Decoding the cipher presented by the four magnetic triangular tiles and the inlaid top/four sides of this box is the key to opening the box. Placing the four tiles correctly on the top (they are not so placed in the photo ... or are they?) will provide a clue as to how subsets of these tiles should be placed on the sides of the box. Correctly placing the tiles on the sides will unlock the associated panels and, ultimately, a compartment will be revealed. A minimum of 13 moves is required. This is perhaps my second favorite Yarger creation ... kind of a "magic tile lockbox on steroids."
