has not appeared recently.
The Felt Is a Map of Every Bet You Can Make
The table itself is a long, felt-covered surface with the betting layout printed on it. At the end opposite the wheel is a grid of numbers arranged in three columns of twelve, running 1 through 36, with the zero (and double zero on an American table) sitting at the top of the grid. This grid is where inside bets are placed. Around and below the grid are a series of labelled boxes for outside bets: red, black, odd, even, low numbers, high numbers, and the three dozen and column boxes.
Each player has their own coloured chips at a roulette table, which is different from most other table games. You buy in at the table, and the dealer gives you chips in a colour assigned only to you for that session. This is how the dealer knows whose bet is whose when chips sit crowded together on the same number. These roulette chips have no cash value printed on them; their value is whatever you paid for them at buy-in and is tracked by the dealer.
At the head of the table, near the wheel, the dealer works from a stack of the same coloured chips and a bank of cash-value chips used to pay winning bets. The layout is large enough that players on both sides of the table can reach the grid, and the dealer uses a long paddle to push chips across the felt for players who cannot reach.
What a Round Looks Like From Start to Finish
A round of roulette moves through a fixed sequence, and knowing it removes most of the intimidation of sitting down for the first time.
First, you buy in. Place your cash on the felt, not in the dealer's hand, and the dealer will exchange it for your coloured chips. You can buy in between spins, and the dealer will announce the value of your colour to the table so payouts are handled correctly.
Second, the betting window opens. The dealer clears the previous round's losing bets and pays winners, then announces that bets are open. You place chips on the layout wherever you want to bet. You can place multiple bets on a single spin, and you can keep placing them until the dealer calls for no more bets.
Third, the dealer spins the wheel and launches the ball. At some point during the spin, usually as the ball begins to slow, the dealer waves a hand over the layout and says that no more bets may be placed. From that moment, the layout is frozen.
Fourth, the ball lands in a pocket. The dealer places a marker, often called a dolly, on the winning number on the layout. The dealer then clears all losing bets first, and only after that pays winning bets. This order matters: the dealer sweeps losing chips off the felt before any winning chips are paid, so do not reach for your chips until the payout is complete.
Fifth, the round ends and the next one begins. Your chips remain on the felt only if you placed them there for that round; nothing carries over automatically. You can change your bets every spin, and you can leave the table at any time by asking the dealer to colour you up, which means exchanging your coloured roulette chips back into standard cash-value chips or cash.
Inside Bets and Outside Bets Are Different Animals
The roulette layout divides every possible bet into two families, and they behave differently in ways that matter to your bankroll.
Inside bets are placed on the numbered grid or on the lines between numbers. They pay more because they cover fewer outcomes. A straight-up bet on a single number pays 35 to 1, but the chance of hitting it on a European wheel is 1 in 37. The gap between those two numbers is the house edge at work. Split bets cover two numbers, street bets cover three, corner bets cover four, and six-line bets cover six. Each pays a smaller multiple as it covers more numbers.
Outside bets sit in the boxes around the grid and cover larger groups of numbers. Red or black, odd or even, and low or high each cover 18 numbers and pay even money. Dozens and columns each cover 12 numbers and pay 2 to 1. Because they cover more outcomes, they hit more often but pay less.
The comparison that matters most is how the two wheel types change the outside bets. On a European wheel, an even-money bet covers 18 of 37 pockets. On an American wheel, the same bet covers 18 of 38 pockets, because the extra double zero sits outside every outside-bet category. The bet pays the same, but it wins less often.
| Bet type | Numbers covered | Payout | Where it sits on the layout |
|---|---|---|---|
| Straight-up | 1 | 35 to 1 | On a single number |
| Split | 2 | 17 to 1 | On the line between two numbers |
| Street | 3 | 11 to 1 | On the outer edge of a row of three |
| Corner | 4 | 8 to 1 | On the intersection of four numbers |
| Six-line | 6 | 5 to 1 | On the outer edge between two rows |
| Red, black, odd, even, low, high | 18 | 1 to 1 | In the outside boxes |
| Dozen or column | 12 | 2 to 1 | In the outside boxes |
No bet on the layout changes the house edge. A straight-up bet and an even-money bet on the same wheel carry the same edge; they differ only in how often they pay and how much they pay when they do. What changes the edge is the wheel itself: the American layout's second green pocket increases the house advantage over the European layout on every bet that does not include it.
What the Dealer and the Table Rules Control
The dealer runs the table, but the table rules run the dealer. The minimum and maximum bet for the table are posted on a small sign, usually near the wheel or on the side of the table. The minimum applies to the total of your outside bets or to each individual inside bet, depending on the house rules, and the dealer will tell you if you ask before the first spin.
The table also has rules about when bets close, how payouts are rounded, and how disputes are handled. If a ball spins out of the wheel before landing, the dealer calls no spin and the round is replayed with all bets standing. If a chip is placed ambiguously, the dealer will ask you to clarify before the spin, because once the ball lands, the layout is settled as it lies.
Roulette is a game of independent trials. Every spin is generated by the physics of the wheel and ball, and in online roulette by a random number generator. No sequence of past numbers changes the probability of the next one. The wheel does not get hot, and the display board is not a predictor.
Three Procedural Mistakes That Cost New Players
The first is reaching for chips before the dealer has finished paying. The dealer clears losing bets before paying winners, and a hand in the layout during that process can disrupt the order of settlement. Wait until the dolly is lifted and the dealer's hands are clear of the felt before you collect anything.
The second is confusing the two wheel types when you sit down. A table with a double zero on the layout is an American wheel, and every bet on it carries a larger house edge than the same bet on a single-zero European wheel. Check the top of the grid before you buy in, because the difference is printed right there on the felt.
The third is buying in with a value you do not want to play. Once the dealer assigns a value to your colour, that value stays for the session. If you buy in for a high chip value and then want to make smaller bets, you cannot split the colour. Decide your per-chip value before you hand over your cash, and tell the dealer what you want each chip to be worth.
FAQ
Why does the roulette wheel have a zero?
The zero is the pocket that gives the house its edge. On a European wheel, the single zero means the wheel has 37 pockets but even-money bets pay as if there were 36. On an American wheel, the double zero widens that gap further. The zero is green so it stands apart from the red and black numbers.
Can I bet on the zero?
Yes. The zero sits at the top of the numbered grid and can be bet as a straight-up number, or included in splits, streets, or corners with neighbouring numbers on some layouts. It is not covered by red, black, odd, even, low, or high outside bets, which is why those bets lose when the zero lands.
Do the numbers on the wheel follow the same order as the layout?
No. The wheel is arranged so that red and black alternate and high and low numbers are distributed around the wheel in a specific sequence. The layout, by contrast, arranges the numbers in three neat columns for betting convenience. The two orders have nothing to do with each other.
