Happy Glass is a puzzle game with minimal graphics and lots of fascinating levels. On each of them, there will be a glass and a pipe along which water flows. The glass is always sad, and to cheer it, you need to put water in and fill the hero. To do this, you need to draw a road for water to get it exactly in a glass. At first, it is quite easy to do this, but the difficulty with each new level will increase, and on the way to the goal, there will be obstacles. Therefore, the player must thoroughly strain the gyrus and complete the task.
