The challenge in front of you
Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Read that aim before choosing your first action. Try to explain the aim in your own words.
Follow these playing steps
- 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.
Using the playing area
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. Avoid pressing the same control repeatedly while a move is being processed.
A closer look at one example
A clue 6 may occupy a 2×3 rectangle when other clues allow it. Apply the same reasoning to the position in your own round. Look for the relevant detail.
A mistake to avoid
No rectangle may contain two clues or overlap another. Take a moment to reassess the position before continuing. Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round.
