The person at the wheel is the croupier
If you are standing at a roulette table wondering who is in charge of the spin, the answer is the croupier. In some casinos the same person is called a dealer, but the role is identical: this is the employee who runs the game, handles the bets, sends the ball around the track, and settles every winning and losing wager. The croupier is not a player, has no stake in the outcome, and does not choose where the ball lands. Their job is to run the round in a fixed sequence so that every player at the table sees the same procedure.
A roulette table usually has more than one staff member. One croupier runs the wheel and the ball. A second, sometimes called a table supervisor or inspector, watches the layout, confirms payouts, and resolves disputes. On busy tables you may also see a pit boss standing behind the action, overseeing several tables at once. None of these people can influence the result of a spin in normal play; their function is to keep the game moving and to make sure bets are placed, paid, and recorded correctly.
What the croupier does during a round
A round of roulette has a rhythm, and the croupier controls it from start to finish. The sequence matters because every bet must be placed before the ball drops, and every payout must be made before the next spin begins. Here is the standard flow.
- Opening the betting window. The croupier announces that bets are open, usually with a phrase like "place your bets," and players put chips on the layout.
- Closing the betting window. At a set moment the croupier calls an end to betting, often with a hand motion and the words "no more bets." After this point no chip may be touched on the layout.
- The spin. The croupier sends the ball around the outer track in the opposite direction to the spinning wheel. The ball loses speed, drops onto the rotor, bounces across the frets, and settles in a numbered pocket.
- Marking the winning number. The croupier places a marker, sometimes called a dolly, on the winning number on the layout. This freezes the table so no one can move chips while payouts are calculated.
- Settling bets. Losing bets are cleared first, then winning bets are paid. The croupier works through the layout in a fixed order, stacking chips beside each winning wager.
- Reopening the table. Once all bets are settled and the dolly is removed, the next betting window opens and the cycle repeats.
Every step is visible. If you are new to the table, watch one full round before you buy in. It will answer most questions about when to bet, when to stop touching your chips, and how payouts are handled.
Buying in and getting chips
Roulette players do not bet with regular casino chips at most tables. They use special roulette chips, each player receiving a distinct colour so that bets on the shared layout can be told apart. You buy these at the table, not at the cashier. Place your money on the felt rather than handing it directly to the croupier, and state the denomination you want. The croupier will exchange it for a stack of colour chips and announce the value of each chip aloud.
These chips have no value away from the roulette table. When you finish playing, the croupier converts them back into standard casino chips or cash. Do not walk away from the table with colour chips still in your hand; another table will not accept them and the cashier cannot redeem them.
The bets on the layout and how their edges differ
Roulette looks simple because the objective is just to predict where the ball will land, but the layout contains many different bets, and they do not all lose money at the same rate. The wheel itself is the first variable. A European wheel has 37 pockets with a single zero. An American wheel has 38 pockets with a single zero and a double zero. The extra pocket on the American layout increases the house edge on every bet that does not specifically account for it.
The table below compares the main bet categories. The point of the comparison is not that one bet is a path to profit; every bet on the wheel carries a built-in house edge. The point is that some bets lose more slowly than others, and the difference is large enough to matter over a long session.
| Bet type | What it covers | Payout structure | How the edge compares |
|---|---|---|---|
| Even-money bets | Red/black, odd/even, high/low | 1 to 1 | Among the lowest-edge bets on the table |
| Dozens and columns | 12 numbers each | 2 to 1 | Edge sits between even-money and single-number bets |
| Six-line | 6 numbers | 5 to 1 | Higher edge than dozens, lower than straight-up |
| Straight-up | 1 single number | 35 to 1 | Highest edge among standard inside bets |
On a European wheel, a straight-up bet pays 35 to 1 even though there are 37 pockets. That one-pocket shortfall is the house edge expressed as a payout. On an American wheel with 38 pockets the same 35-to-1 payout leaves a wider gap. The croupier does not set these odds; they are printed on the layout and fixed by the wheel configuration.
Some tables also carry announced bets, sometimes called call bets or French bets, which cover fixed sections of the wheel such as a group of neighbours around a chosen number. These are more common on European tables. If a table offers them, the croupier places the chips on your behalf according to the table's published pattern.
Three procedural mistakes new players make
Most mistakes at a roulette table are not about choosing the wrong number. They are about timing and chip handling, and the croupier will correct them the same way every time.
- Betting after the call. Once the croupier says "no more bets," nothing may be placed or moved. A chip that lands on the layout after the call is returned or treated as a late bet, and the player is told to wait for the next round.
- Touching chips after the ball has dropped. When the dolly is on the winning number, the layout is frozen. Moving a chip during settlement looks like an attempt to alter a bet, and the table supervisor will intervene even if the movement was innocent.
- Leaving with colour chips. Roulette chips only work at the table that issued them. Cashing them at the cage is not possible, and another table will refuse them. Convert them before you step away.
None of these errors affect the odds, but all of them slow the game or create suspicion. The croupier's instructions are not suggestions; they are the operating rules of the table.
What the croupier cannot do
It is worth being direct about this because the question "who is the roulette spinner" sometimes carries a second, unspoken question: can that person control the result? The honest answer is that the croupier's influence is procedural, not physical. The wheel spins freely, the ball travels the opposite way around the track, and the outcome is determined by the interaction of the wheel, the ball, and the frets. A croupier is not aiming for a number, cannot see the future, and has no reason to steer a result toward or away from any particular player.
Casinos also monitor the wheel and the staff. A table supervisor watches every payout, and the pit boss watches the table supervisor. The wheel itself is checked for balance and wear, and any anomaly is investigated. This does not make roulette a game where the player has an edge; it makes it a game where the procedure is consistent and the house edge is built into the payout schedule rather than into the conduct of the spin.
FAQ
Is the croupier the same as the dealer?
Yes. In roulette the two words are used interchangeably. The term croupier is more common in European and high-limit rooms, while dealer is more common in American casinos, but the duties are the same: running the wheel, managing the bets, and settling the payouts.
Can I ask the croupier to spin the wheel in a certain direction?
No. The direction of the wheel and the ball follows the house procedure, and the croupier will not take requests. The spin is not a service you can customise; it is a fixed part of the round that runs the same way for every player at the table.
Why does the croupier clear losing bets before paying winners?
Because it keeps the layout clean and the accounting clear. Removing losing chips first leaves only winning wagers on the felt, so the croupier can work through the payouts without confusion. It also prevents a player from grabbing a losing chip while the table is being settled.
