First post is 12:35 p.m. for an eight-race card at Calder in Miami Gardens.
The Rainbow 6 is on races three through eight, with the sequence set to start at 1:35 p.m.
On Wednesday, there were 12 tickets with the winners of all six Rainbow 6 races. Each ticket was paid $1,274.02 on the 20-cent only bet.
The Rainbow 6 pool is growing because Wednesday was the fifth straight race day without the jackpot payoff requirement of just one ticket with winners of allsix Rainbow 6 races.
The jackpot consists of the entire carryover plus 80 percent of the day’s wagering on the Rainbow 6.
The carryover coming in on Wednesday was $26,432.
Bettors added $27,333 to the Rainbow 6. Gulfstream took out 20 percent of that. Per its rules on days with multiple winning tickets, it divided 56 percent of the day’s bets among the winning tickets 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.
