A corner bet is a roulette wager on four numbers that touch at one shared corner on the layout. The chip is placed at the intersection of those four numbers. If any one of the four numbers hits, the bet usually pays 8 to 1.
Plain Talk
A corner bet is also called a square bet. It covers more numbers than a straight-up, split, or street bet, so it wins more often than those smaller inside bets. The tradeoff is simple: the payout is lower.
On a standard layout, a chip placed at the corner shared by 1, 2, 4, and 5 covers all four numbers. A different corner position covers a different group of four.

| Term | Plain-English meaning | Where it appears | Why it matters |
|---|---|---|---|
| Corner bet | Four-number inside bet | Number grid intersections | Covers a small square of numbers |
| Square bet | Another name for corner bet | Dealer/player language | Same bet, different wording |
| 8 to 1 | Usual payout | Roulette paytable | Payout is below true odds because of zero |
| Inside bet | Bet placed on the number grid | Roulette layout | Corner bets are part of this category |
Where You See It
You see corner bets on the inside betting grid. The chip is placed on the crossing point where four number boxes meet. In live roulette, a dealer may call the bet a corner or square. In online roulette, the interface usually highlights the four covered numbers when the cursor or finger touches the position.
Why It Matters
A corner bet matters because it is one of the cleanest examples of roulette payout design. The bet covers four numbers and pays 8 to 1, but the true odds are not exactly 8 to 1 once the zero pockets are included.
That gap is the house edge. The corner bet does not become better because it covers more numbers. It simply changes how the wins and losses feel.
Example
A player places $5 on the corner covering 14, 15, 17, and 18.
If the ball lands on any of those four numbers, the player wins $40 profit plus the original $5 stake. If the ball lands anywhere else, including 0 or 00, the $5 is lost.
On a European wheel, the bet has 4 winning pockets out of 37. On an American wheel, it has 4 winning pockets out of 38.
From the Casino Side:
From the casino side, corner bets are routine but easy to misread when the layout is crowded. A chip near a line can create claims after the result: was it a split, corner, street, or six-line? Dealers are trained to place, read, and clear these bets cleanly because small placement errors can become payout disputes.
For management, corner bets are not a special risk category. They are part of normal inside-bet action. The casino tracks roulette performance through drop, win, game speed, and hold, not by treating each corner as a separate game.
Common Misunderstanding
Players often think a corner bet is safer because it covers four numbers. It is safer only in the sense that it wins more often than a one-number bet. It is not safer in the house-edge sense.
Another misunderstanding is layout superstition. Four numbers touching on the felt do not form a special group on the wheel. Roulette wheel order and table layout are different things.
Hard Truth
A corner bet gives you more ways to hit, not a better price on the wheel.

Deeper Insight
The corner bet is a useful way to understand the difference between hit frequency and expected value. Four covered numbers feel more active than one or two covered numbers, but the zero pocket or pockets still pull the payout below true odds.
Formula / Calculation
| Wheel | Winning numbers | Usual payout | House edge |
|---|---|---|---|
| European roulette | 4 / 37 | 8 to 1 | 2.70% |
| American roulette | 4 / 38 | 8 to 1 | 5.26% |
Expected value for a $1 American corner bet:
EV = (4/38 × $8) - (34/38 × $1)
EV = -$0.0526
Formula Explanation in Plain English
Four pockets win $8. The other pockets lose $1. On an American wheel, the two zero pockets help create the 5.26% house edge even though the bet covers more numbers than a split or street bet.
