Gomoku
Gomoku, also called "Five in a Row", is an abstract strategy board game. It is traditionally played with Go pieces (black and white stones) on a Go board, using 15×15 of the 19×19 grid intersections. Because pieces are not moved or removed from the board, Gomoku may also be played as a paper-and-pencil game. The game is known in several countries under different names.
Dao (game)
It comprises a 4x4 playing board with four playing pieces for each player. The aim of the game is to arrange pieces in certain winning formations before the opponent can. It is unique because any piece that is moving must move as far as it can.
