Very Amusing (9), at 4-1, won Thursday's fourth race at Gulfstream to start the Rainbow 6.
The carryover coming in was $1,291.011 on the Rainbow 6, which is a 20 cent only bet.
On Thursday, bettors added $219,062 to the Rainbow 6 pool.
Paint the Corners (3) at 3-5 won the fifth race, and Queen Roller (2) at 4-1 won the sixth race.
The carryover has grown because Gulfstream has gone 29 straight race days without the jackpot/carryover payout requirement of just one ticket with the winners of all six Rainbow 6 races.
