The basics

How to play Color Drain:
drag the nozzle, drain every drop.

You play Color Drain with one finger. Press and hold anywhere on a painted surface and drag: the nozzle vacuums the color away and the low-poly city underneath comes back. Clear the whole surface before the timer runs out.

200 levels across 20 chapters in two worlds — all built, with a three-phase boss at level 100 and a second boss at level 200. Levels 1–4 are an untimed tutorial; from there, drain faster to earn 1–3 stars based on time remaining. If the timer runs out, watch a short rewarded ad for +15 seconds — or accept the fail and retry.

Free to play, with ads (rewarded videos you choose to watch and an ad between some levels) and optional in-app purchases. Built with Unity by RDD-Labs — a two-person mobile game studio in Ashdod, Israel, obsessed with polish and feel.

2
Drag the Nozzle Control a suction nozzle with your finger. Drag it across painted surfaces to vacuum up every drop of color.
3

Level Progression

200 levels. 20 chapters.
Two worlds, two bosses.

The difficulty climbs naturally — new surface types, tighter geometry, bigger dioramas — all the way to The Siphon, Baron Blank’s three-phase boss at level 100, at the end of Rainbow City. Then the Golden Dunes bring a new kind of Blot, the Ripple, and end with Viscountess Drab at level 200. The plan is a boss every 100 levels, on the road to a giant boss at level 1000.

Chapters 1–2 of 20 shown below. One of our closed testers reached level 100 before launch.
