Sudoku is one of the most searched browser games on the web, with around 2,740,000 searches every month. If you have already played it to death — or it is blocked on your school or office network — you are probably hunting for something that scratches the same itch.
We went through our library and picked 8 games genuinely similar to sudoku. Every one is free, loads straight in your browser, and needs no download or sign-up.
What Makes Sudoku So Popular?
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.
That combination — instant loading, simple controls, and “one more try” pacing — is exactly what we looked for in the alternatives below.
