You will need physics, logic and dexterity in the game On the Edge. The task seems simple - fill the container with water. But the problem is that you can only open and close the faucet once. No supplement is provided if there is not enough water. You must fill the container at least to the marked level, and at a maximum to the brim, and not a single drop should fall outside the glass. When opening the tap, you must determine by eye how much water you will need in a given case. At each level, the size of the container will change. As is its location in On the Edge.
