5×15

About this board game

5×15 is a solo, free print-and-play game for one player that takes about 20 minutes to play. Created by Friedemann Friese, it is inspired by the solitaire game “Montana.”

The game centers on sorting 75 number tiles into a play area made up of five rows and 15 columns. The title reflects this distinctive 5-by-15 arrangement, which provides the complete space for organizing the tiles.

Every tile belongs to one of five colors and shows a value from 1 to 15. The objective is to arrange all of the tiles so that each row contains a single color and its numbers ascend from 1 through 15.
