Happy Glass
Draw containers to guide water into a glass in this relaxing physics puzzle. Account for flow direction and pooling when sketching your solutions. Watching the glass fill up to the target line never stops being satisfying.
Draw containers with thick walls since thin lines break under water pressure more easily. Account for gravity when designing your water channel since liquid flows downward. Start drawing from the water source and work toward the glass to ensure continuous flow.
How to Play Happy Glass
Each level shows a water source and an empty glass that you must fill by drawing containers and channels. Your drawings become physical objects that interact with realistic water physics. Guide the water flow around obstacles and through your constructed channels into the target glass. Fill the glass to the indicated line to complete each level.
