For example:
Buffalo @ Cleveland -4
You bet $100.00 on Buffalo +4 (-110).
Then, on the other side you bet $90.00 on Cleveland -4 (-110) and parlay it with Cleveland ML (-210).
The total sum for these two bets is $190.00.
If Buffalo covers, you get paid $190.91 netting you $0.91.
If Buffalo doesn't cover, you win the parlay which pays $253.64 netting you $63.64.
Every sportsbook in town would have been out of business long, long ago.
