A clean logic puzzle built around rectangles

Shikaku looks simple, but every number controls a precise area. The best solves come from narrowing possible rectangle shapes, spotting forced placements, and keeping the board tidy.

1

One clue per rectangle

Every region you draw must contain exactly one number clue.

2

Area equals the clue

A clue of 6 means the rectangle must cover exactly six cells.

3

Cover the full board

Finish when every cell belongs to one valid rectangle and no regions overlap.

Pick up a puzzle

Fill rectangles so each number equals the area of its rectangle.
