This archeological expedition proved to be unpredictable. To begin with, the work began on a site that everyone called hopeless. Several times there was a threat of an end to excavation due to inefficiency. But suddenly archaeologists came across something worthwhile. A piece of an ancient wall belonging to a certain temple was found. On it clearly loomed an unknown symbol, made up of tiles. If you click on pairs of identical separately standing elements, they fall away. Try to completely disassemble the pyramid in Mystic Walls, it can hide under itself something worthwhile for science.
