Your guide to Water Jug Puzzle
Begin with the basic rule, then follow the result of your action. Measure the target number of litres using two unmarked jugs and only filling, emptying and pouring. Start a new round when you are ready to try again. Choose one of six capacity-and-target puzzles. Both jugs begin empty. Keep the goal in mind before your next move.
Six verified solvable capacity puzzles, with undo and move count. These are six levels of one game, not six separate games.
A small practice goal
Keep the goal in view while choosing a move. 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.
What you are aiming for
Measure the target number of litres using two unmarked jugs and only filling, emptying and pouring. Try the rule on the board, then read the next instruction.
How to proceed
- 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.
- Reach the target quantity in either jug. Undo lets you try another route.
Making selections and moves
Take a moment to check the current turn. Use Fill A, Fill B, Empty A, Empty B, Pour A → B and Pour B → A. The display shows current and maximum litres.
One way to understand the rules
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. Start a new round when you are ready to try again.
A mistake to avoid
The board gives you the information needed for the next action. You cannot measure a partial fill directly. Only the allowed actions can create a quantity. The game area remains available above the explanation.
