Start with the felt, not the wheel
Most new players walk up to a roulette table and look at the spinning wheel first. The part you interact with is the printed felt in front of you, and knowing how that layout is organised answers most of the placement questions before they come up. The felt is divided into two zones: an inside area built around the numbered grid, and an outside area wrapped around it with boxes for broader groups of numbers. Every chip you place lands in one of those two zones, and the zone determines how the bet pays and how much risk it carries.
The numbered grid runs from 0 to 36, laid out in three columns of twelve numbers each. On a European wheel the grid shows a single zero at the top of the columns; on an American layout there is a zero and a double zero side by side. The outside boxes sit beyond the grid and cover categories like red or black, odd or even, and the low and high halves of the numbers. Your first job at the table is not to pick a number but to decide which zone matches how you want to play.
How a round moves from buy-in to settlement
You cannot place chips directly on the felt with cash. At a live table, you buy in by putting money on the table in front of you, never into the dealer's hand. The dealer exchanges that cash for wheel chips, which are colour-coded to you so the staff can tell your bets apart from everyone else's. At an electronic or online table, the screen does this automatically when you load a balance.
Once you have chips, the sequence is simple. The dealer opens the betting window, you place chips on the layout, and the dealer closes the window with a clear call or a hand motion. After that point no chip may be moved, added, or removed. The ball is spun, it drops into a pocket, and the dealer marks the winning number on the felt. Losing bets are cleared first, then winning bets are paid. You collect your chips only after the payout is complete, and the next round begins when the dealer reopens the window.
Inside bets: chips on the numbered grid
Inside bets are any chips placed on the numbered grid itself, including the lines and corners around it. They cover one number or a small cluster of numbers, so they pay more when they hit and miss more often. The placement rules are precise because the dealer must be able to read your bet without asking you what you meant.
A straight-up bet is a chip placed entirely inside one number's box. A split bet sits on the line between two adjacent numbers, covering both. A street bet goes on the outer edge of a row, covering all three numbers in that row. A corner bet sits on the intersection of four numbers. A six-line bet covers two adjacent rows and goes on the outer corner where those two rows meet. On layouts with a zero, special placements cover combinations that include the zero, and the printed felt shows exactly where those chips go.
| Inside bet | Where the chip goes | What it covers |
|---|---|---|
| Straight-up | Fully inside one number's box | One number |
| Split | On the line between two numbers | Two adjacent numbers |
| Street | On the outer edge of a row | Three numbers in one row |
| Corner | On the intersection of four numbers | Four numbers |
| Six-line | On the outer corner of two rows | Six numbers across two rows |
If you are unsure about a placement, ask the dealer before the spin. A chip placed ambiguously will be interpreted according to the house rules printed at the table, and that interpretation may not match what you intended.
Outside bets: chips in the surrounding boxes
Outside bets sit in the boxes around the numbered grid. They cover larger groups of numbers, so they hit more often and pay less per hit. The placement is simpler because each box is labelled, and a chip anywhere inside the box counts.
The even-money outside bets are red or black, odd or even, and the low or high half of the numbers. On a European wheel the low half runs 1 to 18 and the high half 19 to 36; on an American wheel the same split applies, but the zero and double zero belong to neither half, neither colour for those pockets, and neither odd nor even. That is why an even-money outside bet is not a true fifty-fifty proposition even though it pays one to one. The zero pockets are the reason the bet loses more often than it wins over a long series of spins.
The other outside bets are the dozen boxes, which cover twelve numbers each, and the column boxes at the foot of each of the three columns. A chip in a column box covers all twelve numbers in that column, including the zero if the zero sits at the top of that column on the printed layout.
What changes between the two wheel types
The placement rules are the same on both main layouts, but the number of pockets changes what your chip is up against. A European wheel has 37 pockets with a single zero. An American wheel has 38 pockets with a zero and a double zero. The extra pocket does not change where you put your chips; it changes how often any given placement wins.
Because the double zero belongs to no outside category, every outside bet on an American layout loses on two pockets instead of one. Inside bets face the same issue: a straight-up number still covers one pocket, but there is one more pocket that is not your number. The house edge on the American layout is higher for the same bet, which is why the wheel type matters more than the colour of the chips in front of you. If the table offers a choice, the European layout is the gentler place to put the same chips.
| Feature | European wheel | American wheel |
|---|---|---|
| Pockets | 37 | 38 |
| Zero pockets | One | Two |
| Outside bet exposure | Loses on one zero | Loses on two zero pockets |
| House edge on same bet | Lower | Higher |
The procedural mistakes that cost new players
The first mistake is buying in with cash handed to the dealer. The dealer cannot take money from your hand; it must go on the felt so the cameras and the floor staff can see the transaction. Put the cash down, state the denomination you want, and let the dealer handle the exchange.
The second mistake is moving chips after the dealer has closed the betting window. Once the call is made, the layout is frozen. Touching a bet after that point looks like an attempt to change it, even if you only meant to tidy the stack. Make your placements early and leave them alone.
The third mistake is placing an inside bet without knowing what it covers. A chip that straddles a line covers the numbers on both sides, not the one you were staring at. If you want a single number, the chip must be fully inside that number's box. When in doubt, place it plainly and confirm with the dealer before the spin.
FAQ
Can I place chips on the roulette table after the ball is spinning?
No. The dealer closes the betting window before the spin, and once it is closed no chips may be placed, moved, or removed. The window may stay open for a moment while the ball is in motion at some tables, but the dealer's call is the only signal that matters. Place your bets early and stop touching the felt when the window closes.
What happens if my chip lands on a line by accident?
The dealer will read it as the bet that best matches where the chip sits, according to the house rules. A chip on the line between two numbers is a split bet covering both, not a mistake the dealer will correct. If you intended a single number, place the chip fully inside the box and confirm before the window closes.
Do outside bets go in a different place online?
The layout is the same, but the screen shows the boxes as clickable areas. You select a chip value, then tap or click the box or number you want. The software confirms the bet before the spin, and the same rule applies: once the round locks, you cannot change the placement.
