Gulfstream Park will have a Rainbow 6 carryover of $734,109 on Thursday.
Gulfstream has an eight-race Thursday card with first post of 12:55 p.m. The Rainbow is on races three to eight.
The Rainbow 6 carryover is growing because Gulfstream has gone 27 racing days without the jackpot payoff requirement of just one ticket with the winners of all six Rainbow 6 races.
On Wednesday, there were 53 tickets with all six Rainbow 6 winners. Each received a payoff of $1.549.72 on a 20-cent bet.
The jackpot is the combination of the full carryover plus 80 percent of the day’s new Rainbow 6 bet (20 percent takeout).
On days with multiple winning tickets, Gulfstream takes out 20 percent of the day’s Rainbow 6 bet. It then divides 56 percent of the day’s Rainbow 6 bet among tickets with the most winners (usually six) and adds 24 percent to the carryover.
The carryover coming into Friday was $698,499. Bettors added $148,044—of which 24 percent was added 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.
HorseRacingFLA’s review of Equibase charts shows that the Rainbow 6 carryover is at its highest of the spring meet that began on April 5.
