The Shikaku playbook
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. Use the example below to understand a decision. Read the objective before making your first input. Choose a clear next step rather than rushing through the instructions.
Solve ten 5×5 rectangle puzzles. Each clue belongs to exactly one rectangle of the stated area.
Try a more deliberate round
When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round. Notice the feedback after each input.
The purpose of your moves
Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Read that aim before choosing your first action. Start with a deliberate move.
Making your moves
- 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.
Keyboard and screen 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. Make sure you are interacting with the game rather than the surrounding page.
An example to follow
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. Choose a deliberate next step.
A useful caution
No rectangle may contain two clues or overlap another. Read the feedback to see why an action did not have the expected result. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
