A Mathematician at Play Puzzle #1

I’ve been collaborating with the English-language newspaper in India called The Hindu for the past few months, producing puzzles for a column called A Mathematician at Play.

It’s a great collaboration. I produce the puzzles, and they make them look beautiful.

I’m going to start sharing these puzzles on the Math for Love blog. Some of these puzzles are classics, others are original. All of them involve some kind of thinking or insight that strikes me as pretty, or surprising, or delightful.

Puzzles will go out Mondays for the next few months.
Answers will go out Fridays.

The first puzzle, below, is a series of grid puzzles. I hope you have fun trying these out! Share them with your kids or students, or work on them with your friends, and let me know what you think in the comments!
