Gulfstream Park has a Rainbow 6 carryover of $918,857 on Thursday, and on Saturday it will have a mandatory payout of the jackpot on that bet--no matter the number of tickets with the winners of all six races.
The 20 cents per-combination-only bet is on races five through ten on Friday, with the sequence scheduled to start at 2:38 p.m.
The jackpot is made up of the entire carryover plus 80 percent of the day's new Rainbow 6 bets (20 percent takeout).
If there are multiple tickets with all six winners on Thursday and on Friday, the carryover will grow to between $1.2 million and $1.3 million for Saturday.
And because the carryover "all must go" Gulfstream history indicates that between $3 million and $5 million will be bet on the Rainbow 6.
If the carryover is "taken down" on Thursday, the carryover on Saturday will probably will be about $100,000. If it is taken down on Friday there will be no Saturday carryover. In either case the "all must go" back to bettors requirement will probably generate about $1 million in bets.
On non-mandatory days, Gulfstream pays out the jackpot only if there is just one ticket with all six winners.
On non-mandatory days when there are multiple tickets with all six winners, Gulfstream takes out 20 percent and then divides 56 percent among the winning tickets while adding 24 percent to the carryover.
