What is a Round Robin Bet?

A Round Robin bet creates multiple smaller parlays from a larger group of selections. Instead of needing all picks to win like a traditional parlay, you can still profit if most of your selections win - providing built-in insurance against a single losing pick.

Round Robin Strategies

Start with 2-Team Parlays

2-team parlays have the highest hit rate. They're ideal for beginners or when you're less confident in your picks.

Mind Your Total Stake

More selections = exponentially more parlays. 6 picks with all sizes can create 50+ bets. Know your total risk before placing.

Quality Over Quantity

Don't add weak picks just to increase parlays. Fewer confident selections beat many uncertain ones.

Mix Parlay Sizes

Combining 2-team and 3-team parlays gives you the best balance of safety and potential returns.
