This game is played on the following 10x10 square board:
Black's turn. Black can choose the marked stone has the pivot, and move the four stones from there until the green dot (i.e., the line of stones will land at a9,b9,c9,d9). Notice that the black stone at h9 was not part of the rotating line.
White cannot avoid Black capturing one of the two stones on the next turn, thus losing by stalemate.
The pivot and the rotating line of stones can be a subset of an entire line of stones of the same color.
There is a ZRF to play Squaredance with Zillions. A related move concept can be found at Twirls of Action.
