A little glass is waiting with a sad face, and the only way to cheer it up is to fill it with water. Water pours from a tap when you finish drawing, so your job is to sketch ramps, walls and funnels that guide every drop into the glass. Each level has a new layout, and there is rarely only one correct answer.

📘 Happy Glass: drawing puzzle solutions and tips
Happy Glass is a creative physics puzzle: draw one or more lines so the water pouring from a tap ends up in the glass. It is popular with all ages because there is no single correct answer — any drawing that works is a good solution.
Think like an engineer. A slightly tilted line works as a ramp, a cup shape catches water and a wall stops it from escaping. Because water starts flowing as soon as you finish drawing, it helps to imagine the path of the water before you touch the screen.
The game uses limited ink in many levels, so shorter, smarter lines earn more stars. That constraint encourages kids to find efficient solutions.
Pro tips for Happy Glass : Fill the Glass by Draw Lines
- Draw ramps at a gentle angle so the water doesn't bounce out.
- Close the gaps around the glass with small walls.
- Use less ink for more stars.
- If a level seems impossible, try drawing above the glass instead of below.
