I have to back to school to understand these rules....
.......... Churchill will offer Pick 6 wagers on Kentucky Oaks Day and Kentucky Derby Day at a $2 minimum.
The jackpot, 20-cent minimum Single 6 wager, in which the full jackpot is paid only if there is a single winner, will begin at the start of the meet and continue throughout, with a forced payout on the meet's final day of racing. The track also could set mandatory payout days before the meet's close and will inform the racing commission and public in advance of such decisions.
This new approach to the jackpot Single 6 wager will end the previous option to transfer carry-over from Churchill's $2 Pick 6 wager offered during Derby week to the Single Six Jackpot pool.
