Shikaku [Rectangles]

Find where every rectangle belongs.

Shikaku is a logic puzzle with a simple rule: fill the grid with rectangles, each containing exactly one number. That number tells you the size of the rectangle. Fill the grid without gaps or overlaps, and every piece falls into place. Easy to learn and satisfying to solve, Shikaku offers a quick relaxing break with Puzzle Packs or a challenge you can dive into with Time Trials.

Shikaku has NO ADS and NO SUBSCRIPTIONS.
