Axiom is a two player strategy game that is played in three dimensions. The board is made up of twelve cubes, six of each color. Each player has two pawns which snap into the indentations on the cubes. The object is to capture one of the other player’s pawns. On a turn, a player can move one of their pawns over the surfaces of the cubes, or move one of their cubes to change the playing surface.

At Essen 2008, a new version was released with a new physical design: smooth curved pawns, held into the indentations by magnets.
