What is a Patent bet?
A Patent is 7 bets across 3 selections: 3 singles, 3 doubles, and 1 treble. It's the 3-selection version of a Lucky 15. Because it includes singles, one winner gives you a return. A £1 Patent costs £7 (or £14 each way).
Patent vs Trixie
A Trixie is the same but without the singles — just 4 bets (3 doubles and 1 treble). A Patent adds the 3 singles for 7 bets total. The Patent costs more but returns something from just one winner. A Trixie needs at least two winners.
How the Patent calculator works
How returns are calculated
Each of the 7 bets is calculated independently. Singles pay at the selection's odds. Doubles multiply two sets of odds together. The treble multiplies all three. Your total return is the sum of all 7 individual bet returns.
What happens when a selection is void
If a selection is void, it's removed from every bet it appears in. A double containing a void selection becomes a single. The treble becomes a double. Your stake is redistributed at reduced odds.
Is a Patent worth it?
Patents work well when you have three selections at decent odds (2/1 or higher). The singles provide a safety net if only one selection wins, and the doubles and treble offer meaningful returns when two or three come in. At short prices, the singles return very little relative to the £7 outlay.
