Tapatan
Tapatan is a two-player abstract strategy game from the Philippines. It is related to tic-tac-toe, but even more related to Three Men's Morris, Nine Holes, Achi, Tant Fant, Shisima, and Dara, because pieces are moved on the board to create the 3 in-a-row. It is an alignment game.
Tapatan is identical to the 3 piece version of Achi.
