It will be on races five through ten, with the sequence scheduled to begin at 2:32 p.m.
The six races have a total of 49 entries, relatively low for the Rainbow 6.
On Sunday there was just one winning Rainbow 6 ticket, paying $810,713. That was a combination of 80 percent of the day's Rainbow 6 bet and the entire carryover of $572,495.
The carryover had built up over 14 race days on which there were multiple tickets with all six winners.
The Rainbow 6 is a 20-cent per combination-only bet. Multiple horses can be used in each race, thus setting up a ticket with multiple 20-cent combinations. For example, a ticket with two horses in each race has 64 combinations and costs $12.80.
