First post is 12:35 p.m. for a ten-race card. The Rainbow 6 is on races five through ten, with a carryover that is now into its 14th day.
Friday will be the last day prior to Saturday's mandatory jackpot payout of the carryover and 80 percent of the day's new Rainbow 6 bets--regardless of the number of tickets with the winners of all six Rainbow 6 races.
With the exception of mandatory payout days, Gulfstream makes that jackpot payout only if there is just one ticket with all six winners.
On Saturday, that payout can be divided among multiple winners. The pie could be huge,based on expectations that $1 million or more will be bet on the Rainbow 6 on Saturday.
On Thursday there 35 tickets with all six winners. Each was paid $2,858,68.
The carryover coming into Thursday was $300,099. Bettors added $181,040 to the Rainbow 6, the most on any day through 17 days of the championship meet.
Gulfstream took out 20 percent of the day’s Rainbow 6 bet and then divided 56 percent among tickets with the most winning horses (in Thursday’s case six) and added 24 percent to the carryover.
The Rainbow 6 is a 20-cent per combination-only bet. Multiple horses can be used in each race, thus setting up a ticket with multiple 20 cent combinations. For example, a ticket with two horses in each race has 64 combinations and costs $12.80.
