The Rubik's Cube is the classic colour-matching puzzle that's a great mental challenge. Turn and twist the sides of the cube so that each of the six faces only has one colour. Over 43 Quintillion (that's 43 with 18 zeros!!) moves are possible with this original 3 x 3 Cube, but there is only one solution! With lots of practice you can solve it in under 10 seconds! Rubik's Cube is the incredibly addictive, and has fascinated fans since it arrived in 1980. 8+ years.
