What does an ordinary glass cup need for happiness? It is just to be filled to the brim with some kind of liquid. Today in the game EG Happy Glass you will be engaged in this. You will see the kitchen in front of you. Somewhere in a certain place there will be a sad empty glass. In another place there will be a tap from which water will flow if it is opened. You will need to draw a line using a special pencil so that it begins under the tap and ends above the edge of the glass. As soon as you make it the water will flow from the tap and if you draw the line correctly, then rolling down it will fill the glass to the brim.
