SET of 3 brain games, 1 escape book

Up for grabs are 3 brain games and 1 escape book. The listed price is for all of the 4 books. In the pictures, please read each book's description. I did about 20 puzzles in the Code Breakers book. The others should be untouched. Other than what's noted, there should be nothing wrong with any of the books. I purchased these, and I haven't had the time to work on them... so it's time to pass them on... Any questions, please reach out to me prior to purchase. I will answer as quickly as possible. I work a full-time job and work 12 hour rotating shifts. Thank you for looking and for understanding!
