Play Shikaku with the rules at hand
Read the aim of Shikaku, then make your first move. 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. Compare the starting position with the example in the Guide. Look at what changes after your first action.
