Rules, controls and help for Shikaku

One thing to notice as you play
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. Keep the objective visible.

- It must contain one clue and have the matching area.

An example before you play
A clue 6 may occupy a 2×3 rectangle when other clues allow it. Apply the same reasoning to the position in your own round. Read the matching step again.
