Follow the steps for Shikaku
Read the aim of Shikaku, then make your first move. Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Keep the game area visible while you use its controls. 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.
One thing to notice as you play
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. 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.
How to use the 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. Use the visible help when you are unsure of the next input.
Follow the example
A clue 6 may occupy a 2×3 rectangle when other clues allow it. Focus on why the action is allowed, not only its outcome. Notice the change in the playing area.
A mistake to avoid
No rectangle may contain two clues or overlap another. A different version of the game may use a different rule. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
