Betting a round robin in sports involves creating multiple parlay bets from a selection of teams or outcomes. Here’s a step-by-step guide on how to do it:

1. Select Your Games: Choose the games or events you want to bet on. For example, let’s say you’re interested in betting on three football games: Game A, Game B, and Game C.
2. Choose Your Bet Types: Decide on the type of bet you want to make for each game. Common options include Moneyline (picking the winner), Point Spread (handicap betting), and Over/Under (betting on the total score).
3. Create Your Parlays: With a round robin, you’ll be creating multiple parlays with the games you’ve chosen. For three games (A, B, and C), a round robin would create three two-team parlays: AB, AC, and BC.
4. Calculate the Number of Bets: In this example, you’d be making three parlays, each with two teams. So, you’d be placing a total of three bets.
5. Determine Your Stake: Decide how much you want to bet on each parlay. Your total stake will depend on how much you wager on each individual bet.
6. Place Your Bets: Once you’ve decided on your bets and stake, you can place them with your chosen sportsbook. Make sure to double-check your selections before confirming.
7. Track Your Bets: Keep track of the progress of each parlay as the games unfold. You’ll need at least two of your selected teams to win in order to have a winning parlay.
8. Collect Your Winnings: If your parlays are successful, you’ll collect winnings based on the odds of each individual bet within the parlay.

Round robin betting allows for flexibility and can mitigate some of the risks associated with traditional parlays, as you’re not entirely reliant on every single bet winning to generate a return. However, it’s essential to understand that the more bets you include in a round robin, the higher your overall stake will be, and the more complex it can become to track and manage your bets.
