When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round. Notice the feedback after each input.
Your goal
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. Take a moment to understand the current position.
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.
How to use 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. Read the example below alongside these instructions.
Work through an example
A clue 6 may occupy a 2×3 rectangle when other clues allow it. Compare this with the rule that governs the move. Check the stated objective.
Avoid this misunderstanding
No rectangle may contain two clues or overlap another. Compare the situation with the worked example. 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.
