An introduction to playing Water Jug Puzzle
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. 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.
An idea for your next attempt
A pour stops when the source is empty or the destination is full. It cannot stop at an arbitrary amount.
The objective of a round
Measure the target number of litres using two unmarked jugs and only filling, emptying and pouring. Keep the goal in mind before your next move.
How a round unfolds
- 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.
Getting comfortable with the controls
Use Fill A, Fill B, Empty A, Empty B, Pour A → B and Pour B → A. The display shows current and maximum litres. The game area remains available above the explanation.
Learn from a sample situation
Use the controls beside the game rather than guessing the rules. 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. Keep the goal in mind before your next move.
Watch out for this
You cannot measure a partial fill directly. Only the allowed actions can create a quantity. Keep the goal in mind before your next move.
