How to play Water Jug Puzzle
Use the controls beside the game rather than guessing the rules. Measure the target number of litres using two unmarked jugs and only filling, emptying and pouring. The game area remains available above the explanation. Choose one of six capacity-and-target puzzles. Both jugs begin empty.
Six verified solvable capacity puzzles, with undo and move count. These are six levels of one game, not six separate games.
Practice with a purpose
A pour stops when the source is empty or the destination is full. It cannot stop at an arbitrary amount. Keep the goal in mind before your next move.
Understand the aim
Keep the goal in view while choosing a move. Measure the target number of litres using two unmarked jugs and only filling, emptying and pouring.
A walkthrough of the rules
- Choose one of six capacity-and-target puzzles. Both jugs begin empty.
- Fill a jug to its capacity, empty it completely, or pour from one jug into the other.
- A pour stops when the source is empty or the destination is full. It cannot stop at an arbitrary amount.

Your inputs

See the idea in action
Keep the goal in view while choosing a move. With 3- and 5-litre jugs, fill the 5-litre jug and pour into the 3-litre jug. The 5-litre jug now contains 2 litres. The game area remains available above the explanation.
Avoid this misunderstanding
Read the position before choosing your next action. You cannot measure a partial fill directly. Only the allowed actions can create a quantity. Try the rule on the board, then read the next instruction.
