Understand the aim
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. Follow this game’s rules rather than another version’s.
How a round unfolds
- 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.
Getting comfortable with the controls
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Use the control method described here for this activity. Avoid pressing the same control repeatedly while a move is being processed.
One way to understand the rules
A clue 6 may occupy a 2×3 rectangle when other clues allow it. Focus on why the action is allowed, not only its outcome. Verify the rule before continuing.
Avoid this misunderstanding
No rectangle may contain two clues or overlap another. Read the feedback to see why an action did not have the expected result. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
