“Small joys are bringing us together now more than ever and puzzles are a big one,” the company says on their website. “So big that puzzle companies can’t keep up! Unless people start mixing different puzzles together (not recommended), everyone needs new-to-them puzzles. Thankfully, we have the know-how to help find new homes for puzzles everywhere. We hope you’ll help us pass on the fun and do some good, too.”

According to ThredUP, more than 2,000 people signed up to participate in the swap in the first week, and their numbers have continued to climb since.

And while the program is meant to be all fun and games, they do have one serious rule: “Only send complete puzzles please!” they write. “Puzzle Karma is a thing.” Make sure the puzzles are in their original box, too! 

Visit thredUP.com/puzzles for more details and to sign up, and peruse thredUP.com/puzzles/shop to see all the puzzles currently available for purchase.
