Round robins are bets where you pick 3 to 8 teams and match them in as many 2-, 3- or 4-team combinations as possible.
When you place a round-robin wager, you aren’t allowed to keep open spots.
Example:
Bills -5, Patriots +2.5, Saints +7
Possible combinations are:
2TP | 2TP | 2TP |
Bills -5 | Bills -5 | Patriots +2.5 |
Patriots +2.5 | Saints +7 | Saints +7 |
Note: Playing this round-robin for $100 involves putting $100 on each possible 2-team parlay combination, for a total ticket of $300.
