When it comes to parlays, bettors at one of the best parlay betting sites the Rivers sportsbook can place bets of up to 12 wagers at the self-service betting kiosks or 9 wagers at the betting counters. The process is easy; just add your preferred wagers in a parlay, with the minimum being 2 wagers. The only thing with parlay betting is that it is slightly risky, given that all the individual bets you have made on a Parlay have to win before you can cash in. However, this huge risk translates into bigger returns. The only thing to remember is that in gambling, there are no guarantees; the risk-reward element is always apparent!
