How to play Shikaku
Choose a round of Shikaku and settle into its rules. 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. Use the example below to understand a decision.
Solve ten 5×5 rectangle puzzles. Each clue belongs to exactly one rectangle of the stated area.

What counts as success
Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Keep that objective in view throughout the round. Try to explain the aim in your own words.
Work through the instructions
- 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.
Making selections and moves
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Use the control method described here for this activity. Use one clear input at a time.
See how the rules apply
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. Verify the rule before continuing.
One detail worth checking
No rectangle may contain two clues or overlap another. Take a moment to reassess the position before continuing. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
