The wager, dubbed the Rainbow Six, represents an innovation sweeping the sport: the microbet. Whereas the $2 bet once was the industry's standard, and most exotic wagers have been sold in $1 units, many tracks have begun to offer smaller bets. Customers at Gulfstream can play 10-cent superfectas, 50-cent Pick Fours and a 50-cent Pick Five as well as the 10-cent Rainbow Six.
