Liquid Color Sort

Liquid Color Sort is a puzzle video game released for mobile platforms, including iOS and Android. The game presents a series of levels, each containing a set of glass tubes or flasks. These tubes are partially filled with layers of colored liquid. The objective of each level is to separate the mixed colors into individual tubes, so that each tube contains only a single, uniform color. The game employs a physics-based simulation where the liquid behaves with realistic fluid dynamics, including surface tension and pouring animations. The difficulty increases progressively as more colors and tubes are introduced, requiring strategic planning to avoid deadlock states. The game features a minimalist visual design with a clean interface, no timers, and no penalties for incorrect moves, allowing players to undo actions or restart levels freely. It is categorized as a logic puzzle game, often compared to sorting and matching genres.

Gameplay and controls are based on a single touch or click interaction. The player selects a tube by tapping on it. This action lifts the topmost layer of colored liquid from that tube. The player then taps a second tube to pour the held liquid into it. The pour is only permitted if the target tube is not full and either contains the same color at its top layer or is completely empty. The liquid is transferred in a single continuous layer, not in individual units. The game provides an undo button to reverse the last move. A restart button resets the current level to its initial state. Additional tubes, often empty, are provided as temporary holding spaces to facilitate the sorting process. The interface displays the current level number and a move counter. No other controls, such as rotation or zoom, are present. The game ends when all tubes contain a single color, at which point the level is completed and the next level is unlocked.
