If you know somebody who's a fan of Suduko or Rubik's Cubes (or both!), this is one present they'll not be putting down anytime soon!
Sudokube, £5.95, available from www.prezzybox.com
It would seem that the Rubik's Cube has finally met its match! This six-sided cube is like the traditional Rubik's Cube but with numbers one to nine instead of colours.
