About the game

Happy Glass: Draw to Fill is a puzzle game where the glass only smiles when the water goes past the dotted line. You draw the path with your finger or mouse: a line can be a ramp, a channel, or a stopper that redirects the stream.

Each level gives you an empty glass and a stream you have to guide. If you spill too much water, the attempt is lost, so the angle of every stroke matters. You can erase and draw again as many times as you want. The bright colors and the glass's face changing as it fills keep the challenge relaxed.

How to play

  • Draw with your finger or mouse: each stroke becomes a solid surface the water can slide down or hit.
  • Tilt the lines to make ramps and channels that carry the water to the glass.
  • Fill the glass above the dotted line to complete the level.
  • Avoid losing too much water; if a stroke doesn't work, erase it and try another route.
