Water Sort Puzzle

Click on a glass to pick it, then tap on another glass to move the water. You can only pour water if the surface color of the selected glass matches the surface color of the second glass or if the second glass is vacant. Organize the colored water so that each glass contains only one color. Solve all the glasses to advance to the next level. Employ strategy to avoid getting stuck with untransferable colors. Note that some levels may demand several attempts to solve.
