four out of six consolation prize may occur. A Place Pick Nine makes up for the increased difficulty of the high number of races by allowing a second-place finish for a bettor's selected horse to count as a win. Jackpot: A twist on the traditional Pick 6 or Hi 5 bet is one where the progressive jackpot is paid only if there is one winning bet. In this case, the consolation prize is given to the multiple holders of the winning bets with the jackpot growing until there is one winner. If there is no winner when the racing season ends, a "mandatory payout" occurs typically on the last racing day where the jackpot is paid out to whoever has a winning bet.

A multi-race wheel (cf. wheel, above) consists of betting all horses in one race of a bet involving two or more races. For example, a 1-all daily double wheel bets the 1-horse in the first race with every horse in the second. People making straight bets commonly employ the strategy of an "each way" bet.

The Canadian and American equivalent is the bet across (short for across the board): the bettor bets equal sums on the horse to win, place, and show. A parlay, accumulator or roll-up consists of a series of bets in which bettors stake the winnings from one race on the next in order until either the bettor loses or the series completes successfully.
