The glass in the virtual space liked to experience the endless feeling of happiness and you will see it again in Happy Filled Glass 4. The hero wants you to fill it with life-giving fresh water to the brim marked with a dotted line. You draw lines with a black felt-tip pen where you see fit, but at the same time you must take into account and count on where the flow of water will go and not spill precious drops past the glass. If the liquid fills the glass below a certain level, you will have to start over from the beginning of the task of this level in Happy Filled Glass 4.
