How a Lucky 15 differs from a Yankee
Both products use four selections and include every double, treble and the fourfold. A Lucky 15 adds four singles, increasing the ticket from 11 to 15 independently settled bets.
Why the singles matter
Each selection has its own single, so a winning selection can produce a return even when other selections prevent the larger combinations from winning.
Stake per line or total ticket
Stake per line applies the amount to all 15 bets. Total-ticket mode allocates the entered total deterministically across every constituent line.
Supplied voids and neutral adjustments
Voids and supported adjustments are applied only where supplied and remain visible on affected lines. SlipLogic does not add bookmaker-specific Lucky 15 bonuses.
All fifteen lines stay inspectable
Singles, doubles, trebles and the fourfold remain in canonical order with their own stake, price, settlement explanation and return.
