Sudoku Traditional Puzzle Game

Sudoku — the traditional puzzle game. Smart hints, pencil notes, and a strategy guide — wrapped in a calm board that works in light and dark mode. Designed for iPhone and iPad and tuned for people who love a clean board and a clear head. If you get stuck, a hint showing which cell can be solved next is only a fingertip away. Still no idea? The hint can optionally show the solution strategy to be applied for the next cell, and if the strategy name does not ring a bell, a tap on it will show an explanation. Fill the 9×9 grid so every row, column, and 3×3 box contains each digit from 1 to 9 exactly once. Start easy or push yourself with harder difficulties. Every puzzle has a unique solution and is solvable with pure logic — no guessing required.
