Zen is a stacking game -- or tower building game -- where players stack inverted funnels on top of one another.

Before placing a new piece, the active player can actually manipulate the stack in the hopes of achieving the proper balance in preparation for the play.

Multiple Zen sets allow for players to race against one another to see who can get the highest stack in the allotted time.
