The game starts with an empty board. Each player has 3 stones, which are placed on the board in turn. Black starts. Once both players have all 3 stones on the board, stones can only be moved along the lines to an empty field. Forfeiting your move is not allowed, unless there is really no move possible.
You play black, the computer plays white. To put a stone on an empty field, click the field. To move a stone, click the stone. Click the button to let the computer start playing.
Note: In original Tsoro Yematatu, stones are allowed to jump over other stones. By playing it this way
however, it is possible to let games last forever, because neither player can win. That's why I adapted this rule.
