Colored Test Tubes is a game where you solve puzzles by pouring liquids. Your task is to sort the colored liquids so that each color ends up in its own test tube. The levels become more challenging as you advance, with more colors and fewer empty tubes available. You have the option to reverse your last move or start the level anew. If you find yourself stuck, you can use a hint or perform a special «rainbow move» after watching an ad. The game runs well on both mobile devices and computers.
How to play
To choose a test tube, tap on it. Then tap another test tube to pour the liquid. You can pour it either into an empty tube or one with the same colour. Your goal is to fill each test tube with a single colour to finish the level. Use «Back» to undo your last move. «Restart» will let you begin the level again. «Hint · Ad» gives you a move suggestion after watching a video. With «Rainbow Move · Ad», you can mix any colours for a short while after viewing an ad.
