Popo Marble | Maru

Popo Marble (Maru) is a simple, addictive marble-puzzle Chrome extension that trains logic and spatial reasoning. The goal is to push all marbles off the screen by touching a marble, dragging it, and striking others so they’re sent out of bounds. Each move must be planned so one marble can push the next — the deeper you play, the more strategic thinking required.

Designed for quick sessions and progressive challenge, Popo Marble combines tactile drag controls with puzzle strategy to boost brain development and reflexes. Perfect for casual play, kids, and anyone wanting a compact brain-training game. Install the extension to start relaxing and sharpening your mind with intuitive marble physics and escalating puzzles.
