How to play Fill the Glass
Fill the Glass is a line-drawing physics puzzle. A tap drips water from the top of the screen and a glass waits somewhere below. Draw slides, ramps and funnels with your finger or mouse, then press Pour and watch a few hundred drops follow your lines.
Every level gives you a limited amount of ink, so each line counts. Walls block the way, fire turns water into steam, drains swallow it, and moving bars sweep across the route. Some levels have two taps, a narrow glass or a roof over the glass.
Clear a level when enough water reaches the glass. Earn a second star for saving at least 85 percent of the water and a third for using little ink. If your try fails, your lines stay in place: change them and retry. Hints and extra ink are optional and always come with a normal retry.
Controls
Drag with the mouse to draw a line. Space or Enter: pour or retry. Z: undo. E: eraser. C: clear. H: hint. P or Esc: pause. M: sound.
Drag a finger to draw lines, then tap Pour. Use Undo, Erase and Clear at the bottom. Retry keeps your lines.
FAQ
What happens if I run out of ink?
The line stops growing. Undo or erase a line to get its ink back, or watch an optional video for 35 percent more ink after a failed try.
Do I lose my lines when I retry?
No. Retry only resets the water. Use Clear to start from an empty screen.
How do I get three stars?
Clear the level, save at least 85 percent of the water and use 65 percent of the ink or less.
What does fire do to water?
Water that touches fire is lost as steam. Drains also swallow it. Lead the water around both.
Is Fill the Glass free?
Yes. It is free to play in your browser, with no download and no account.
Can I play on my phone?
Yes. It runs on phones, tablets and computers. Drag a finger to draw lines, then tap Pour. Use Undo, Erase and Clear at the bottom. Retry keeps your lines.
