Game title: Sudoku Puzzle
The game is a puzzle with numbers. The player can choose the difficulty of the game, picking up the size of the playing field – the bigger field is, the more difficult game the player gets. The field has many squares that consist of 9 more squares. There are some numbers in the square so the player needs to put other numbers there too, but in a special way – in each row, each column, and each small 3×3 square each digit occurs only once. The game is over when all numbers are in their places.
