Our glass is sad. No wonder – it has been standing on the shelf for so many days and all this time there has been no drop of water in it. Glasses love water. Therefore, the easiest way to cheer this depressed fellow up is to pour some water into it. But this won’t be so easy. Each level is a tricky puzzle. You’ll have to think and figure out where to draw a line so that the water flows directly into our transparent friend. At first, you’ll do with just basic logical thinking, but on tougher levels you’ll also have to know the laws of physics. Plenty of fascinating tasks will allow you to improve your wit and imagination!
