Happy Glass Game

Happy Glass is a physics puzzle game about getting water into a glass, one hand-drawn line at a time. Water pours from a pipe near the top of the screen, and it's up to you to sketch a path — a ramp, a funnel, a wall — that steers it down into the glass waiting somewhere below.

The twist is that fewer strokes score better. Almost any level can be solved with one long, messy scribble, but the star rating rewards a shorter, cleaner shape, so a lot of the fun comes from replaying a level once you've seen exactly how the water moves and finding a tighter solution. Later levels add spikes, moving platforms, and awkwardly placed glasses that punish a careless line.

Controls

• Click and hold, then drag to draw a line
• Release the line to let the water start flowing
• On a touchscreen, tap and hold to draw the same way

Tips

• Watch one full drop of water before drawing anything — most levels are about timing and angle, not raw line length.
• Draw one continuous line instead of several short pieces; it's easier to control and scores better than a patchwork of strokes.
• Let the glass's own rim or nearby walls do some of the work instead of building a full ramp from scratch.
• If a level feels impossible, restart it — the same layout usually has a much shorter solution than your first attempt.

It suits short sessions well: easy to pick up for a few minutes, with over 650 levels if you end up wanting a lot more of them.
