About Sudokumee
Sudokumee is a focused online Sudoku game built around a simple idea: give players a clean place to solve without unnecessary distractions.
Sudoku without the noise
Sudokumee brings Classic, Diagonal and Killer Sudoku together in one lightweight web experience. The interface stays out of the way while you think, with a clear board, quick controls, difficulty choices and optional hints.
The game is designed to be free to play and does not require an account to start a puzzle.
Built for solving
Puzzles are generated in the browser and checked for a unique solution before they are presented. Killer puzzles are checked against their cage sums too. The game also includes undo, notes, fullscreen play and a Killer cage helper, and it remembers your game so you can pick it up later.
Explain, don't just reveal
Hints explain the reasoning behind a next move instead of silently filling an answer, so they can support learning and solving.
