Blockdance

On each turn, the mover must identify a block of connected men of his own; name one as pivot; and rotate the block any multiple of 60º around the pivot, provided all the landing places are either empty, opponent stones, or one of his own cells that the move is just vacating.

Any opponent stones landed on are captured and removed. Passing is legal, and compulsory if no moves are legal. Winner is whoever kills all of his opponent's stones.
