Game Introduction:

This is a clever liquid-measuring game ! Given a 5-liter cup and a 3-liter cup, how can you measure exactly 4 liters of water? You start with two empty cups and can perform three actions: fill a cup to the brim, empty it completely, or pour from one cup to the other until either the first cup is empty or the second is full.

Game Instruction:

Left-click to choose a cup

After select a cup , Right-click to pour water

There is nothing extra, only pure puzzles.

Euclid whispered this game idea in my dream (true story).
