Section 177-090-0040 - Prize Pool

(1) General: The prize pool consists of approximately sixty percent of the total amount of money wagered each week.

(2) Parimutuel: Except for the 3 of 3 and 4 of 4 prize categories, all prizes in each prize category are determined on a parimutuel basis. The prize for correctly selecting all three events in the 3 of 3 pool is $10 for a minimum $2 wager. The prize for correctly selecting all four events in the 4 of 4 pool is $20 for a minimum $2 wager.

(3) Rounding: Prize amounts are rounded down to the nearest ten cents.

(4) Carry Forward: If there is no winner in a prize category, the prize money in that category is carried forward and added to the prize pool for that prize category in the next play week. For example, if no player from all the players who played fourteen events correctly selects all fourteen winners, the money is carried forward and added to the prize pool for fourteen events in the next play week. If, in the next play week, one or more prize categories do not offer a comparable number of events, the prize pool will be carried forward to the prize category with the most events offered during that play week. For example, if the prize pool for the prize category of 12 of 12 events is carried forward to the next play week, but the largest prize category for that week is 10 of 10 events, the prize pool carried forward will be added to the prize pool for the 10 of 10 events.
