Water Sort Puzzle

Click on a glass to choose it, then tap on another glass to pour the water. You can only pour water if the top color of the selected glass is the same as the surface color of the target glass or if the second glass is empty. Arrange the colored water so that each glass contains only a single color. Complete all the glasses to progress to the next level. Apply strategy to stop getting stuck with unmovable colors. Remember that some levels may demand several attempts to finish.
