Patent Bet Calculator
A Patent covers 3 selections across 7 bets: 3 singles, 3 doubles, and 1 treble. Because singles are included, just one winner from your three selections is enough to get a return.
Bet Calculator
3 selections: 3 singles + 3 doubles + 1 treble. 7 bets. Any 1 winner gives a return.
Enter valid odds for every selection (e.g. 5/1 or 6.0).
Figures shown are standard returns and don't include bookmaker-specific bonuses (e.g. some firms pay a bonus on a full Lucky 15/31/63 winning line, or double the odds on a Lucky 15 with a single winner). Always check your bookmaker's exact terms.
How It Works
Enter odds for your three selections and set a unit stake. The calculator generates all 7 lines automatically, marks each combination as it resolves, and totals stake, return and profit.
Bet Structure

Pro Tip
A Patent is a good choice when you fancy three horses but are not confident all of them will win — the built-in singles mean a lone winner still shows a return, unlike a Trixie which needs at least two.
