A nicely varied collection of puzzles
A nicely varied collection of puzzles. I particularly like the way that Singmaster uses his extensive knowledge of classical collections of mathematical puzzles to expose their errors and to propose extensions. There could have been a little more care in checking -- for example, problem 13 is posed in terms of Roman numerals,1, and arithmetic operators, yet the solutions also allow the use of the Arabic digit 7. Overall, though, lots of fun.

A Collection by david Singmaster.
David Singmaster is such a talent for mathematicas and implementing that into puzzling. Metagrobology is such an xciting field for the layperson. This book is just a fantastic compilation.
