About this game

Game Introduction

Sudoku Classic Number Puzzle is a timeless logic game that challenges players to fill a 9x9 grid with digits. The grid is divided into nine 3x3 blocks.

This puzzle type is known for improving concentration and logical thinking. The game offers a satisfying mental workout suitable for all ages. Players can enjoy the puzzle at their own pace with no time pressure. The clean interface and straightforward rules make it easy to start playing immediately. Whether you are new to puzzles or an experienced solver, this game provides a relaxing yet engaging experience.

How to Play

To play, first choose a difficulty level such as Easy, Medium, Hard, or Expert. A 9x9 grid appears with some cells already filled. Players select a number from a toolbar and then click or tap the empty cell where they want to place it. Numbers can also be dragged from the toolbar to a cell. The core rule is that no number can repeat in any row, column, or 3x3 block. If a mistake is made, a number can be removed by dragging it back to the toolbar or using an erase option if available. There is no timer, so players can solve puzzles at their own pace.
