The Rubik's 3X3 Key ring puzzle plays like the original 3X3 cube. The Rubik's Cube is the classic color-matching puzzle that's a great mental challenge at home or on the move. Turn and twist the sides of the cube so that each of the six faces only has one color. Over "43 Quintillion" (that's 43 with 18 zeros to you and me) moves are possible with this original 3x3 Cube, but there is only one solution! With lots of practice you can solve it in under 10 seconds!
