Solve your way.
Keep track of possibilities with the tools beside your grid. Your current puzzles and notes are saved in your browser.


Optional solution assistance is off by default. If you enable it in Options, after five seconds in a grid you can ask the game to complete it. A confirmation appears before completion, and assisted results are marked in your progress.
Complete different puzzles to unlock six short cards about the history of Sudoku. Cards you have earned stay unlocked when you restart a puzzle.

Switch between soft paper and night themes, with matching panels and text. Original music uses synthesized plucked-string and flute timbres inspired by Japanese instruments. Music and effects have separate controls.
