Go is a board game for two players. The aim is to surround more territory than the opponent. This is done by moving the pieces, either diagonally, horizontally, or vertically. Each move consists of two parts: one to place a piece on an empty space and the other to pick up an object (a piece, a stone, a key, etc.) and place it on a space occupied by an object of the opponent. The object can be an empty space, an other piece, a stone, a key, or an empty space.

When there are no more moves on the board, the game ends.
