An introduction to playing Water Jug Puzzle
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.
Six verified solvable capacity puzzles, with undo and move count. These are six levels of one game, not six separate games.
A small practice goal
A pour stops when the source is empty or the destination is full. It cannot stop at an arbitrary amount. Start a new round when you are ready to try again.
