Who Should Play
In Underline the Water, your main goal is to draw the right lines or shapes in a single attempt to guide water safely into the glass. You may need to build channels, block obstacles, or create supports to stabilize the glass. Once the glass is fully filled with water, the level is successfully completed.
How to Play
In Underline the Water, you solve each level using only a drawing tool. Your drawings help overcome three core challenges:
- Create water paths: When water can’t flow directly into the glass, draw lines or shapes to redirect it and guide it safely to the target.
- Block falling obstacles: Some levels contain orange objects that fall due to gravity and block the water. Draw protective shapes to deflect or stop them from interfering with the flow.
- Stabilize the glass: If the glass is unbalanced or suspended in midair, it may tip over once gravity takes effect. Draw supports or platforms to keep it steady while filling.
⚠️ Important Note:
Your ink supply is limited. The less ink you use, the higher your final score will be.

Frequently Asked Questions
If a level feels too challenging, you can tap the “Hint” button at the bottom of the screen and watch a short ad to receive guidance. A green sample line will appear, showing one possible solution to complete the level.
- Fill the glass correctly: The glass must be completely filled with water. Be careful—if any orange obstacles or drawn shapes fall into the water, the level won’t count as a success, even if the water reaches the top.
- Use as little ink as possible: To earn three stars, keep ink usage low: Using more than 25% of the ink limits you to two stars; Using more than 50% results in one star. So efficient drawings are the key to a perfect score.
