If you like math puzzles it is hard to imagine a better collection. You could irritate yourself for years.

[Peter Hughes · Rating 4 out of 5]

Exactly what it says it is, and very good too. Fun for nerds.

Deciptively tricky maths puzzles that you'd have to be a real nerd to enjoy. I am, and I loved it.

Each puzzle is concise and self contained meaning that the book is very dip-into-able to do a single puzzle when you're in the mood. The fact that the puzzles are in old-money (non-metric, Imperial, or English measurements) adds an extra little dimention of trickiness. The large number of puzzles means that this will keep me going for ages.

Definitely a challenge in mathematics.

[Paulo · Rating 3 out of 5]

This is an outstanding collection of mathematical problems and puzzles of (almost) every kind, with the solutions given at the end of the book. Some had appeared published previously and others were given here for the firts time.

Entertainment for ages.
