Happy Glass : Fill the Glass by Draw Lines is a casual physics puzzle game where you draw lines to guide water into a waiting glass. Each level gives you a starting position for the water and a sad glass that must be filled to a target line. Your goal is to sketch one or more paths that use gravity, bounce, and simple mechanics to deliver the liquid and make the glass happy.
Levels introduce obstacles such as blocks, ramps, valves, and moving parts that change how water flows. You must plan simple, creative solutions that balance speed and precision. The game rewards efficient solutions and clever thinking, so you can replay levels to improve your result. Controls are simple and intuitive, making the game easy to pick up for players of all ages.
Gameplay focuses on experimentation and problem solving. Draw stable lines to support water flow, block leaks, or create channels. The physics engine reacts realistically to your sketches, so each stroke affects the outcome. This creates a satisfying loop of try, adjust, and succeed that keeps players engaged across many puzzles.
