Definition
A corner bet is a roulette wager placed on the intersection where four numbers meet on the betting layout. If the ball lands on any of those four numbers, the bet wins and pays out at 8 to 1 odds.
In context
Imagine you are at a roulette table and want to cover a small group of numbers with one chip. You place a $10 chip directly on the “cross” where the numbers 17, 18, 20, and 21 meet. If the dealer spins the wheel and the ball drops into the 18 pocket, you win $80 plus your original $10 chip back.
Why it matters
The corner bet is a popular “inside” bet because it offers a higher probability of winning than a single-number bet, while still providing a much better payout than even-money bets like Red or Black. It allows a player to cover a wider area of the layout with fewer chips.

In detail
In the world of roulette, bets are divided into “outside” bets (like Red/Black or Odd/Even) and “inside” bets. The corner bet, also known as a square bet or a “carré” in French, is one of the most efficient inside bets available. It strikes a balance between the high-volatility “Straight Up” bet (hitting one specific number) and the lower-payoff “Street” or “Split” bets.
Mathematically, a corner bet covers four numbers out of the 38 available on an American (double-zero) wheel, or four out of 37 on a European (single-zero) wheel. This gives you a 10.53% chance of winning on an American wheel and a 10.81% chance on a European wheel. Because you are covering four numbers, the payout is 8:1.
One of the common mistakes beginners make is thinking that different bets on the roulette table have different house edges. In reality, with one very specific exception (the “basket” bet on an American wheel), every single bet on a roulette table has the exact same house edge: 5.26% for American and 2.70% for European. This means that over the long run, the casino expects to keep roughly $5.26 out of every $100 you bet on corners, just as they would if you bet only on Red.
The strategy behind using corner bets often involves “clustering.” Experienced players might place several corner bets to cover a specific section of the wheel. For example, if you place four corner bets, you are covering 16 numbers. If the ball lands in any of those 16 pockets, you win 8 units while losing the other 3 units placed on the losing corners, netting a 5-unit profit. This is a common way for players to manage their bankroll while still chasing the excitement of inside-number wins.
From the dealer’s perspective, the corner bet is one of the easiest to identify but one of the most common spots for “payout disputes.” Because the chip is placed on the intersection of four lines, a chip that is slightly off-center can lead to confusion about whether it was intended to be a “Split” bet (covering two numbers) or a “Corner” bet. This is why professional dealers will often “center” the chip with their finger or a marker if it looks ambiguous before they spin the wheel.
Another aspect of the corner bet is its role in “completion” bets in high-stakes rooms. A player might ask for a “complete bet” on a number like 17. This means the dealer will place every possible bet that includes the number 17: the straight-up 17, the four splits that include 17, and the four corners that include 17. This highlights how the corner bet is a fundamental building block of complex roulette strategies.
Ultimately, the corner bet is for the player who wants more frequent wins than the “Straight Up” bet provides but isn’t satisfied with the slow grind of the outside even-money bets. It provides enough of a “pop” in the payout to make a $5 or $10 bet feel significant when it hits, making it a staple of the casual and professional roulette experience alike.
