This plug-in allows a bookie or bettor to place a Round Robin wager. A Round Robin is a multi-team wager that consists of a series of parlays. Ultimate Sports Book Manager allows you to define the number of teams that can be selected, and how many to include in each parlay. When a wager is placed, the number of teams selected is used to create all the possible parlay combinations. The amount wagered is the amount that is bet on each parlay.
