A physics puzzle solved by drawing. Water falls from a fixed point, an empty glass sits somewhere it cannot reach, and you draw a line — which becomes a solid surface — to guide the water where it needs to go. The glass has to fill to a marked level, and the ink you have is limited. That ink limit is what turns it from a doodling exercise into a puzzle. A generous funnel solves most levels and scores badly; the good solution is usually a single short stroke placed exactly where the water changes direction anyway, and finding it is genuinely satisfying. Hundreds of levels escalate by adding moving parts and obstacles, and because the physics are consistent a failed attempt shows you precisely where the water went wrong. It is one of the cleanest ideas in the mobile puzzle canon.

How to play Happy Glass
- Watch one attempt without drawing to see where the water naturally goes.
- Draw short strokes at the point where the water needs to change direction.
- Use the level's own geometry; the walls and edges do work you do not need ink for.
- Aim for the glass's near edge rather than its centre, since water spreads on impact.
- Restart freely — ink efficiency is what the stars measure.
Tips
- A single well-placed stroke beats a funnel every time, both for score and reliability.
- Water pours rather than falling in a line, so a narrow channel loses some of it.
- If a level seems to need a lot of ink, you are probably drawing in the wrong place.
Questions about Happy Glass
What do I draw with?
A limited amount of ink, which becomes solid lines.
What is the goal?
Filling the glass to a marked level.
Does ink use matter?
Yes, it is what the level rating measures.
How many levels are there?
Hundreds, escalating with moving parts.
Does it work on a phone?
Yes, drawing with a finger is natural.
Does it need installing?
No, it runs in the browser.
Is the physics consistent?
Yes, which makes failures informative.
