How to play Shikaku
Choose a round of Shikaku and settle into its rules. Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Choose a clear next step rather than rushing through the instructions. Make your first input carefully and watch the result. 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.
Build a steady rhythm
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. Use the example to check your reasoning.
