Happy Filled Glass Game

You've got a glass, a stream of water, and a blank space between them—can you sketch a route that gets every drop inside?

I'm not usually one for 'relaxing' puzzle games, but Happy Filled Glass hooked me on the first level. You get a limited amount of ink to draw lines and shapes anywhere on the screen, then hit play. Water pours from a spout, hits your scribbles, and—if you've planned it right—slides straight into the waiting glass. The satisfaction when the water level hits the target line is real. Miss, and you watch the water splash uselessly onto the floor while the glass sits there, mocking you. What makes it work is how physical everything feels. Water doesn't just follow your line; it pools, drips, and spills in ways that make sense. Sometimes you need to draw a funnel to catch a wide spray, other times a ramp to redirect a trickle around a barrier, and occasionally you'll need to nudge the glass itself by dropping a drawn weight onto a lever. Later levels add moving platforms, multiple streams, and glasses that roll away if you're not careful. I spent way too long on one stage where the only solution was a tiny drawn wedge that tilted the glass at the perfect angle. Controls are dead simple—mouse or tap to draw, an eraser if you mess up, and a limited ink bar that forces you to be economical. That limitation is the real puzzle: you can't just build an elaborate marble run. You have to use the least ink possible while accounting for splashes and momentum. It's the kind of game you'll pick up for five minutes and then realize an hour vanished. Not bad for something that's basically digital plumbing.

Mouse or tap to play.

Use the ink meter as a puzzle hint: if a solution needs more than one full bar, you're overcomplicating it. Draw shallow ramps instead of steep cliffs—water loses speed on sharp drops and can overshoot the glass. Test the first second of flow before committing: pause and erase if the stream barely misses the lip. Watch for movable objects like balls or blocks; a drawn barrier can nudge them into position. In levels with multiple glasses, fill the lowest one first; water will naturally flow downhill. Don't forget you can draw inside the glass to create a funnel if the stream comes in too fast.
