Bubble Sorting Game

Bubble Sorting is a relaxing but deceptively challenging puzzle game that tests your logic and spatial reasoning. You are presented with several test tubes, each containing a mixed stack of colored bubbles. Your goal is to sort the bubbles so that every tube contains only bubbles of a single color, or is completely empty.

The rules are simple: you can only move the top bubble from a tube, and it can only be placed into an empty tube or on top of a bubble of the exact same color. As you progress, the number of tubes and colors increases, requiring careful planning to avoid getting stuck without any valid moves. It is the perfect browser game for a quick mental workout or a relaxing session of sorting.

Controls

• Left Click / Tap: Select a tube to pick up its top bubble, then click another tube to drop it.

Tips

• Empty tubes are key: Focus on clearing a tube completely as early as possible. An empty space gives you the flexibility to shuffle bubbles around.
• Think two steps ahead: Before moving a bubble, look at what color is underneath it and plan where that next bubble will go.
• Don't rush: There is usually no time limit. Take a moment to analyze the board before committing to a sequence of moves.
