Gulfstream is guaranteeing that Thursday's jackpot pool will be at least $400,000 if there is just one ticket with all six winners.
The jackpot is made up of the entire coming in carryover and 80 percent of the day's new Rainbow 6 bet. If Thursday's total is less than $400,000 and there is just one winning ticket, Gulfstream will make up the difference.
