What This Guide Covers
Another common mistake is treating a locally valid shape as globally safe. In Shikaku, one placement can silently damage the remaining board. If a move creates an awkward isolated strip or leaves a nearby clue with impossible dimensions, that move was not really helping.
Players also often underuse the board edges. Borders and corners reduce the number of possible rectangles dramatically. If you ignore those constraints and think only in abstract shapes, you miss some of the easiest deductions available.
The good news is that these mistakes are easy to correct once you start checking rectangles in the right order: clue count, area, overlap, and then board-wide consequences.
