Water Jug Puzzle: from controls to your first round
Read the position before choosing your next 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.
Give this approach a try
A careful first move helps you understand the round. A pour stops when the source is empty or the destination is full. It cannot stop at an arbitrary amount.
The purpose of your moves
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. Keep the goal in mind before your next move.
Start here and follow along
- 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.
Keyboard and screen controls
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. Start a new round when you are ready to try again.
Put the rules into context
The example and rules describe the same game you can play above. 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.
Watch out for this
Take a moment to check the current turn. You cannot measure a partial fill directly. Only the allowed actions can create a quantity. Try the rule on the board, then read the next instruction.
