How to play Shikaku
Take a moment with Shikaku before moving to another game. Cover the board with non-overlapping rectangles, each containing one clue equal to its area.

Solve ten 5×5 rectangle puzzles. Each clue belongs to exactly one rectangle of the stated area.
Notice the feedback
Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Make the next step deliberately.
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. Follow this game’s rules rather than another version’s.
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. Keep the playing area visible while using these controls. 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. 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. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
