Happy Glass is a very enjoyable mobile game available for Android devices which requires the player to draw a line and fill up the glass with water from a faucet. This fun game comes with multiple levels and each one has different obstacles that you must bypass in order to make the glass happy with water. You will notice that this virtual glass has a dotted line.
The task is to have enough water and reach the line if you want to complete the level. In terms of controls everything is simple. You get a pencil and you must draw all kinds of lines and shapes to guide the flowing water to your beloved glass. The catch is that the less drawings you make, the more points you're going to be rewarded once you complete the level.
Take a moment and make a smart strategy each time you load a new level because the obstacles change from one mission to another. During your quest, levels will become harder and harder to complete. You can use your experience and advancement through the game in order to change the color of the pencil, glass and even water. With regard to graphics there's not much to say.
The details are very simple and the game will run on most devices out there.
