Show that you can fill all the glasses again in Happy Glass 3. In this game, the goal is to get the water from the pump to the glass by drawing lines. If the water in the glass rises above the line, you have completed the level. The more you draw, the fewer stars you earn, so try to use your pencil sparingly. There are a total of 30 levels you can play. As you progress through the levels, you will encounter various obstacles and challenges, such as large blocks, hot plates, and water tunnels.
