Maths Puzzles

I'm the puzzle adviser to the weekly international magazine New Scientist and you'll find one of my puzzles in there every couple of months.

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

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.
