Sudoku

Our free daily · new every day Sudoku A fresh grid every day, at five levels Play now

No pencil required: pick a number, tap an empty cell, and place it. The goal is the sudoku everyone already knows — fill the 9x9 grid so each row, column, and 3x3 box holds every digit from 1 to 9 with nothing repeated. No theme, no twist, just the puzzle in its standard form, which is exactly what you want when a variant isn't what you're after.
