About the game
Happy Glass: Draw to Fill turns a blank screen into plumbing. A glass sits somewhere with a dashed line across it, water arrives from above or the side, and nothing connects the two until you draw the connection. Your strokes harden into surfaces the stream can slide along or knock against, so a tilted line becomes a chute and a short hook becomes a stopper.
The level clears once the water climbs above that dashed mark. Let too much of it escape and the attempt is spent, which is where the thinking lives: a steeper angle moves water faster, a flatter one keeps it on the line longer. The glass holds a neutral expression until the level is met, then it beams. A failed sketch costs only a redraw.
How to play
- Draw with your finger or the mouse. Every stroke becomes a solid surface.
- Angle your lines into ramps and channels that carry the stream toward the glass.
- Raise the water past the dashed line on the glass to clear the level.
- Keep spills down, and redraw a sketch that loses too much water.
