First post is 12:35 p.m. for an 11-race card. The Rainbow 6 is on races six to eleven.
On the first race there will be a carryover of $2,795.58 on the Rainbow 6. It is a $1 minimum bet that requires picking the first five finishers in correct order.
The Rainbow 6 carryover has been growing because Wednesday was the seventh straight race day with multiple tickets that had the winners of all six Rainbow 6 races.
On such days, Gulfstream takes out 20 percent of the Rainbow 6 pool. It then divides 56 percent among tickets with the most Rainbow 6 winning horses and adds 24 percent to the carryover.
Gulfstream pays out the jackpot (80 percent of the day's pool plus full carryover) only on days when there is just one ticket with the winners of all six Rainbow 6 races.
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.
