For as long as civilisations have known how to ascribe numerical values to quantities, there have been number puzzles; ancient Egyptian scrolls have been found with difficult problems for the reader to solve. Now Mensa, the leading high IQ society, have created a book which will challenge even the most adept puzzle-solver.
A wide variety of puzzle types have been included from societies around the world in The Mensa Number Puzzle Book. Each includes a historical introduction, advice on how to solve them, and even tips on how to create your own puzzles from Dr Gareth Moore, a world-renowned puzzle-setter.
