Water Jug Puzzle: from controls to your first round
Take a moment to check the current turn. 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
The board gives you the information needed for the next action. 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.

How to interact with the game
Begin with the basic rule, then follow the result of your action. 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.
An example before you play
A careful first move helps you understand the round. 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.
Where a round can go wrong
Use the controls beside the game rather than guessing the rules. You cannot measure a partial fill directly. Only the allowed actions can create a quantity. Keep the goal in mind before your next move.
