Your Guide to the Rainbow 6 Multi-race Jackpot

If you've spent any time betting at Gulfstream Park, you've probably seen the Rainbow 6 mentioned on the tote board or in a promo for Mandatory Monday. It looks intimidating at first glance, six races, one ticket, but the mechanics are simple once you break it down. Here's what it is, when you can bet it, and how to get started.

The Rainbow 6 is a multi race jackpot bet offered at Gulfstream Park. To win, you need to pick the winner of six consecutive races in a row, usually a sequence like Races 4 through 9, though the exact legs change from day to day. It's a 20 cent maximum bet, so you can build a lot of combinations without spending a fortune, and it works the same way as the Pick 6 bets you'll find at other tracks. Gulfstream just branded theirs the Rainbow 6.

The Rainbow 6 runs every live racing day at Gulfstream Park, so it's always available during the meet. Gulfstream also runs a weekly Mandatory Monday program through the summer, where the entire pool is guaranteed to pay out that day no matter how big the carryover has grown. On these days, the 20c maximum bet is lifted. Outside of Mandatory Mondays, the pool can carry over for days or even weeks if nobody hits all six winners, and it only clears out completely on a scheduled mandatory payout date.

The Rainbow 6 exists to build a jackpot style pool that grows the longer it goes unsolved. When there's no single unique ticket with all six winners, 70 percent of that day's pool splits among the tickets with the most winners and the remaining 30 percent rolls forward into the next carryover. That structure is what lets the pool balloon into the hundreds of thousands or even millions of dollars, and it's a big part of what drives extra betting interest and bigger fields on the days it's set to pay out.

The appeal is simple. A small bet has a shot at a life changing payout if you catch a big carryover on a mandatory payout day. And even if you don't sweep all six, the consolation payouts to bettors with five winners can still be worth real money on a day with a large pool. It also rewards people who like to handicap a full card rather than a single race, since you're forming an opinion across six different spots instead of just one.

You pick one or more horses in each of the six legs of the sequence. The more horses you cover in each leg, the more it costs, since the bet multiplies out every combination you include. A common approach is to single a horse you're confident about in one or two legs to keep the cost down, then spread wider in the legs where the race looks more open.
