Maths Puzzles

On the left are a few puzzles that I enjoyed when I first came across them. None of them is a 'cheat', though they all require an element of what might be described as lateral thinking to solve them.

To try a particular puzzle just click on the name.

From 2019 to 2023 I edited the weekly Headscratchers column for the international magazine New Scientist.  I co-edited a compilation of some of the best puzzles from the column in a book that year, more details in my book section.

I also write an occasional blog about puzzles that I have found particularly interesting. You can visit it HERE
