Why Grafite Sudoku

A sudoku made to be as nice to look at as it is to play, and to respect the people who play it.

No ads, no account

No banners, no forced videos, no sign-up. The app is supported by a coffee from whoever wants to offer one.

Five ways to play

Classic, X-Sudoku with the diagonals, Jigsaw with irregular regions, 12×12 and City, the skyscrapers puzzle.

Sudoku Academy

Dozens of lessons on the grid, exercises from real puzzles and a final exam. In a game, the "Which technique?" help tells you what to look for without giving away the number.

Paper themes

Several paper textures for the grid, from cream to chalkboard, so you play on a page that feels real.

Levels, records and trophies

Every game earns experience. The game celebrates your personal bests, with dozens of trophies and avatars to unlock.

Daily Challenge and Time Attack

A new puzzle every day, with your day streak, and timed games at rising difficulty.

Duel your friends

Send your game's code to a friend: same puzzle, times compared.

Seven languages

English, Italian, Spanish, Portuguese, Indonesian, German and French.

Waiting for you in the full app

Every milestone unlocks a travel companion: nine avatar lines, each with several stages of growth.
