Look first. Then listen.
Each round assigns a bottle from 120 shapes. Bodies, necks, heights and capacities vary. Use “Listen to this bottle” beneath the bottle to hear it go from empty to full.
The match hides the bottle and water level. Hold “Pour” to let water flow and release to pause. You can pour in several bursts. Choose “See result” to reveal your level and the opponent’s.
Fill it up or Hardline
- Fill it up
- Get as close to full as possible without exceeding the bottle’s capacity.
- Hardline · HARD
- Remember a red line at a random height. The line disappears while you pour.
- Outcome
- The smaller target error wins. Equal errors draw. Exceeding capacity means failure.
Same bottle. Same target.
Challenge an opponent record for the same bottle and target. A smaller error wins; equal errors draw. There is no need to wait for another player to connect.
You may add a nickname and share your record after a match. A friend can choose to challenge that same bottle and target. Sharing is optional.

Questions
Why preview the sound?
The same pour time fills different bottles by different amounts. Preview this bottle’s sound to get a reference.
Is half the height half the volume?
No. A wide body or narrow neck changes the relationship. Target volume comes from the bottle’s internal shape.
What if I cannot hear anything?
Click the preview yourself, check device volume and tab muting, then contact us with your device and browser if it still fails.
