Happy Glass
Sketch creative pathways to guide a stream of water into a sad, empty glass. The mechanical challenge lies in balancing ink usage against structural stability, as your hand-drawn lines must withstand the weight of the fluid.
About This Game
Happy Glass is a Fluid-Gravity Simulation and Structural-Sketching puzzle. The core logic uses a Particle-Based Liquid Engine and Rigid-Body Drawing: your hand-drawn lines act as solid colliders with mass and friction. It emphasizes Mass-Distribution Logic and "Flow-Path Optimization."
How to Play
Draw a line to guide the water from the pipe into the glass. The gameplay is Creative Hydro-Engineering: fill the glass to the "Success Line." Interaction involves Ink-Efficiency Calibration—the game rewards you with more stars for using the shortest possible line to achieve the goal.
Tips & Tricks
High scores (3-Stars) are achieved through "Anchor-Point Engineering." The pro secret is to use "Hook Designs." Instead of drawing a long ramp, draw a small "C-clamp" shape around an existing peg or corner to anchor your structure. This uses 80% less ink and provides a stable, unmoving path for the water particles.
