Ball Sort 2D

Ball Sort 2D is a straightforward browser puzzle where you organize colorful balls into specific glass tubes until each container holds a single shade. The game stands out because you can only move a sphere onto another one of the exact same color or into an empty slot, forcing you to plan moves ahead rather than just swapping randomly. It focuses entirely on this color-sorting mechanic without adding timers or complex distractions.

You tap on a bottle to pick up the top ball and tap again to drop it into the destination tube. Every turn, you must decide whether to clear a specific shade completely or use empty bottles as temporary holding slots for balls that block your progress. The rules limit moves to valid stacks, so you cannot place a red ball on top of a blue one, which keeps the logic tight. You simply keep tapping until every tube is uniform in color.

Casual players looking for a quick mental break will enjoy this because it requires zero setup and has no fail state beyond getting stuck. Tip: In the first minute of play, identify the tubes that are already nearly full and focus on emptying those completely to free up space for the mixed ones.
