Gold Aztec

In the game “Aztec Gold” you are required to collect the “keys” to the entrances behind which lie numerous treasures.
Rules of the game: On the gaming field is a stone entrance, composed of 16 blocks. On these blocks are variously colored crystals and rings. The quantity of crystals of each hue is consistently equal to the number of rings of the identical color. You must arrange the crystals so that they align with the shade of the corresponding ring.
To shift the crystals, click the screen in the central area of the four blocks. In this instance, the four crystals situated on these blocks will instantly rotate clockwise to the subsequent position. Continue this process until all 16 colored crystals are positioned within the rings of the matching color. Ponder each move carefully. Attempt to unlock the entrance with the fewest possible moves, as this will determine how many treasures you will uncover.
