Water Sort Puzzle

Tap on a glass to pick it, then tap on another glass to transfer the water. You can only pour water if the top color of the first glass matches the surface color of the second glass or if the second glass is vacant. Sort the colored water so that each glass contains only a single color. Complete all the glasses to advance to the next level. Use tactics to avoid getting stuck with unmovable colors. Keep in mind that some levels may demand several moves to complete.
