Four favorites and two other horses at 6-1 or lower were the winners of the last six races.
There were 272 tickets with all six winners, each receiving a non-IRS reporting $435.88.
The carryover for Thursday was $409,894. Bettors added $211,821--large for a Thursday-- to the Rainbow 6.
Because there were multiple winning tickets the carryover grew by about $50,000 and is now above $460,000.
All-sources handle on Thursday was $8,057,350, one of the largest weekday totals for the 2015-2016 meet.
Gulfstream will have 11 races on Friday, with first post of 12:35 p.m. The Rainbow 6 begins on the sixth race, with scheduled post of 3:05 p.m.
All six races in the sequence are claimers. There are 69 entrants, including also eligibles.
The Rainbow 6 is a 20-cent only per combination bet, with multiple horses permitted in each leg. For example, a ticket with two horses in each race has 64 combinations and costs $12.80.
Gulfstream pays out the full Rainbow 6 pool of the day’s bets (minus the 20 percent takeout) plus the carryover only on days when there is just one ticket with all six winners.
On other days Gulfstream divides 70 percent of the day’s bets (minus the takeout) among those bettors holding tickets with the most winners, while 30 percent (minus takeout) is added to the carryover.
Gulfstream has gone 16 straight racing programs without a single Rainbow 6 winner. It was last hit on Jan. 13, for $76,799.38.
