This is a new sequel of this game called Happy Filled Glass 4. Like the previous parts you have to fill the glass with liquid that is on a platform. Above it at a certain height you will see a water tap. You will need to carefully examine everything. Now with the mouse you will have to draw a line. After that, the faucet will open. If you draw a line at the right angle, then the water will roll down it into the glass and fill it to the brim. As soon as you do this, you will be given points in the game Happy Filled Glass 4.
