Bettors added $810,601 to Gulfstream Park's Rainbow 6 on Thursday, as they sought out a mandatory payout on the bet.
The carryover was $102,570 going into Thursday.
Calling Me Home, at 5-1, won the fifth race (first leg) by a head over Pat's Courage.
Because there is a mandatory payout, multiple tickets with winners of all six races will divide about $750,000. That is the combination of the carryover, plus 80 percent of the day's bet.
There also will not be any carryovers on the Late Pick 5, starting on the sixth race, or on the Super Hi-5 from Thursday's tenth and final race
