The chip sits on the intersection of four numbers
A corner bet, also called a square bet or a four-number bet, is one of the inside bets on a roulette layout. To place it, you put a single chip on the corner where four numbers meet on the felt. The chip must touch all four corners at once. On most tables you announce the bet to the dealer or place it yourself in the online interface, and the position of the chip is what makes the wager valid.
The four numbers covered by a corner are always adjacent on the layout. A chip placed where 1, 2, 4 and 5 intersect covers those four numbers. The same logic applies anywhere on the grid: 13, 14, 16 and 17 form a corner; 28, 29, 31 and 32 form another. The bet wins if the ball lands on any one of those four numbers, and loses if it lands anywhere else.
What a win pays and why the payout is fixed
When a corner bet wins, the payout is 8 to 1. That means a winning chip returns eight times the amount wagered, plus the original stake is returned with it. The payout is fixed by the structure of the wheel, not by the operator's mood or the table's minimum.
The arithmetic behind the payout is straightforward. A corner covers four numbers. On a European wheel there are 37 pockets, so the chance of the ball landing on one of your four numbers is 4 in 37. A fair payout for that chance would be slightly more than 8 to 1, but the house pays exactly 8 to 1. The gap between the true odds and the payout is the house edge. On an American wheel with 38 pockets, the same 8 to 1 payout is paid for a 4 in 38 chance, which makes the house edge larger because the extra double-zero pocket is not compensated by any increase in the payout.
Where the corner fits among other inside bets
Roulette bets fall into two broad groups. Inside bets are placed on the numbered grid and cover specific numbers or small groups of them. Outside bets sit around the grid and cover larger categories such as red or black, odd or even, or columns. The corner belongs firmly to the inside group, and its behaviour is best understood next to the other inside wagers.
| Bet | Numbers covered | Payout | How it compares |
|---|---|---|---|
| Straight up | 1 | 35 to 1 | Highest payout, lowest chance of winning |
| Split | 2 | 17 to 1 | Covers two adjacent numbers |
| Street | 3 | 11 to 1 | A row of three numbers |
| Corner | 4 | 8 to 1 | Four numbers meeting at one intersection |
| Six line | 6 | 5 to 1 | Two adjacent rows |
The corner sits in the middle of the inside-bet range. It wins more often than a straight-up or split bet because it covers more numbers, but it pays less when it does win. It wins less often than a six line, but pays more. No inside bet is inherently better than another; each simply trades frequency of wins against size of payout, and the house edge on a European wheel is the same across all of them.
How the wheel type changes the corner bet
The corner bet itself does not change between wheel types. The chip goes on the same intersection, covers the same four numbers, and pays the same 8 to 1. What changes is the wheel underneath it.
A European wheel has 37 pockets: the numbers 0 through 36, with a single zero. An American wheel has 38 pockets: the same numbers plus a double zero. The extra pocket means every bet on an American wheel loses slightly more often, because the ball has one more place to land that is not covered by any inside or outside wager. The payout does not rise to compensate. For the same corner bet, the expected loss per unit wagered is higher on an American wheel than on a European one. This is not a matter of strategy or skill; it is built into the wheel itself, and it is the reason the wheel type is the first thing to check when you sit down.
The sequence of a round from buy-in to settlement
A corner bet is one decision inside a longer sequence, and new players make most of their procedural mistakes by treating the bet as the whole game. The round runs through several distinct stages.
First is the buy-in. At a physical table you place cash on the felt, never directly into the dealer's hand, and the dealer exchanges it for coloured chips. Online you fund your account and open the roulette table. Second is the betting window. The dealer or the interface opens betting, and you place your corner chip on the intersection. You may place several bets at once, including multiple corners, but each chip must sit cleanly on its own intersection or the dealer may interpret it as a different wager.
Third is the no-more-bets call. Once the ball is released and the dealer announces that betting is closed, you cannot touch the layout. A chip moved after the call is returned to its original position or treated as a late bet, and repeated late movement can get you removed from the table. Fourth is the outcome. The ball lands, the dealer marks the winning number, and losing bets are cleared from the felt. Fifth is settlement. Winning corner bets are paid at 8 to 1, and the original chips remain yours until you collect them or leave them in place for the next round.
Two procedural mistakes that cost new players
The first mistake is placing the chip on a line instead of a corner. A chip resting on the line between two numbers is a split bet, not a corner. A chip that is not clearly on the intersection of four numbers may be read by the dealer as a straight-up bet on whichever number it most clearly touches. The difference matters: a straight-up bet pays 35 to 1 but covers only one number, while a corner pays 8 to 1 and covers four. If you intend a corner, the chip must be unmistakably on the cross where four numbers meet.
The second mistake is assuming the payout changes with the wheel. A corner pays 8 to 1 on both European and American wheels. What changes is how often it wins, not what it pays. Players who move from a European table to an American one and expect the same rate of return are not making a strategy error; they are playing a different wheel with a different built-in edge, and the corner bet does nothing to close that gap.
What the corner bet cannot do
A corner bet is a way to cover four numbers with one chip. It is not a way to change the house edge, and no pattern of corner placements alters the mathematics of the wheel. Every spin is independent of the last, and the wheel has no memory of where the ball has landed. A corner that has not hit for twenty spins is not due to hit on the twenty-first; the chance remains 4 in 37 or 4 in 38 on every spin, depending on the wheel.
The only decisions under your control are which bets to place, how much to stake, and when to stop. The corner bet is a legitimate choice for players who want a middle ground between the long odds of a straight-up number and the frequent small returns of an outside bet, but it is a selection of risk distribution, not a method for beating the game.
FAQ
Can I place a corner bet on 0 or 00?
Yes, but only where the layout allows it. On a European wheel, 0 sits at the end of the grid and can form a corner with 1, 2 and 3. On an American wheel, 0 and 00 sit side by side and can be part of corner combinations with the adjacent numbers. The chip position is the same: it must sit on the intersection of four numbers, and the payout remains 8 to 1.
Is a corner bet better than four separate straight-up bets?
They are different ways to cover the same four numbers. Four straight-up bets on 1, 2, 4 and 5 cost four chips and pay 35 to 1 on the winning number only. One corner bet costs one chip and pays 8 to 1 if any of the four hits. The corner uses less capital per spin, while the straight-up bets return more when a specific number lands. The expected loss per unit wagered is the same on a given wheel.
Does the corner bet count toward a table's minimum bet?
At most physical tables, the minimum applies to each individual bet rather than the total across the layout, so a corner chip must meet the table minimum on its own. Online tables display their minimums in the betting interface, and some allow smaller inside bets than outside bets. The posted table rules are the authority for the table you are playing.
