First release!(10)
Only the current version so far — new entries appear as the game ships updates.
The objective of the game is to fill the tank with the specified amount of water.
Fill the tank with water so that the level matches the numbers in each column and row.
Tap an empty square in the tank to pour water into it.
Each tap fills the tank by one square’s height.
(You can also pour water by pressing and holding. Use this method if you want to fill the tank quickly.)
Tap a filled section of the tank to remove one square’s height of water from it.
If you enable the X-mark toggle at the bottom of the screen, you can mark a section of the tank with an X.
Use this when you think, “This column doesn’t need any more water.”
Press the Reset button in the upper-right corner of the screen to restart the level from the beginning.
Can you clear all the levels?
