sudøku
A focused Sudoku app built around the pleasure of solving. Fresh puzzles are generated directly on your device, with thoughtful tools when you want them and a clean board when you do not.
Made for the puzzle
sudøku is designed to make everyday solving comfortable: choose a difficulty, settle into the board, and use as much or as little assistance as suits you.
Fresh puzzles, made on your device
Puzzles are generated and validated locally, giving you a self-contained supply of boards without relying on a puzzle catalogue in the cloud.
A board designed for concentration
Clear controls, readable numbers, thoughtful feedback, and carefully chosen interactions keep attention on the solve.
Four difficulty levels
Choose the level that fits the moment, from a relaxed solve to a more demanding puzzle.
Useful, local statistics
Follow your solving history and performance while keeping the experience personal and on your device.
Thoughtful solving tools
Notes, hints, pause protection, error review, and a short correction window support real play without crowding the board.
Your look, your pace
Light and dark appearance, multiple color themes, and optional assistance let the app adapt to how you like to solve.
See sudøku in action
The app stays visually quiet while still giving you the controls and feedback you need while solving.
Offline by design
The core Sudoku experience runs on your device. Puzzle generation, solving logic, active games, and statistics do not depend on a puzzle backend or a user account. That keeps the game fast, resilient, and pleasantly self-contained.
The free version may use platform services for advertising and purchases; those services are separate from the on-device puzzle engine. See the privacy statement for details.
Simply a good Sudoku
A polished puzzle, useful tools, fair choices, and technology that stays in the background. That is the whole idea.
