About Happy Glass
Happy Glass is a free physics puzzle game in which you draw lines on the screen to guide a stream of liquid into an empty glass. The lines you draw become solid objects that fall and interact with the scene, so filling the glass is as much about where your ink lands as where the water flows.
Each level gives you a fixed amount of ink and a glass that must be filled past a marked line to pass. The clever part is that your drawing is not a static wall — it is a physical object with weight, so a line drawn across a gap will sag, tip, or knock over the very glass you are trying to fill. Levels frequently involve drawing something small to wedge a moving part in place rather than building a ramp at all.
The three-star rating rewards economy. Passing a level usually only takes a rough funnel, but earning all three stars means solving it with the minimum ink, which often reveals a much simpler intended solution — a single short stroke that redirects the stream instead of the elaborate slide most players draw first.
How to play Happy Glass
Tap and drag to draw a line anywhere on the screen. Your drawing becomes a solid object that gravity acts on. Use it to catch the falling liquid and channel it into the glass. Fill the glass past the marked line to complete the level; you can erase and redraw as often as you like before the water runs out.
Tips and strategy
- Draw short strokes, not long ramps. A long line sags under its own weight and usually collapses before the water reaches the glass.
- Look for the object that needs blocking rather than the path that needs building — many levels are solved by wedging a moving part still.
- Anchor lines against existing scenery at both ends. A line touching solid geometry holds; a line floating in space tips over.
- For three stars, solve the level again with the shortest possible stroke. The ink-efficient solution is usually completely different from the obvious one.

How do you get three stars in Happy Glass?
Three stars are awarded for using the least ink, not for finishing fastest. The efficient solution is usually a single short stroke that redirects the stream, rather than the long ramp most players draw on their first attempt.
Do the lines you draw in Happy Glass have weight?
Yes. Anything you draw becomes a solid physical object affected by gravity, so long unsupported lines sag and fall. Anchoring both ends of a stroke against existing scenery is what keeps it in place.
