Take a closer look while playing
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Make the next step deliberately.
What counts as success
Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Use the instructions to see which actions move you towards it. Notice how the game responds to your input.
The steps to play
- Choose a rectangle’s opposite corners.
- It must contain one clue and have the matching area.
- Click an existing rectangle to remove it.
- Cover every square to finish.
How your actions work
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Read a button’s label before selecting it. Use one clear input at a time.
Put the rules into context
A clue 6 may occupy a 2×3 rectangle when other clues allow it. Use the example as a guide rather than a substitute for reading your board. Check the stated objective.
An important reminder
No rectangle may contain two clues or overlap another. Take a moment to reassess the position before continuing. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
