Water Jug Puzzle: what to know before playing
Read the position before choosing your next action. Measure the target number of litres using two unmarked jugs and only filling, emptying and pouring. Try the rule on the board, then read the next instruction. 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
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.
