Game guide · 2COU99BJ
Read before your next round 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. 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.
A small practice goal
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Use the example to check your reasoning.
The goal to keep in mind
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. Try to explain the aim in your own words.
Work through the instructions
- 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.
Making selections and moves
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. A careful first action helps you become familiar with the layout. Contact us with the game and device if a control does not respond.
Try this 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. Keep the game’s format in mind.
Watch out for this
No rectangle may contain two clues or overlap another. Take a moment to reassess the position before continuing. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
