How to play Shikaku
Bring your attention to one round of Shikaku. Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Choose a clear next step rather than rushing through the instructions. Compare the starting position with the example in the Guide. Keep the game area visible while you use its controls.
Solve ten 5×5 rectangle puzzles. Each clue belongs to exactly one rectangle of the stated area.
A useful comparison
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Refer to the controls when needed.
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. Try to explain the aim in your own words.
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. Read a button’s label before selecting it. A new-round button replaces the current round.
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. Choose a deliberate next step.
Watch out for this
No rectangle may contain two clues or overlap another. Read the feedback to see why an action did not have the expected result. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
