A parlay bet is a combination of multiple different bets into one that you stake money on all at once. If one of the bets (legs) in your parlay loses, then the whole parlay will lose. However, these are especially attractive because the odds of each leg will be multiplied by the others. To make a parlay, you can click on all the odds from each market you want to add to send them to your bet slip. In your bet slip, there will be a parlay tab which allows you to bet on all of the markets as one. With BetRivers, you can also use the Jackpot Parlay feature to automatically create parlays.
