How to play Shikaku
Open Shikaku, check the instructions and begin a round. 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. 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.
