Frequently Asked Questions

What is a Patent bet?

A Patent is a system bet consisting of 7 bets on 3 selections: 3 singles, 3 doubles, and 1 treble. Because singles are included, just one winner guarantees a return.

How is a Patent different from a Trixie?

A Patent includes 3 singles that a Trixie does not, making it 7 bets instead of 4. The advantage is that one winner guarantees a return. The disadvantage is higher total stake.

Is a Patent a good bet?

Patents provide good coverage since one winner gives a return. They work best when your selections have higher odds, as the singles returns can cover the total stake even with just one winner.
