Understand the basics of 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. Look at what changes after your first action. 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.

Bring this focus to a round

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. Keep the objective visible.

Aim for this result

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. Return to the instructions when a step is unclear.

Step by step

  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.

Choosing and moving on screen

Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. On a smaller screen, keep the active part of the board within view. Make sure you are interacting with the game rather than the surrounding page.

A useful example

A clue 6 may occupy a 2×3 rectangle when other clues allow it. Use the example as a guide rather than a substitute for reading your board. Consider the next action carefully.

An important reminder

No rectangle may contain two clues or overlap another. A different version of the game may use a different rule. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
