Play Water Jug Puzzle with the rules at hand
Take a moment to check the current turn. 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. 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.
Something to practise
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.
Understand the aim
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.
Work through the instructions
- 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.
Getting comfortable with the controls
The board gives you the information needed for the 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. Keep the goal in mind before your next move.
Work through an example
Read the position before choosing your next action. 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. Start a new round when you are ready to try again.
Check this before moving on
Read the position before choosing your next action. You cannot measure a partial fill directly. Only the allowed actions can create a quantity. Start a new round when you are ready to try again.
