If you want to have a great activity to do where you solve puzzles and work together - this is really a lot of fun. We started out planning to do it within an hour - two adults and 3 teens. We chose expert level because we think we are really smart. 3 hours later we solved it. You can definitely do this in under an hour because there are hints all along the way so you don’t have to ever stay stuck. This was such fun. We can’t wait for our next crate!!!
