It is very satisfying to get one of the puzzles right and reading Dudeney's ingenious solutions to the harder puzzles is a pleasure in its own right. One answer is calculated to 58 decimal places - not easy without a calculator unless you are HE Dudeney. I would recommend other recreational maths books such as Martin Gardner's ahead of this one, but if you're into tricky puzzles this is certainly worth buying.
A fun mathematical book

Henry Dudeney (1847-1930) was one of the inventors of mathematical puzzles. This little book can be considered a fun educational math book to encourage the use of logic and visual skills.

And if all else falls-the answers are in the back of the book. I found it to be a fun book.
