One highlight of Saturday's Florida Derby day card at Gulfstream Park will be a mandatory payout of the Rainbow 6 jackpot--regardless of the number of tickets with all six winning horses.
That jackpot consists of the entire Rainbow 6 carryover plus 80 percent of the day's new Rainbow 6 bets (20 percent carryover). It is a 20 cents per combination-only bet.
For Saturday there is the prospect--based on Gulfstream wagering history--that the Rainbow 6 will have a carryover in the $1 million range and that betting on the Rainbow 6 could be as much as $10 million.
Whether that happens will depend on Rainbow results on Friday, when Gulfstream will go into the day with a Rainbow 6 carryover of $871,173.
Friday is a day without a mandatory payout. So, if there are multiple tickets with all six winning horses Gulfstream will take out 20 percent of the day's Rainbow 6 bet. It will then divide 56 percent among tickets with six winners and add 24 percent to the carryover.
If Friday has just one ticket with all six winning horses, that ticket would take down the full Rainbow 6 jackpot.
In that case, there will be no coming-in carryover on Saturday. But Rainbow 6 wagering might still be around $1 million because 80 percent of the day's Rainbow 6 bets, rather than the standard 56 percent, will be paid to tickets with six winners.
Friday's Rainbow 6 is on races five through ten, with the sequence scheduled to start at 3:11 p.m.
Gulfstream will have fourteen races on Saturday, with first post of 11:30 p.m.
The Rainbow 6 will begin on the ninth race, with scheduled post of 3:37 p.m.
The Florida Derby (Grade 1) will be the 14th and final race, with scheduled post of 6:40 p.m.
Gulfstream is guaranteeing that the pools will be at least $750,000 on the Late Pick 5 and the Late Pick 4. If betting is less than $750,000 Gulfstream will put in the difference.
