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. Choose one of six capacity-and-target puzzles. Both jugs begin empty. Try the rule on the board, then read the next instruction.
Six verified solvable capacity puzzles, with undo and move count. These are six levels of one game, not six separate games.
Practice beyond the first move
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. The game area remains available above the explanation.
What you need to achieve
The example and rules describe the same game you can play above. Measure the target number of litres using two unmarked jugs and only filling, emptying and pouring. The game area remains available above the explanation.
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.
How your actions work
A careful first move helps you understand the round. Use Fill A, Fill B, Empty A, Empty B, Pour A → B and Pour B → A. The display shows current and maximum litres.
Follow the example
