Happy Glass is a physics‑based puzzle game where your goal is simple: fill an empty glass with water and make it smile again. You do this by drawing lines that guide the water from a faucet to the glass, avoiding spills along the way.

The game starts with straightforward setups, but each new level adds more obstacles — moving platforms, tricky angles, and gaps that force you to think creatively. The water flows in real time, so your lines must both guide and protect it until the glass is full.

Core Mechanics

• Draw paths or barriers using your finger or mouse.
• Direct the water stream into the glass.
• Avoid letting too much water escape.

Every level can be solved in more than one way, but efficiency matters. Using fewer lines or finding a faster route earns higher ratings. The game rewards experimentation, so replaying a level to find a cleaner solution is part of the fun.

Tip: Focus on controlling the first few drops of water — if they flow correctly, the rest will follow. The official game doesn’t include cheats, though hacked versions exist with unlimited hints or instant level completion, which remove the challenge that makes Happy Glass satisfying.
