A corner bet in Roulette is a type of wager that allows a player to place a bet on four adjacent numbers on the roulette table. This bet is positioned at the intersection where the four numbers meet, and it covers all of them simultaneously. When a player makes a corner bet, they place a single chip on the corner of the square formed by those four numbers. If the ball lands on any of the selected numbers, the player wins, typically receiving a payout at odds of 8 to 1. This betting strategy provides a way to increase the chances of winning as it covers multiple numbers within a single wager.
