About Happy Glass
Happy Glass is a drawing puzzle about filling a sad glass with water until it smiles. Water pours from a tap somewhere on the screen; you draw lines with the mouse and those lines become physical objects that the water runs down, pools behind, or knocks over. Get enough water into the glass and the level is done.
The trick is that your ink is limited. A three-star solution is usually a single well-placed short line rather than a long elaborate chute, which turns each level into a small optimisation problem rather than a scribble.

Happy Glass tips
- Draw short. The star rating is based on ink used, and most levels have a one-stroke solution.
- Lines can knock things over and be knocked over themselves — use gravity rather than fighting it.
- A slight angle beats a steep one; water accelerating down a steep ramp overshoots the glass.
- If water is splashing out, aim to hit the inside wall of the glass rather than its centre.
Happy Glass — questions
How do you get three stars in Happy Glass?
Use as little ink as possible. The rating is based on how much you draw, so a single short well-placed line beats a long chute that also works.
What happens to the lines you draw?
They become real physical objects — they have weight, they can tip over, and things can fall on them. That's part of most puzzles.
Does Happy Glass work on a phone?
Yes — draw with your finger. It runs in the browser with nothing to install.
