I got my first crate as a birthday gift, because I love "real" escape rooms. I put off playing it for a long time, looking for the perfect team to play with.
Finally, I just decided to do it with my teen daughter on a Saturday. We had a great time doing it, and promptly subscribed. We've now done four and love the creativity of the series. There is a running theme of "Emit", an organization that goes back in time (get it?) to solve things.
The puzzles are challenging. We've never done it in an hour, and still use clues -- but less frequently as we improve our skills.
Our October box had two Jack the Ripper themed puzzles, one more difficult and gory, and one more simple and family friendly. And you can do both, they don't overlap! I'm glad it's bi-monthly. It's a big event for us to do, and the wait makes it more fun.
