Hi all, Due to the success of the Cheryl’s birthday logic problem last week in the Guardian (my two stories received well over 5 million views, making it the biggest story of the week), the paper has asked me to curate a maths puzzle slot on its website. (The Guardian is the second biggest newspaper site in the world) I thought I would reach out to you to ask for what are your favourite math puzzles. Any suggestions? I think a good math puzzle for a newspaper is one that is easy to state and tricky to solve, or at least that requires lateral thinking, but not too tricky and definitely not technical as the readership will largely be non-mathematicians. Maybe some of you have your own puzzles, or twists on classic puzzles, you might want to share. My hope is that the Guardian’s puzzle page becomes a reference in puzzle-land for the dissemination and discussion of mathematical conundrums, posers, brainteasers and the like... Please share on the list, or email me direct… Thankyou! Alex
