16!

The game itself is simple. 16 tiles are played from a pool of tiles. The player unable to play a tile loses. There are several rules about playing a tile, but it is basically like dominoes. The 16 tiles each are laid out with a 3x3 grid which can or can not have a pip in each spot in the grid, but the center spot never has a pip in it. There are none to eight pips along the edges of the tiles.
