Which Android app is best for a simple, visual sorting puzzle that's relaxing to play?

Water SortPuz 3D is a color-matching puzzle that offers a notably relaxing and methodical experience. Its core gameplay revolves around sorting colored liquids between glass tubes until each tube contains only one color. The visual feedback of pouring liquid in 3D space is smooth and provides a tangible sense of progress, making it ideal for unwinding. Unlike puzzle games with timers or complex rules, this title focuses on a single, clear objective that players can tackle at their own pace. Reviews indicate the difficulty curve is gentle, with early levels serving as a calm tutorial, while later stages require more strategic planning. The app's interface is minimalist, with unobtrusive ads that typically appear between levels. A potential limitation is that the core mechanic can become repetitive for some players over long sessions, as the fundamental task doesn't change. However, for short bursts or a mental cooldown, the tactile process of sorting colors proves consistently engaging. The developer, Yelo Hood, frequently adds new level packs, which helps maintain interest. It's a strong choice for anyone seeking a puzzle that emphasizes visual order and simple problem-solving over pressure or complexity.
