Patent, Lucky 15, 31 & 63 Explained
Lucky bets are full-cover bets including every possible combination of your selections — singles, doubles, trebles, and accumulators. The defining feature: you get a return even if only one selection wins. This separates them from standard accumulators that require all selections to win.
The most popular is the Lucky 15 (4 selections, 15 bets): 4 singles + 6 doubles + 4 trebles + 1 fourfold. The formula: for n selections, total bets = 2ⁿ − 1. For 4: 2⁴ − 1 = 15. For 5: 31. For 6: 63.
A Patent (3 selections, 7 bets) is the smallest full-cover with singles: 3 singles + 3 doubles + 1 treble. If only one selection wins, you collect one single. Lucky bets are popular in UK horse racing — many bookmakers offer Lucky 15 bonuses such as doubling the odds if only one selection wins, or a 10–25% returns bonus if all four win.

What is a Lucky 15 bet?
A Lucky 15 covers all 15 possible combinations of 4 selections: 4 singles, 6 doubles, 4 trebles, and 1 fourfold accumulator. You get a return as long as at least one selection wins — unlike a standard fourfold that requires all four to win.
Is a Lucky 15 good value?
It depends on your selections' odds and bookmaker terms. The singles provide insurance but increase total stake to 15 units. If your selections average 5.00+ and you expect 2–3 to win, the doubles and trebles provide huge returns. For short-priced favourites at 1.5–2.0, the multiples don't compensate for the extra 14 bets.
What's the difference between a Lucky 15 and Round Robin?
A Round Robin from 4 selections uses only 3-fold parlays (4 combinations). A Lucky 15 uses ALL combination sizes — singles, doubles, trebles, and the fourfold. Lucky 15 is a true full-cover with singles; Round Robin typically refers to all same-size parlays only.
Do bookmakers offer Lucky 15 bonuses?
Yes — most major UK bookmakers offer Lucky 15 bonuses: doubling the odds on the winner if only 1 selection wins, or a 10–25% bonus on returns if all 4 win. These bonuses significantly improve expected value and can tip marginally-priced Lucky 15s into positive territory.
