"At the end of the 19th century, Britain experienced a huge puzzle craze. I managed to pick up a number of the puzzles famous during that period in flea markets, despite their rarity. Based on these original puzzles from Britain’s famous puzzle period, this is one that we have successfully revived in its new form. The key point of this puzzle is decisively navigating its labyrinth, in which exists one point of weakness for you to break through. For the indecisive part of you."
