A free puzzle game where you pour colored water between tubes until each tube holds one color.
Best for: Anyone who wants a relaxed free puzzle game for short breaks.
What we like
- Easy rules that anyone can learn in a minute
- Free to download and rated Everyone
- Short levels suit quick sessions
- Can be played one-handed
Watch out for
- Has ads between levels
- Includes in-app purchases
- Later levels can feel repetitive
Each level gives you a set of tubes filled with mixed layers of colored water. You tap a tube, then tap another to pour, but you can only pour onto the same color or into an empty tube.
The early levels are simple, and difficulty grows with more colors and fewer empty tubes. If you get stuck, you can usually undo moves or add a tube, and some of these helps may need ads or purchases.
It is free, so expect ads. It suits players who want something calm and low-pressure to fill a few minutes.
