What is Lucky 15?

A Lucky 15 is a wager on four selections that combines 15 separate bets: four singles, six doubles, four trebles and one fourfold accumulator. It is a form of full-cover bet with singles included, meaning any single winner returns money even if the other three selections lose. Bookmakers commonly attach bonuses to it, such as a double-the-odds boost when only one selection wins and a percentage bonus (often 5% to 20%) when all four win. Because every combination is covered, the stake is multiplied by 15. A £1 Lucky 15 therefore costs £15 total (£1 per bet). The bet is popular in horse racing and football, where backers want insurance against a single result letting down the whole slip. Worked example: you place a £1 Lucky 15 (£15 stake) on four horses priced at 2/1, 3/1, 4/1 and 5/1. If all four win, the singles, doubles, trebles and fourfold all land. The fourfold alone returns £1 × 3 × 4 × 5 × 6 = £360, and the full slip pays roughly £719 before any all-winners bonus; a typical 10% bonus would add about £72 on top. If only one horse wins, that single may still return with a doubled-odds bonus, softening the loss. For affiliates, Lucky 15 pages convert well because the bet is stake-heavy and bonus-driven, so clarify the exact bonus rules per bookmaker, as they vary. Compare with the Yankee (11 bets, no singles), the Lucky 31 and full-cover system bets generally.
