Follow the steps for Shikaku

Try a more deliberate round

Before your first action, say what you are trying to achieve. Then compare the result with the goal. Keep the objective visible.

What you are aiming for

Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Keep that objective in view throughout the round. Follow this game’s rules rather than another version’s.

How to proceed

  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.

Input guidance

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. Contact us with the game and device if a control does not respond.

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. Take a moment to compare.

Avoid this misunderstanding

No rectangle may contain two clues or overlap another. Compare the situation with the worked example. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
