Learn the rules of 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. 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.
Practice beyond the first move
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 objective
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. Keep the controls in easy reach.
How a round unfolds
- 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.
Keyboard and screen 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. Check any mode label before starting.
See how the rules apply
A clue 6 may occupy a 2×3 rectangle when other clues allow it. Compare this with the rule that governs the move. Read the matching step again.
Pay attention to this rule
No rectangle may contain two clues or overlap another. Take a moment to reassess the position before continuing. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
