This one had A LOT of puzzles which we LOVED. Our core group was 6, and I think that was perfect range (6-8). Any more and it just gets crowded. We had three other people with us as it was a “shared experience” which is definitely not our fave, but they were nice to work with. They recommend up to 12 for the room, but that’s WAY too much. The concept was novel and just challenging enough. We used 2 hints and got a nudge, but overall was really fun.
