Happy Glass — Play Free Online

Happy Glass is a physics puzzle about water and a very sad glass. A stream of liquid pours from somewhere above, the glass sits somewhere below, and nothing connects the two. Your job is to draw a line that catches the water and steers it into the glass, which cheers up once enough has landed in it.

It is a different kind of challenge from the two-player temples this site is known for. There are no switches, doors or elemental hazards, and nobody to coordinate with. Each level is a small drawing problem you can read at a glance, and a try takes only a few seconds, which makes it a good break between longer Fireboy and Watergirl runs.

The fun is in finding the solution. Water behaves like water: it runs along slopes, drips off edges and splashes when it falls too far, so the first idea you draw is often not the one that works.

How to play

This game is played by drawing, not by moving a character. Press and drag with the mouse, or use a finger on a touchscreen, to sketch a line on the playfield. Once you let go, the line becomes a solid object and the water starts to flow. The arrow-key controls listed for some other games on this site do not apply here.

A round goes like this: look at where the water starts and where the glass is, work out which obstacles are in the way, then draw a ramp, a channel or a wall that carries the flow across. If the glass fills, the level is complete. If the water spills away, restart and try a different shape.

The game rewards economy. The listing says that using less ink earns more stars, so a short, clean line is worth more than a scribble that happens to work.

Tips

• Study the level before you touch it. Note the gaps, ledges and any hazards, because a line drawn without a plan usually wastes ink.
• Think in slopes. A gentle, continuous slope guides water far better than a flat shelf, which lets it pool and spill over the end.
• Use the line as a funnel. A shallow cup shape under the stream can collect a wide flow and release it toward the glass.
• If your attempt almost works, change the angle slightly instead of redrawing everything. Small tweaks often fix a splash that missed.
