Water Jug Puzzle: instructions and practice
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. 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.
A focus for your next round
Begin with the basic rule, then follow the result of your action. 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.

Step by step
- 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.
Making selections and moves
Read the position before choosing your next action. 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
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. Try the rule on the board, then read the next instruction.
A common point of confusion
Keep the goal in view while choosing a move. 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.
