Tatami - Shikaku Puzzle

Tatami is a shikaku logic puzzle: divide the floor into rectangles, one number in each.

The floor of a Japanese room is bare, and each number is a mat waiting to be laid. Press on a number and drag out a mat. A mat is always a rectangle, it holds exactly one number, and that number is how many squares it covers. Lay mats until no bare floor is left. Each room has a single answer, and careful reasoning alone will find it.

HOW A ROOM PLAYS
• Drag from a number to size its mat. If a mat can't go there, the room tells you why
• Every mat size wears its own colour, so a finished floor reads at a glance
• Tap a mat to lift it again. Undo is free and has no limit
• No clock, no move count, no lives. A room can't be lost, only left for later
• Hint lays the one mat the room already forces, and names the reason: "The 3 fits only here"
• Check lifts every mat that doesn't belong

FOUR HALLS, 160 ROOMS, ALL FREE
• The Tea Room: 5×5 and 6×6 floors to learn the feel
• The Study: 7×7 and 8×8
• The Guest Hall: 9×9 and 10×10
• The Great Hall: 11×11 and 12×12, for long, deep sittings
• Lay most of a hall's rooms and the next one slides open
• Want more? The Garden Pavilion is an optional fifth hall of 100 rooms at 12×12 and 13×13

TODAY'S ROOM: A DAILY PUZZLE
• A fresh room every day, gentle early in the week and deeper by the weekend
• Each day in a row lights another paper lantern on the veranda

DRESS THE ROOM
• Sakura, a cherry-blossom spring, is yours for free
• Lantern Night, Ukiyo-e and Hinoki are optional room themes. Each one changes the scene, the board and the music
• Pick one, or take All Themes for every theme now and any added later

HOW ADS WORK HERE
• Tatami is free to play and supported by ads
• Full-screen ads only come between rooms: none while you play, none in your first session, none after the daily room
• Hint and Check are your choice: watch a short video only when you want one. Your very first Hint is on the house
• Remove Ads clears the banner and the between-room ads. Hint and Check stay just as they are

Every room is already on your phone, so Tatami plays offline too. If you enjoy brain teasers, number puzzles or a quiet, relaxing logic game before bed, the house is open.

Slide the door open. The floor is waiting.
