How to play Shikaku

Try Shikaku at your own pace and keep its objective in view. Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Keep the game area visible while you use its controls. Check the rule that explains your first action. Choose a clear next step rather than rushing through the instructions.

Solve ten 5×5 rectangle puzzles. Each clue belongs to exactly one rectangle of the stated area.

Make the controls familiar

Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart. Use the example to check your reasoning.

Your goal

Cover the board with non-overlapping rectangles, each containing one clue equal to its area. An attractive position is not enough unless the goal is met. Notice how the game responds to your input.

Step by step

1. Choose a rectangle’s opposite corners.
2. It must contain one clue and have the matching area.
3. Click an existing rectangle to remove it.
4. 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. A careful first action helps you become familiar with the layout. Check any mode label before starting.

A useful example

A clue 6 may occupy a 2×3 rectangle when other clues allow it. Your next round may have a different position, so inspect it before acting. Look for the relevant detail.

Watch out for this

No rectangle may contain two clues or overlap another. Compare the situation with the worked example. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
