We did Moriarty's Manor with a group of 5 and we found it pretty challenging! My group had varied experience levels (a few beginners, a few with 10+, and one who had done 30+) and we still had to request around 5 hints (and finished with only 5 minutes remaining). The puzzles had really cool tech with a lot of new things that I had never seen before. We really beat ourselves up on things that we requested hints for because we should have got it in the first place. All of the puzzles were logical and cohesive. Our GM Victoria was a sweetheart and we're definitely looking forward to coming back to play the black and white cafe room as well. This has probably been my favorite room in San Diego due to the really cool puzzle tech and high difficulty. Would recommend playing this with at least 3 people even though the min is 2.
