Column Clean

This soothing color classification puzzle game can help you calm down and relieve daily stress! It has a soft color visual effect, smooth animation, and a slow and gentle game rhythm that brings calmness and focus.
All you need to do is sort the stacked colored balls into transparent small bottles. Systematically rearrange the cluttered layers to give each small bottle a clean color. The intuitive rule system makes the game easy: only the top ball can move, and effective placement is limited to empty bottles or matching colored balls. The orderly sorting process creates a strong sense of cleanliness and comfort.
