About Sudoku
The playing field is a grid with 9x9 cells, divided into smaller grids with a side of 3 cells. Thus, the entire playing field consists of 81 cells. At the beginning of the game, there are already some numbers in them (from 1 to 9). The player is required to fill in the free cells with numbers from 1 to 9 so that in each row, in each column and in each small 3 ×3 square, each digit would occur only once. There are multiple levels of difficulty you can choose. Beware of mistakes you can make.
Expect thinky at its core, with a streak of puzzle and casual woven through the design. Loading time and performance depend on the game, your device, and your connection.
Two quick pointers before you dive deep: Read the puzzle objective before making your first move. If the rules reward combos, compare their value with the other ways to make progress.

Frequently asked questions
Is Sudoku free to play?
Access to Sudoku on Glaze Games is free. Features inside the embedded game follow the publisher's own rules and may include ads or optional purchases.
Do I need to download anything to play Sudoku?
The browser edition of Sudoku loads on this page. Use a browser supported by the game and allow time for its files to load.
Can I play Sudoku on my phone?

Only where your school's rules permit it and the network allows both Glaze Games and the embedded publisher. Glaze Games cannot bypass network filters. An adult should review the game's content and ads before choosing it for children.
