Happy glass is a puzzle game with limited challenges, but the variations are rather smart and interesting. Graphics are rather fun, and the rules are simple here. There is an empty glass which you will see on the screen. You have to fill it up with water. In order to do it, you are expected to draw just a single line. When you manage to achieve the result, you will see how this glass is smiling to you. There are plenty of ways to do it, and you are expected to find the best one. You can find your unique solution. Thus, thinking outside the box is required. Do not buy into the deceptively simple challenge. You are suggested 300 levels and some of them are really difficult. You will enjoy playing it, and the developer promises to offer new levels coming soon.

Though, graphics are pretty simple, the images are rather stylish. There is a primitive glass with a cute face looking like it is taken from some children’s book. In addition, there are bars and a source of water with the flow of a stream which should be directed in such a way to get right into a glass. You have to draw a line which shows this direction.

There are several details which you would better keep in mind. In order to draw a line, you need some ink, and its consumption influences your score. You should think before using it, because the less ink you use, the more stars you have. Another point is that if you build a badly balanced structure, a glass can fall and that is not good.

The game includes a dynamic mechanism which makes drawing lines easy. Take advantage of the minimalist approach and some features. For instance, you will earn coins when complete a level and can spend them on buying pencils and colored ink. Also, you can buy coins spending real money.
