A Round robin is a combo of parlays, you are betting all possible parlays for a certain number of teams.
A 3 team Round robin of two team parlays with Detroit -6.5, Boston +8, and Miami -1. This round robin gives you 3 two teamers. Detroit to Boston, Detroit to Miami, Boston to Miami. The bets are graded like you bet all spearately. Like Fishhead said: hit 1 out of 3 lose 3 bets, hit 2 out of 3 lose two, win one parlay, hit all 3 you win 3 parlays. Remember when you win, you are winning parlays, 13-5 for two teamers (laying -110).
