How to play 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. Choose a clear next step rather than rushing through the instructions. Begin with the solo mode shown on the page. Check the relevant rule before repeating a move.
Solve ten 5×5 rectangle puzzles. Each clue belongs to exactly one rectangle of the stated area.
Read before acting
Read one step at a time and try it on the playing area. Match the instruction to the control you use. Make the next step deliberately.
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. Check the rules when you are unsure.
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. Use the control method described here for this activity. Use the visible help when you are unsure of the next input.
A useful example
A clue 6 may occupy a 2×3 rectangle when other clues allow it. Apply the same reasoning to the position in your own round. Verify the rule before continuing.
Watch out for this
No rectangle may contain two clues or overlap another. A different version of the game may use a different rule. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
