Build a steady rhythm
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. Make the next step deliberately.
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. On a smaller screen, keep the active part of the board within view. Look at the feedback after the action.
A useful 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. Take a moment to compare.
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.
