Happy Glass and the drawn path that fills the cup
Happy Glass mixes a smart Puzzle setup with water flow and gravity, so every stage asks you to guide a stream into an empty glass. You sketch with a magic pencil, then watch whether your line actually catches the drops and gets the cup to the dotted mark.
Draw with a limited ink trail
The main challenge comes from the ink meter, because every stroke costs you part of your drawing budget. That pushes you to build short ramps, funnels, or shields instead of covering the screen, which makes each move a small planning problem.
On desktop you drag with the left mouse button, while touch controls let you draw directly on the screen, so it plays cleanly in the browser with no download and no signup. Simple shapes matter most when you need to support a falling stream without wasting ink.
Obstacles that break the water
Later stages add hot platforms, spinning pieces, and spikes, and each one changes how you route the flow. That is where the game starts feeling like a real physics challenge, because the same line can save the glass or let the water slip away.
Using fixed blocks as anchors helps your path stay in place, especially when you need a wall, slope, or tiny bridge to steer the drops. If you like drawing-heavy puzzles such as DOP: Draw One Part, this one gives you a different reason to sketch.
Stars, retries, and browser play
Your result depends on how much ink you spend, so cleaner solutions earn better stars than messy ones. That scoring system keeps the focus on efficient lines, and it works smoothly in modern browsers on phones, tablets, and computers.
