Super Mario

Do you recall Super Mario? First off, head to this site and print out a few of these box designs.

I like using thick card stock because it holds up better. Next, stuff them all with cotton, leaving just one open so you can place your key right in the middle before sealing that one too. Shuffle everything around until they look identical and spread them out across different rooms. Once you’re tied up, you’ll need to check each box for the key. Enjoy yourself.
