Color Drain

Open valves to drain layered liquid tanks in a candy-colored lab. Each valve empties only the bottom layer, so plan your order to match the color list without hitting a dead end.

Color Drain is a sequencing puzzle set in a bright lavender laboratory. A row of glass tanks holds stacked layers of colored liquid, and an order bar at the top lists the colors you must drain, one after another. Tap a tank to open its valve and the bottom layer gurgles out through the chrome pipes into a collector. It only works if that bottom color is the one the order asks for next.

The tricky part is planning. When two tanks have the right color at the bottom, picking the wrong one can leave you stuck later, with no tank able to supply the next requested color. A dead end costs a life and refills the board with a fresh set, and so does tapping a tank whose bottom color does not match. Every order is generated by simulating real drains, so each level always has a solution. Levels grow from three tanks with two layers up to six tanks with five layers and six colors, and you earn points for every drained layer plus a speed bonus for clearing a level quickly.

This color logic game suits players who enjoy thinking a few steps ahead at a relaxed pace. Tip: before draining, look at the next few colors in the order bar and check which tanks reveal them underneath.

How to play

Tap a tank or press its number to drain its bottom layer. The color must match the next color on the order bar. Plan which tank to use when several match, because a dead end where no tank can supply the next color costs a life and refills the board. Tapping a tank with the wrong bottom color also costs a life. Each drained layer scores points and fast clears earn a bonus; the run ends when all three lives are gone.
