The sorting puzzle Donut Puzzle Sort Diamond Art asks you to restore pictures collected from multi-colored donuts at each level. They act as a diamond mosaic. Initially, the colors on the pattern do not match the donuts placed on them. Below the pattern there is a row of cells where you can temporarily move some of the donuts to free up space in the picture and move donuts of the corresponding color there. Then you can pick up the previously moved elements from the spare panel and place them on a sector of the same color. When all the donuts are sorted by color, the pattern will be restored and you can move on to the next level in Donut Puzzle Sort Diamond Art.
