All kinds really.
I’m currently working on my first jigsaw puzzle in almost 9 years. Just before we started having kids. Go figure.
I’ve also been blazing through my wife’s PennyPress puzzle book, and I tend to reduce many games like Backgammon and Cribbage to pattern puzzles.
My job is also a continual search for patterns and matching similar patterns to a common source.
I love puzzles. Don’t you?
