Sudoku World: Number Puzzle

Sudoku World is classic sudoku, played somewhere worth sitting for a while.

No timers. No pressure. Just a clean, readable board, a pencil, and as long as you want to think. It all works offline, so a tunnel, a plane or a waiting room is as good a place to play as your sofa.

SIX WORLDS TO BUILD
Every puzzle you solve stands a crate in your world. A low-poly harbour town, a castle valley, a safari savanna, a frontier, frozen peaks, and finally the cosmos. Six worlds, 100 levels each, drifting gently past behind the board while you play.

600 HAND-GRADED PUZZLES
Every puzzle is generated, solved and graded before it ships, so a difficulty means the same thing every time. Five of them:
- Gentle: solvable by simple scanning alone
- Easy: no pencil marks needed
- Medium: for when you want to think
- Hard: real technique required
- Expert: bring everything you know

Gentle and Easy are built for beginners learning sudoku; Hard and Expert are there when you want a fight.

A NEW PUZZLE EVERY DAY
A daily challenge with its own streak, and a lucky wheel with a free spin every hour.

PLAY IT YOUR WAY
- Pencil notes, with smart auto-fill when you want it
- Undo as far back as you like
- Matching numbers and peers highlighted
- Hints when you are stuck, never forced on you
- Check-as-you-go, optional and off by default

PLAYS OFFLINE
No connection required. All 600 puzzles, the daily challenge and your whole world live on your device, so nothing stops when the signal does.

DECORATE YOUR WORLD
Coins come from playing. Spend them on perks, or on ornaments that stay in your world: flower beds, standing stones, footbridges, a dragon spire. A piggy bank fills up while you are away.

TAKE IT WITH YOU
Sign in with Google Play Games and your progress follows you to any device, with achievements and leaderboards if you like that sort of thing.

NUMBERS BY ANY NAME
Sudoku has gone by number place, su doku, and plain number puzzle. Whatever you call it, it is the same 9x9 logic puzzle: one to nine, once each, in every row, every column and every box. A brain game and brain training that rewards patience over speed, and a quiet way to spend ten minutes.

Sudoku World is free to play. Optional rewarded videos can top up your coins, and you never have to watch one.
