Enjoyable game with satisfying solves. I really liked this concept, forcing players to communicate. There is no room, all the puzzles are built into a small wall. The objective of the puzzles were to open padlocks (no tech) but they still managed to make it a tactile experience with many objects to manipulate. The puzzles were the right amount of difficulty for us, not too hard or easy. There is a bit of math in this one, but it's basic arithmetic you can do in your head. My team of 3 did need 1 hint (but it was something we should've been able to figure out), the hints were written on cards, there is no GM watching you. My only wish is that they had a progressive hint system giving you smaller bits of information instead of walking you through the entire puzzle at once.
Make sure your strongest puzzler is on the correct side, they should tell you which one they should be on when you start.
I played this and Wayward Spacers at Gen Con and enjoyed them both similarly, though Wayward Spacers is more difficult.
