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.
Damath
The Board and Pieces
The board is similar to a checkerboard but with a twist. All even (white) tiles on the board have a mathematical symbol which dictates the operation that will be used when a player's piece captures the opponent's piece. It has numbers labeled 0-7 on its sides to determine the coordinates of the piece. Each piece of the player has corresponding values depending on what type of damath is being played. Both board and damath pieces are mostly made of thick cardboard or illustration board.
