Water Jug Puzzle: what to know before playing
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. 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 focus for your next round
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. Try the rule on the board, then read the next instruction.
Understand the aim
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. The game area remains available above the explanation.
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.
Using the playing area
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.
A closer look at one example
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. The game area remains available above the explanation.
Avoid this misunderstanding
A careful first move helps you understand the round. You cannot measure a partial fill directly. Only the allowed actions can create a quantity. Keep the goal in mind before your next move.
