What Is a Corner Bet in Roulette?
A corner bet is an inside roulette wager covering four adjoining numbers that form a square on the betting layout. One chip placed at their shared intersection wins when the ball lands on any covered number and pays 8:1. For example, the junction of 1, 2, 4 and 5 covers all four outcomes. The chance is 10.81% on a 37-pocket European wheel and 10.53% on a 38-pocket American wheel. Canadian players can use this glossary to understand chip placement, total returns, house edge and why provincial platform rules and table limits still apply.
How a Corner Bet Works on Roulette Layouts
A corner bet covers exactly four adjacent numbers arranged as a two-by-two square. It is an inside bet because the chip sits within the numbered grid, at the point shared by all four selections. The combinations are fixed by the layout; players cannot group four unrelated numbers. A chip on the junction of 8, 9, 11 and 12, for example, wins when any one of those pockets appears. The standard payout is 8:1, and the original stake is also returned.
Placing a Corner Bet
Place one chip on the cross where four number boxes meet. At a live table, the dealer accepts the wager until betting closes; in digital roulette, selecting the junction highlights the four covered numbers before confirmation. Multiple corners may be played in one spin, subject to the table’s minimum and maximum limits, but overlapping wagers increase the total amount at risk. Check the bet panel carefully on mobile screens because a nearby tap could register a split, street or six-line bet instead. Licensed Canadian-facing platforms should display stake limits and the selected wager before the spin begins.
Corner Bet Probability, Returns and House Edge
A winning corner pays 8:1. A $10 CAD wager therefore produces $80 in profit and a $90 total return after the stake comes back. Win probability equals covered pockets divided by all wheel pockets: 4/37, or 10.81%, in European roulette and 4/38, or 10.53%, in American roulette. The corresponding house edge is 2.70% and 5.26%, respectively, because zero—and double zero on the American wheel—remain losing outcomes. Every standard wager on the same wheel carries that base edge, so covering four numbers changes hit frequency and payout variance, not the long-run mathematical advantage. Each spin remains independent.
