Tatami is a Shikaku puzzle game for iPhone with a paper-and-ink look. Every day brings five 9x9 grids and every week a set of 30 larger ones, the same for every player in the world. Between dailies there are 750 puzzles in five packs from 5x5 to 9x9.
About Tatami: Logic Puzzles
Tatami is Shikaku, a classic Japanese logic puzzle. The grid is scattered with numbers, and you divide it into rectangles so that each rectangle contains exactly one number and covers exactly that many squares. Every puzzle has a single answer, checked by hand, and no guessing is needed.
The Today screen holds five new 9x9 puzzles each day, and This Week a set of 30 larger grids from 9x9 to 11x11. Both are the same for every player worldwide. Finishing all of the day's puzzles before midnight keeps your streak going.
Beside the dailies sit five packs of 150 puzzles each, named after Japanese crafts and arts: Hajimari (5x5, gentle), Origami (6x6), Shibori (7x7), Kintsugi (8x8) and Karesansui (9x9, master). A Time Trial mode races your best time across mixed sizes. Finished rectangles fill in with flat, bright colours and thick ink outlines on cream paper, with serif numerals.
Tatami is made by Huetic, the studio behind Eulerian, and came out in May 2026. The listing says it shows no ads while you play and needs no timer, but the App Store marks it as containing advertising and sells a Remove Ads upgrade. Hints are optional: watch a short ad for a free one or buy packs in the Store.
How to play Tatami: Logic Puzzles
- Open Tatami and tap Today for the day's five grids, or This Week for the weekly set.
- Pick a number and drag out a rectangle around it whose area equals that number.
- Make sure every rectangle holds exactly one number.
- Keep going until every square of the grid belongs to a rectangle.
- Finish all five of the day's puzzles before midnight to keep your streak.

Tips
- Start with numbers that can only fit one way, such as a large number squeezed against an edge.
- A prime number such as 5 or 7 can only be a single row or column, which cuts its options sharply.
- Squares that only one number can reach must belong to that number's rectangle.
- Corners are good places to begin: a corner square has few numbers able to cover it.
