Rules for the Gulfstream Park Rainbow 6 can be found through the link below. This is a $0.20 base wager. For the jackpot pool to pay, there can only be one winning ticket.
The Rainbow 6 jackpot is paid out when there is a single unique ticket sold with all six winners. On days when there is no unique ticket, 70 percent of that day’s pool goes back to those bettors holding tickets with the most winners, while 30 percent is carried over to the jackpot pool.
