The original Lockbox Adventure!
This locked box is sealed with a 4-digit combination lock. You will not be given the combination, but instead a series of puzzles, each one (when correctly solved) will yield a digit to the combination. Solve them all correctly to learn the combination and claim what's yours! Solve them without clues (#lbaNoHelpNeeded) or without giving up (#lbaNeverGiveUp) for extra kudos.
This box has a retail value of over $60 and takes players, on average, about 5 hours to complete.
