Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Keep that objective in view throughout the round. Return to the instructions when a step is unclear.
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. Use the visible help when you are unsure of the next input.
An example to follow
A clue 6 may occupy a 2×3 rectangle when other clues allow it. Compare this with the rule that governs the move. Choose a deliberate next step.
Avoid this misunderstanding
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.
