Water Jug Puzzle: learn through an example
A careful first move helps you understand the round. 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. 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.
Take a closer look while playing
Take a moment to check the current turn. 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 counts as success
The board gives you the information needed for the next action. 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.
From the start of a round
- 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
Keep the goal in view while choosing a move. 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
Begin with the basic rule, then follow the result of your action. 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. Try the rule on the board, then read the next instruction.
Where a round can go wrong
Begin with the basic rule, then follow the result of your action. You cannot measure a partial fill directly. Only the allowed actions can create a quantity. Start a new round when you are ready to try again.
