I like Round robins. I prefer straight bets, but you can pick three teams and do parlays in combination of two. They always offer 2's and a 3. I usually just do the two team combos. If you hit two out of three, you basically break even (small loss). Lose two games and all tickets are done.
Say you bet $100 on a round robin (2's) Risk $300 to win $780. If you win two games out of three, you would have a net loss of $40.
Games A-B-C
A A C
B C B
If you bet $100 on each game straight up, you would make a profit if you win two. Max upside if you hit all three straight bets would be $300 vs $780 on the round robin.
I've never done one on game qtrs and don't know if it's allowed. Looks good at 1/2 , but have a qtr with no score and chance of profit is gone. gl
