Drainworks: Valve Sort Puzzle

Every tube has a bottom valve — drain buried colors from underneath.

Sort the colors into their tubes — but this waterworks has a secret under the floor.

Every tube in Drainworks has a valve at the bottom. When the color you need is buried under three others, don't dig it out — open the valve and drain it straight from underneath. It flows through the pipes and slides into the next tube from below. Suddenly, order doesn't work like it used to.

50 hand-checked levels take you from calm pouring to sealed mouths, rusted valves, and hidden liquid. Every level is guaranteed solvable, with a fair par: beat it for 3 stars, and watch your stars literally drain away when you waste moves.

Relaxing to play, tricky to master, and every puzzle can be cracked — sometimes you just have to think from the bottom up.
