Happy Glass Draw a path for the water and fill the glass with as little ink as possible.
Sketch lines that guide falling water into the glass, complete relaxed physics levels, and chase three stars by solving each layout with fewer drawn strokes.

The Happy Glass idea
Turn one line into the perfect water path
Happy Glass is a drawing-based water-physics puzzle. Sketch a line that becomes a physical ramp or barrier, release the water, and guide enough of it into the marked glass to make the character happy.
Clearing a level is forgiving, while earning three stars rewards shorter and more efficient lines. Classic mode includes 688 levels, and the menu also offers Don't Spill, Flippy Glass, Precise, challenges, minigames, a lucky wheel, and cosmetic categories.
Passing and optimizing are separate goals
A long line may safely fill the glass, but a shorter solution preserves more of the star meter.

Drawing and water physics
Draw a path that fills the glass
Inspect the water source. Locate the falling water, the glass opening, and any fixed platforms that can support a drawn line.
Draw a guide. Drag to sketch a ramp, wall, or bridge that redirects the water toward the glass.
Watch the water physics. Let the stream follow the drawn shape and adjust if too much water spills away.
Refine for three stars. Replay with less ink or a cleaner angle when you want the full three-star result.

Happy Glass guide
Pass first, then shorten the line
Start with the shortest stable shape you can imagine. The line must catch the water without rolling or falling away, but every unnecessary stroke reduces the three-star efficiency result.
Use fixed objects as anchors
Attach a short line to existing platforms so the physics holds it in place when the water begins to flow.
Guide the center of the stream
Aim the line under the main water path instead of trying to catch every stray drop.
Pass first, optimize second
Use a safe solution to learn the physics, then replay with a shorter stroke when pursuing three stars.
Questions
Happy Glass FAQ
How do I make the glass happy?
Draw a physical line that guides enough falling water into the glass to reach its fill requirement.
How are three stars earned?
Use less drawing ink and a more efficient solution while still filling the glass.
How much content is there?
Classic mode includes 688 levels, plus unlockable modes, challenges, minigames, a lucky wheel, and cosmetic categories.
Can I play Happy Glass in a browser?
Yes. Happy Glass runs in the embedded browser player on this page without a separate download.
Ready to fill another glass?
Return to the drawing board and sketch a shorter path that still catches the stream.
