Why not challenge a friend to play this transformation game?
Players take it in turns to move. When it is a player's turn, s/he must try to move the playing piece from where it is on the board to another of the marked triangles. S/he must use a transformation or combination of transformations corresponding to one or more of the cards in his/her hand. In the case of more than one card, the intermediate positions of the playing piece need not correspond to a marked triangle.
