Sudoku is a logic-based, combinatorial number-placement puzzle. The playing field is a square of 9х9, divided into smaller squares with a side of 3 cells. Thus, the entire playing field consists of 81 cells. They already at the beginning of the game are some numbers (from 1 to 9), called tips. From the player it is required to fill the free cells with numbers from 1 to 9 so that in each row, in each column and in each small 3х3 square, each digit would occur only once.

The complexity of Sudoku depends on the number of cells initially filled. You can choose the desired level of difficulty from the beginner to the advanced.
