This game is played on the following square board:
The board is cylindrical, i.e., the right column is adjacent to the left column. Each player starts with 15 stones off board.
Black's turn on 2nd phase. He slides the marked stone to the green dot making a 3 in-a-row, choosing to capture the marked white stone (to prevent f1 of making a vertical 3 in-a-row on that column).
This is a modern variant of Nine Men Morris, with additional stones, a different board topology (in the original game, a Pentagon) and an extra rule (the liberty to move with less than six stones) to balance the endgame.
