Rubik's cube has six different coloured sides, each made up of nine squares. Once the faces are jumbled up, you have to twist and twirl them to return each coloured square to its place. Sounds pretty simple? You'd be surprised!

There are... wait for it... 43,252,003,274,489,856,000 ways of arranging the squares, and only one of these is the solution. So it's a massive challenge to work it out completely on your own. Fortunately, this time round each cube comes with a fantastic games and solution booklet which shows you how to solve the cube and all about the games you can play including speedsiding: how fast can you solve one side of your cube.
