In the third part of Happy Glass 3, you will continue to fill glasses of various sizes and capacities with water. A playing field will appear on the screen in front of you on which a glass will be located in a certain place. It will stand on the platform and will be empty. There will be a tap with water at a certain distance. A variety of objects will also be scattered on the field. You will have to consider their position. Now, with the help of a special pencil, you will need to draw a specific line. As soon as you do this, the tap will open. If you did everything correctly, then the water will slide down the line into the glass. This will bring you a certain number of points and you will move on to the next more difficult level of the game.
