1. With the printed artwork on the outside, fold each corner support along the center to create a 90° angle.
2. Empty the game box and flip the box bottom (the Excavation Site) upside down.
3. With the support flanges pointing up, tuck a corner of the box bottom over both bottom flanges. (The box corner should be tucked into the inside of the 90° angle of the support.)
4. Repeat for each of the 3 other corners.
5. Finally, do the same with the top flanges and the box top (the Temple Floor).
