A round robin bet is a bet that has at least three elements. It’s the most complete bet slip that exists. It has several combinations of bets on a single, unique bet slip.
This type of bet is much less risky than a parlay bet, as you have room for error. Even if one of your bets is wrong, you can still win.
Example: You want to bet on the Celtics, Bucks and Knicks winning. If you make a parlay bet, all three teams must win the match for you to win the bet. However, if you place a round robin bet of two out of three, you will win if at least two of your bets are winning.
