Happy Glass is a simple yet cleverly designed hyper casual puzzle game where your goal is to bring a smile back to an empty glass. By drawing lines directly on the screen, you create paths that guide flowing water from the tap into the glass. Each stroke becomes a physical object, so every line you draw affects how the water moves, making timing, placement, and shape all matter.

Set against a clean, grid-style background, each level presents new layouts with platforms, gaps, and tricky angles that challenge your creativity. You’ll need to think ahead and use as little ink as possible to achieve a high completion rating and earn up to three stars. As the stages progress, obstacles become more complex, encouraging experimentation and smart problem-solving.

With intuitive controls and quick, satisfying levels, Happy Glass offers a relaxing yet brain-teasing experience. Whether you carefully craft precise ramps or improvise bold solutions, the joy comes from watching the water flow perfectly into the glass—and seeing that once-sad face turn happy again.
