Author's Description:

Your goal is simple. Destroy red in as few moves as possible. When you click a stone, it rotates clockwise. The stone that it points to is converted.

For each stone involved, any stone that is either pointed at or is pointing to a green stone will be converted.
The rules are simple. The strategy required is not.
Good luck playing the game.
