We’ve created a puzzle that will keep you guessing for hours, days, weeks, and even months. The Gold is a complex maze with 15625 possible variations, inspired by a lock. Each puzzle’s combination necessitates the development of an algorithm based on a number of clues. Owing to the high manufacturing costs associated with the numerous materials, we are no longer able to manufacture the Gold.
