What a great rainy summer day family activity! 90 minutes around the table solving puzzles was very rewarding. The Carnival of Chaos was just the right level and our Deadbolt Mystery contact Crystal knew it! The box had everything we needed to dig in and discover the mastermind. My seventh grader solved whodunnit, he is so proud! I recommend these Deadbolt Mystery Society boxes to all, bxes would also make great team building activities!
