I love logic puzzles. I can get lost in them for a couple of hours, and I’m NOT a math person. You can ask anyone who knows me. I would never have known they existed had it not been for the interview I was preparing for many years ago. I used them to prepare for a math test that was part of the interview process, and I’ve been doing them ever since. It’s the logic puzzle with grid type that I gravitate toward, and when I find a book of them I buy it immediately and look for pockets of time to squeeze in puzzle-solving. The easy ones are useless because they are too easy, and the hard ones are useless because they are meant for the math people. So, I hang out in the medium difficulty section and go to town.
