How to play Shikaku
Shikaku gives you a focused activity to play in your browser. Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Use the example below to understand a decision. Make your first input carefully and watch the result. 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.
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. Notice the feedback after each input.
Your goal
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. 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.
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. Avoid pressing the same control repeatedly while a move is being processed.
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. Consider the next action carefully.
Watch out for this
No rectangle may contain two clues or overlap another. Take a moment to reassess the position before continuing. 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.
