5x15 is a solo, free, print & play game from Friedemann Friese, inspired by the solitaire “Montana”.
Your goal is to sort 75 number tiles, consisting of five colors and values from 1-15, in a play area of 5 rows and 15 columns (hence “5x15”).
You win, if you create single-colored rows with ascending numbers from 1-15.
