SudokuDS is a Sudoku game with medium difficulty. This is the first DS homebrew project by Mad and it is written in C.
Fill a 9×9 grid with digits so that each column, each row, and each of the nine 3×3 sub-grids that compose the grid (also called boxes, blocks, regions, or sub-squares) contains all of the digits from 1 to 9.
In this DS version you can quickly check if you have made any mistake by pressing Start.
