How this tool works
A Lucky 15 calculator is one of the strongest racing-tool searches in the UK. Four horses become 15 bets, so the arithmetic needs a page of its own.
Lucky 15 returns
Enter four selections and a unit stake. Mark winners to settle the 15 lines.
What is a Lucky 15?
Four selections create 15 bets: 4 singles, 6 doubles, 4 trebles and 1 four-fold. One winner still pays the single. Two or three winners keep the covering bets alive. Some shops add 10% or 25% if all four win.
FAQ
How much does a Lucky 15 cost?
15 × the unit stake. A £1 Lucky 15 costs £15, or £30 each-way.
Is a Lucky 15 better than an acca?
It costs more and pays less if all four win, but it can still return money when one or two horses lose.
Do all bookmakers pay a bonus?
No. Check the shop. This tool lets you switch the common 10% and 25% all-win bonuses on or off.
