This page has the rules and printoff necessary to play Cache Me If You Can (by DPH Games) in a cooperative variation (or potentially solitaire) called “Muggles!”. We played it at TimeSeeker’s house. He’s the one who came up with these variations. We recorded ourselves the second time so you could see the game play in action. He created this for version 2, but it could be easily modified to work for version 3. I apologize in advance for my son being absolutely bonkers.
