This activity is a must!!! We are vacationing in Poland and found this activity on Trip Advisor. We called and made a reservation same day and did the easiest scenario which is super tricky but loads of fun. There were 6 stations and as you solve the puzzles you progress to the next puzzle, after solving the 6 puzzles, you have to solve the cube puzzle in the center of the room; by solving the large cube which is the final puzzle: the door opens and you can leave - YOU WIN!
