Yamma (山) is an abstract strategy game inspired one of the classics - Connect Four.

The goal still the same; make a line of four-in-a-row of your color and win. The twist here is that the rotating board of Yama contains triangular slots that stand the cube up on its corner - revealing three sides, each of which can be seen from a different point of view. And it is in one of these three point-of-views in which you must try to form your line of four-in-a-row.
