Water Sort Puzzle

Tap on a glass to select it, then press on another glass to transfer the water. Only pour water if the top color of the first glass is the same as the top color of the second glass or if the target glass is empty. Sort the colored water so that each glass contains only one color. Complete all the glasses to progress to the next level. Use tactics to stop getting stuck with unmovable colors. Note that some levels may require multiple steps to solve.
