THE IDEA
A small rule with room to think.
This is Sudoku with the familiar 9×9 grid kept clear and readable. Choose from Easy through Master, use pencil marks to plan, and ask for a hint when a puzzle stops moving.
Daily streaks, XP, achievements, and leaderboards add a sense of progress without changing the logic at the center. Each puzzle has a unique solution and room for both quick practice and serious solving.
