Find your footing in Shikaku
Bring your attention to one round of Shikaku. 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.
Give this approach a try
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. Make the next step deliberately.
What the game asks you to do
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. Take a moment to understand the current position.
Follow these playing steps
- 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.
Choosing and moving on screen
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. 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. Compare this with the rule that governs the move. 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. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
