Frequently Asked Questions
What exactly is a Patent bet?
A Patent is a 7-bet system built on 3 selections: 3 singles, 3 doubles, and 1 treble. Since singles are included, just one winner guarantees a return.
How does a Patent differ from a Trixie?
A Patent throws in 3 singles that a Trixie skips, making it 7 bets rather than 4. The upside: one winner guarantees a return. The downside: a bigger total stake.
Is a Patent a smart bet?
Patents give solid coverage because a single winner pays. They shine when your selections carry higher odds, since the singles returns can claw back the total stake off just one winner.
