Corner bets are a combination type of inside
roulette bets. With this wager you are allowed to place a bet on four adjoining numbers at once. To place a corner bet, you place your bet where the four corners of each number meet. Another name for corner bets is square bets amd quad bets because you are placing your bet in the middle of a square of 4 numbers.
After placing your corner bet, if any of your numbers hit, you are paid an 8:1 payout on your bet. If you made a corner bet of $5 and landed one of the four numbers, you would be paid a $40.
The picture below shows an example of a quad corner bet. In this corner bet, the player has placed a $100 corner bet on the numbers 25, 26, 28, and 29.
