GRECIAN TRICK LOCK - For over 6000 years, humans have used some form of lock to secure their goods from would-be thieves and malcontents. The most common lock is the padlock or ‘Warded Lock’ and is credited to famed Greek Inventor and sculptor Theodorus of Samos who is known for his work in bronze casting and development of tools such as the lathe, the key, the level and more. It is said that Theodorus invented a lock so challenging, not even the most skilled thieves of the time could crack it. Unfortunately, the designs for that lock have been lost to antiquity, until now. THE GOAL of the Grecian Trick Lock is to open the lock using the tools provided. It looks simple, but it is not as simple as it may seem. Difficulty level is 3 stars.
