Making your first moves 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. Look at what changes after your first action. Compare the starting position with the example in the Guide. 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.
A focus for your next round
Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Keep the objective visible.
Aim for this result
Cover the board with non-overlapping rectangles, each containing one clue equal to its area. An attractive position is not enough unless the goal is met. Try to explain the aim in your own words.
How to proceed
- 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.

Try this 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. Look for the relevant detail.
Watch out for this
No rectangle may contain two clues or overlap another. Compare the situation with the worked example. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
