Shikaku Kingdom: Logic Puzzles

Shikaku Kingdom is a logic puzzle game where every board you solve becomes part of a city. Draw rectangles on a numbered grid, and when the grid is done it folds up into buildings on your kingdom map.

How it works:
- Draw rectangles so that each one holds exactly one number.
- The number is the rectangle's area.
- Every cell belongs to one rectangle.
Every level has exactly one solution, so there is always a logical way through and no guessing. Shikaku is a classic Japanese number puzzle, sometimes called the rectangles puzzle, and a good brain puzzle for a few quiet minutes or a long evening. The tutorial takes five small 4x4 boards. The Master boards take a lot longer.

A STORY TOLD IN PAPER
Folio was a kingdom drawn by hand, until the Ink Tide washed it blank. Wren sets out to redraw it, guided by the notes of the mapmaker Oda and by Kite, a paper crane. The story runs through 13 illustrated chapters (260 levels) in four acts: The Blank Shore, The Lantern Quarter, The Ink Tower and The Frontier. After the epilogue the map keeps going, with endless isles and a new named isle every 20 levels.

LEVELS
- 2,000 levels graded from Easy to Master
- Boards from 5x5 up to 10x14, growing chapter by chapter
- Every chapter ends with a boss level: a dark ink board with its own intro card
- Past level 2,000, new levels are generated on your device, so the puzzles don't run out

THE DAILY DISPATCH
One daily puzzle, and everyone in Folio gets the same board. It grows through the week, from 6x6 on Monday to 10x10 on Sunday. Keep your streak going (up to 2 streak freezes cover a missed day) and share your result as text that doesn't spoil the board.

HINTS AND CONTROLS
Kite shows you the next rectangle that has to be there and tells you why, for example "Only one rectangle fits this 5." Hints come from chests or cost coins, and you earn coins by solving levels. Short on both? An optional short video can give you a hint. A Time Freeze adds time to a level's par, so a slow solve can still earn three stars. Undo and redo are always there. If dragging feels fiddly, switch to drawing by tapping two corners.

SETTINGS AND SOUND
- Every level has its own melody, and each rectangle you place plays a note
- Color-blind palette, light, dark or automatic theme, haptics, and separate music and sound switches
- An optional reminder, once a day at the time you pick
- Works offline with no account. Your progress stays on your device
- Available in 15 languages

ADS AND PURCHASES
Shikaku Kingdom is free to play with ads. Ads between levels never interrupt a puzzle, don't appear in your first sessions, and are capped at 8 a day. Videos that give you coins, hints, a streak freeze or a level skip are optional.
Optional in-app purchases let you remove the ads between levels, add coins, buy the coins saved in the Treasury once it is full, or get a one-time starter pack with coins, hints and Time Freezes. You never need to buy anything to move forward: every level can be played for free.
