In the second part of Happy Glass 2, you will continue to help the glasses become happy. To do this, they just need to be filled to the brim with liquid. A playing field will appear on the screen in front of you on which you will see a standing empty glass. At a certain height, you will see a container filled with water. Various objects will be scattered across the playing field, which act as obstacles. You will need to examine everything very carefully. Now, with the help of a special pencil, you can draw a line. As soon as you do this, the container will open. Water hitting the line will roll along it in the direction you specified. As soon as the water is in the glass, and fills it to the brim, you will receive points and proceed to the next level of the Happy Glass 2 game.
