Happy Glass - Draw to Fill

The pitch

Happy Glass: Draw to Fill is a creative and relaxing puzzle game where your goal is to fill a happy glass with water — but there's a twist! You must draw lines and shapes to guide the water flow into the glass. Think strategically, draw creatively, and use physics to your advantage as you solve increasingly challenging levels. The game features colorful visuals, satisfying animations, and a joyful glass that smiles only when full. Whether you're a fan of brain teasers or just love doodling your way through clever puzzles, this game is sure to entertain and test your ingenuity.

Controls & how it runs

Use your finger or mouse to draw lines or shapes on the screen. These drawings will act as paths, ramps, or barriers to guide the water into the glass. The goal is to fill the glass above the dashed line without spilling too much water. Think carefully and use your imagination to solve each level — and don’t forget, the glass only smiles when it’s full!

Getting a run going takes exactly one press: Press start, up top, and the game boots inside this page — nothing downloads in the background and no form wants your details before the first jump. The cabinet is drawn for a flexible screen and listens to mouse, keyboard or touch, whichever the game prefers. It reshapes itself for tall and wide screens alike, so phone, tablet and desktop all get the full picture. Given a fullscreen button, use it — scores look better at full size, that's just science.

Pro tips for puzzle cabinets

• Count what's missing, not what's there. In matching and logic boards the empty spaces and absent pieces usually draw the shape of the solution for you.
• Solve the corner first. Constrained edges and locked pieces have the fewest options, which makes them the honest starting point of almost every board here.
• If you're stuck, change the order, not the plan. Many boards on this row are the same moves played in a different sequence — the lock was the order all along.
