What is the difference between a tricast and a trifecta?

A tricast is a bookmaker bet where dividends are calculated using the Computer Straight Forecast formula after the race. A trifecta is a pool bet offered by the Tote, where all stakes go into a shared pool from which a 25% deduction is taken before returns are divided among winners. Both require predicting the first three finishers in exact order, but their payout mechanisms differ fundamentally.

How is a tricast payout calculated?

Tricast dividends are calculated using the Computer Straight Forecast (CSF) formula, introduced in 1977 to standardise returns across bookmakers. The exact algorithm is proprietary and unpublished, but known factors include the starting prices of all runners, the SP of the first three finishers specifically, the position of the favourite, race type, and draw bias characteristics of the course.

What happens to my tricast bet if there is a non-runner or dead heat?

If one of your tricast selections becomes a non-runner, your bet converts to a straight forecast on the remaining two horses. If two selections withdraw, the bet becomes a win single on the remaining horse at starting price. If all three selections withdraw, the bet is void and your stake is returned.
