How to play Shikaku
Start Shikaku by looking at the playing area and its controls. Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Check the relevant rule before repeating a move. Treat the first round as a chance to learn the controls. 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.
Read before acting
Read one step at a time and try it on the playing area. Match the instruction to the control you use. Keep the objective visible.
