Of course, the more bets you add, the likelier it is the parlay doesn't succeed. The payout can grow as much as you want it if you keep adding bets, as a lot of sportsbooks allow up to 10-bet parlays or even up to 15. If you bet $50 on each of those moneyline odds, the payout would be about $174. In a parlay, those odds would turn into +205, which means a $100 bet would pay out $305. Instead of betting one team at -150 to win and the other at -120, you could combine them. For example, if you really like two teams to win, you can combine their moneylines into a parlay bet. The main reason to parlay bets is because the payout can turn into much more money than a single bet. A parlay is a bet on two or more point spreads, over/unders or moneylines to increase the possible payout
