Understand the basics of 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. Use the example below to understand a decision. Identify the playing area and the controls you need. 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.

Try a more deliberate round

Before your first action, say what you are trying to achieve. Then compare the result with the goal. Use the example to check your reasoning.

What you need to achieve

Cover the board with non-overlapping rectangles, each containing one clue equal to its area. The feedback beside the game helps you follow the round. Keep the controls in easy reach.

How a round unfolds

  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.

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. Read a button’s label before selecting it. Use one clear input at a time.

Learn from a sample situation

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. Notice the change in the playing area.

Keep this in mind

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.
