Happy Filled Glass

Draw a line, guide the water, and fill that grinning glass to the top — just don't waste a single precious drop.

Happy Filled Glass is one of those games that looks too simple to be interesting, then you're three levels deep at 1 a.m. trying to draw a tiny ramp under a leaky faucet. The goal never changes: get water into the glass. But the solutions are puzzles hiding in plain sight. You draw lines anywhere on the screen, the water pours, and the lines act like solid walls. Some levels give you a single glass to fill, others split the stream or hide the glass behind blocks. What got me first was the physics. Water has weight, it pools, it splashes a little. Your ink is limited, so you can't just draw a giant funnel every time. I remember one level where the glass sat under a shelf and all I had to do was tilt the floor — but I spent five minutes building a ridiculous contraption before noticing the obvious answer. That's the charm: the game rewards both clever designs and cheap tricks. You can erase lines and redraw as long as you have ink left, so there's no penalty for tinkering. The visuals are cheerful, the music is calm, and the levels ramp up gently. It works great with a mouse or a finger, so it's perfect for a quick break. If you like physics puzzles that don't punish you for experimenting, this one's a keeper.

Use mouse or touch the screen!

Sketch lightly — you can erase and redraw as long as you have ink left, so test small changes before committing. Use gravity to your advantage: a slight slope often works better than a full enclosure. Watch where the water actually lands, not where you think it will — the physics can surprise you. Don't waste ink on unused lines; every drop counts when you have multiple glasses to fill. Sometimes the simplest straight line beats a fancy curve. If water is pooling in the wrong spot, delete part of your line and let it flow naturally.
