# Sudoku Games

Free online sudoku from gentle dailies to expert grids: fill every row, column and 3×3 box with one through nine — no repeats, no guessing.

Sudoku needs little introduction: fill the grid so every row, column and 3×3 box contains the digits one through nine exactly once. This group covers the classic 9×9 format, a compact mini variant, and puzzles that refresh daily.

Good solving is scanning, not guessing: find the rows, columns or boxes missing only a single digit, and pencil candidates where a number has just two possible homes. Small certainties cascade into finished grids.

Difficulty labels come from the catalog, and each page states the input style — some games want you to tap a cell first, others pick the number first — so check before you start.
