Join the puzzle in progress in the center of the Main Library, and you'll find that you're now a Puzzler!
This is a very informal, always changing, group. No formal meeting or time to gather, just people who enjoy puzzles! Work on the current puzzle at your leisure, visit with others if you want, and set your own schedule. Be prepared for the puzzle to change but there's usually more than one going at a time, so you should have a chance to see the finished creation.
Check in with the Reference Desk if you have any questions.
