Follow the steps for Shikaku
Try Shikaku at your own pace and keep its objective in view. 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.

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.

See the idea in action
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. Read the matching step again.
Where a round can go wrong
No rectangle may contain two clues or overlap another. Compare the situation with the worked example. After a move, check what changed. Decide which rule explains the new state before acting again.
