Rotation is a puzzle game on www.flash-game.net in which you can test how smart you are. You will see two circles in which there are many round faces. Each circle has some different-colored ones, and their amounts are in accordance with which level you are in. Your mission is to replace the different-colored ones in the left circle to the same position that in the right circle by rotating the faces. Remember that only when the different one and the others have formed a smaller circle can you rotate it. Good luck!
