There are four levels. There are four different placements of zodiac signs on each side. You can change it using the "Sort" button. On the first page, rearrange the zodiac signs by moving the three zodiac images to the open spaces. The second side has six zodiac signs. The third side has nine zodiac signs. The fourth side rearranges all 12 zodiac signs. There are no open squares after the second side. When you press the arrow button, the zodiac image closest to the arrow side will move to the opposite side of that column, and the others will move one by one to the arrow side. You need to rearrange not only the zodiac image you want to move, but also the movement of other zodiac images. Please try and see how you can reduce the number of rearrangements. If the sorting is not completed, click the "Solve" button to check.
It is a brain training to rearrange the random zodiac signs in order from the upper left to the lower right.
