Your goal
Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Keep that objective in view throughout the round. Follow this game’s rules rather than another version’s.
Step by step
- 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.
Controls
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. A careful first action helps you become familiar with the layout. Make sure you are interacting with the game rather than the surrounding page.
A useful example
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. Look for the relevant detail.
Watch out for this
No rectangle may contain two clues or overlap another. Check the rule before repeating the action. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
