Mensa the High IQ Society has, in conjunction with the award winning gadget and gift specialist Wow! Stuff, launched their 2011 range of puzzle products. They are the ideal Christmas present for those that like a challenge and enjoy brain training.

The gifts include the best selling Brain Trainer,  1 Million Touch Screen Sudoku, the popular Pocket Puzzles and the handheld Electronic Chess Game.

You can purchase them directly from the Mensa Shop but many of the products are also available in High Street stores such as Sainsbury’s, WH Smith, as well as many online retailers such as Amazon or Play.com.
