A Lucky 15 is a 4-selection combination bet that includes 15 total wagers: 4 singles, 6 doubles, 4 trebles, and 1 four-fold accumulator. It gives you more ways to cash than a straight parlay, while still letting the upside build if multiple picks win.
Enter 4 American-odds selections and your stake per line. The calculator converts each leg to decimal odds, builds every single, double, treble, and the four-fold, then totals the projected return and profit.
If your stake per line is $1, your total Lucky 15 stake is $15. If it is $2, the total stake is $30. This is where people occasionally realize they liked the idea of a Lucky 15 more than the invoice.
