About This Game

Water Flow Happy Glass is a physics drawing puzzle: an empty glass waits under a faucet, and your pencil is the only tool — draw any shapes to direct the falling water into the glass, filled up to its target line. Five unique worlds vary the physics playground: a classic lab, fiery lava realms, magical worlds, with teleports, ice blocks and bouncy platforms complicating the pours. The star system rewards minimal ink — fewer lines drawn, more stars earned — which converts drawing from freeform doodling into economical engineering. Daily challenges keep the supply fresh. It is the rare physics game that teaches actual spatial cause-and-effect while feeling like doodling. Free to play online, no download.

How to Play

Click and drag on the screen to draw lines or shapes, guiding the faucet water unobstructed into the glass — it must fill up to the target line. Save ink: the fewer lines you draw, the more stars you earn. Work through the 5 worlds of teleports, ice blocks and bouncy platforms, and try the daily challenges.
