Sudoku Classic on the nine-by-nine board
Fill each row, column, and 3 by 3 block with digits 1 to 9, then pick a star-marked difficulty that fits your pace. The puzzle works through elimination, so every clue cuts down the possible answers and keeps the board tightly connected.
Tap a square, choose a number, and use the helper button if you want the marked cell filled for you. A double click clears entries again, which makes it easy to test a line, fix a box, and keep your notes open while you search for singles.
That same row-column-box logic is the heart of logic games, and this one keeps the focus on deduction instead of speed. You can play in your browser with no download, no signup, and a layout that works well on mobile and desktop.
If you want a close match, Classic Sudoku Puzzle uses the same 9 by 9 structure and the same placement rules.
Sudoku Puzzle Master leans on the same deduction flow, especially when you scan rows and boxes for the missing digit.
Super Sudoku keeps the familiar grid intact, so the challenge still comes from careful number placement.
Start with the most crowded section, then trace each empty cell across its row, column, and block before you commit. Because one number can solve several intersections at once, a careful pass often opens the rest of the board faster than guessing.
