1963 : "Topo's game"

Rules of the Topo's game

The Topo's game has no official set of rules; there are no winners or losers, and the game itself stops when the players decide to stop.

The action consists of two players who independently manipulate a series of eight stones across a gameboard-like surface composed of different sets of parallel lines. No strategy or technique is possible, the sole object of the game being the completely subjective distribution of stones across the playing surface.
