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. The game features 103 carefully designed puzzles of increasing difficulty, challenging your problem-solving skills step by step.
