The glass is empty and feeling unhappy about it! This container is only happy when it's filled to the brim! In Happy Glass, you mustn’t let this fragile character sit with such sadness. It has a purpose, and it wants to be fulfilled in carrying out this purpose. Can you help the glass capture all the falling water? It can't reach the tap, so grab your pencil and draw lines to control the flow of the water. Redirect the steam to fill the little glass. See? It looks happy again!

Happy Glass is an entertaining puzzle game with 100 levels and cute graphics. As the player, your objective is to grab a pencil and draw a line to manipulate the flow of the water to fill the glass. Each level has a tap, some platforms, and a glass perched somewhere at a little distance from the tap. To draw a line, use the left mouse button. Draw a shelf from the tap to the glass but pay attention to the platforms that lie between them. There are a few things that you should keep in mind while drawing a line. First of all, you can't draw multiple lines. You can only draw one continuous line. When you let go of the left mouse button the tap will be turned on and the water will start flowing. Remember that when you stop drawing, the line will be moved by both the gravity and the flow of the water. Use the platforms around the level to secure the line so that it will stay in place. Another thing you should pay attention to is the way the platforms are laid out. They usually function as both an obstacle and a means to support your drawings. Study and use your environment to solve the puzzle and fill the glass to the marked line. Once you fill the glass, you’ve completed the level and can move on to the next.

The Happy Glass might look a little sad or worried now and then, but it is genuinely delighted when it is filled with water! If you enjoyed this title, try out Happy Glass 2 or challenge yourself with some similar free puzzle games Kizi has on offer!
