What it does

Play Shikaku online for free at MeowBlock. A cat-themed rectangle partition puzzle — drag to draw rectangles, match numbers, fill the grid. The classic Nikoli puzzle, reimagined with cats.

Play Shikaku online free: draw rectangles to match every number and fill the grid. Cat-themed puzzles from easy to hard, no download, no sign-up.

Each rectangle must contain exactly one number. This level starts with a 3 — it needs a rectangle of exactly 3 cells. Start with prime numbers — their 1×N shape is forced — then work from corners and the largest clues. Each rectangle's area must match its number exactly, and forced placements come first. 2, 3, 5, 7 can only form 1×N rectangles. Place them first — their shape is forced. A "6" can be 1×6, 2×3, 3×2, or 6×1. Learn which shapes fit where. Each rectangle's area must equal its number. No more, no fewer. 3×3 grids with guided hints. Learn rectangle placement, area rules, and elimination basics. 5×5 grids with simple shapes. Practice prime numbers and corner strategies at your own…from gridpaw.com
