How to play Shikaku
Start Shikaku by looking at the playing area and its controls. Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Use the example below to understand a decision. Begin with the solo mode shown on the page. Look at what changes after your first action.
Solve ten 5×5 rectangle puzzles. Each clue belongs to exactly one rectangle of the stated area.
Keep the aim in sight
Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules. Use the example to check your reasoning.
Your goal
Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Read that aim before choosing your first action. Review the board or playing area as it changes.
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. On a smaller screen, keep the active part of the board within view. Return to the rules if the result is unexpected.
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. Take a moment to compare.
Watch out for this
No rectangle may contain two clues or overlap another. A different version of the game may use a different rule. 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.
