Draw lines to guide water into the glass and make it happy!
Happy Glass: Fill the Glass by Draw Lines is a physics puzzle about guiding water into an empty glass. Each stage presents a new arrangement of pipes, platforms, gaps, and obstacles. You cannot move those objects directly; instead, you draw a line that becomes a solid part of the level when you release it. A good drawing might form a ramp, block a leak, support the glass, or redirect the stream. The challenge is not simply getting some water to the target, but finding an efficient shape that wastes as little ink as possible. Because the physics reacts to every angle and curve, several creative solutions may work.
Study where the water will fall before drawing. Hold and drag to create a line, then release it to start the physics simulation. Guide enough water into the glass to complete the level. If the stream misses or the drawing collapses, restart and adjust the shape or its anchor points.

Drawn lines become physical objects affected by gravity, collisions, and the force of flowing water.
Yes. Any stable drawing that directs enough water into the glass can work, although efficient solutions score better.
Make the final slope gentler or add a small barrier near the rim to reduce the stream's speed.
