Also on Thursday, Gulfstream in its first race will have a carryover of $11,570.39 on its Super Hi-5.
There will be nine races with first post of 1:15 p.m.
There is a carryover on the Super Hi-5, a $1 minimum bet, because on Sunday's last two races there were no tickets with the first five finishers in correct order.
There are no consolation payoffs on the Super Hi-5, such as four of five. So, the entire pool rolls over to Thursday's first race.
It is five furlongs on turf for fillies and mares 3-years-old and up, with an $18,000 purse and a $12,500 claiming price. There are seven entrants.
Gulfstream has the Super Hi-5 on all races with seven or more starters.
Bettors will have three days to handicap the race. In similar carryover situations this year, bettors have wagered $50,000 or more on the Super Hi-5.
The Rainbow 6 carryover is growing because Sunday was the sixth straight day without the jackpot/carryover payoff requirement of just one ticket with the winners of all six Rainbow 6 races.
On Sunday there were 13 tickets with all six winners. Each paid $2,719.40.
The carryover going in was $53,523. Bettors wagered $63,147 on the Rainbow 6. Gulfstream took out 20 percent of that money, distributed 56 percent among holders of winning tickets and added 24 percent to the carryover—growing it to $68,674.15.
