Rules of the game: The playing field is a square of 9 × 9, divided into smaller squares with a side of 3 cells. 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. In Sudoku, you are 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 is encountered only once.
The Sudoku application supports 4 difficulty modes: 1. Easy is a simple level. 2. Medium - the average level. 3. Hard - a complex level. 4. Expert - super complex level.
In Sudoku also you can save and watch your results.
