Key features
- Fifteen themed worlds — kingdoms, creatures, runes, gems, sushi and more — each with its own art, not a palette swap
- Four difficulties, from a gentle first board to expert
- Every piece readable by silhouette at a glance; landscape worlds use irregular hand-shaped areas instead of square boxes
- Rows, areas and finished boards come alive as you complete them
- A findable move always exists — every difficulty, every step of a correct solve. No guessing, ever
- A hint that points before it tells: first press spotlights where to look, second press reveals
- No timers, no lives, no fail state. Solve times feed the records board only if you want them to
Sudoku World is Sudoku with the numbers taken out and something worth looking at put in their place. You are not filling in a grid — you are raising a tiny kingdom, stocking an aquarium, laying out a dungeon, growing a garden.
Underneath, it is the real thing: fair, unique-solution 9×9 Sudoku. The rule never changes. Each row, each column and each area holds exactly one of every piece.
Fifteen worlds
Tiny Kingdoms. Magic Runes. Garden. Creature Habitats. Dungeon Builder. Aquarium. Space Colony. Alchemy Lab. Bento Box. Pirate Treasure. Monster Collection. Toy Box. Elements. Gem Vault. The Cast.
Each one is drawn its own way rather than recoloured, and every piece is built to be read by its silhouette at a glance — never slower to recognise than a digit. The worlds that look like landscapes use irregular, hand-shaped areas instead of square boxes, so the board reads as a place rather than a spreadsheet.
The payoff
Complete a row and it lights up. Complete an area and the pieces inside it come to life. Complete the board and the whole thing blooms at once. That moment is the reason this isn't a reskin.
Never stuck, never rushed
Every board is built so that at every single point along a correct solve, there is at least one square you can work out in one look. No guessing, no forced chains, no dead ends — on any difficulty. Harder simply means the find is rarer and better hidden.
Stuck anyway? The hint asks first and answers second: one press spotlights where to look without spoiling it, a second press fills the square in.
And nothing is chasing you. There is no countdown, no life meter and no way to lose. Your solve times feed the records board if you want them to, and you can turn the clock off entirely if you don't.
