Die doel van die legkaart is om 'n simbool of getal van 1 tot 9 in elke blokkie van die rooster te sit. Gewoonlik bestaan 'n 9x9-rooster uit 3x3-subroosters ('streke'), en 'n aantal simbole of getalle is reeds aangegee ('gegewes'). Elke simbool of getal moet in elke ry, kolom of streek net een keer voorkom. (Bron &lt;http://en.wikipedia.org/wiki/Sudokugt;).
The aim of the puzzle is to enter a symbol or numeral from 1 through 9 in each cell of a grid, most frequently a 9x9 grid made up of 3x3 subgrids (called 'regions'), starting with various symbols or numerals given in some cells (the 'givens'). Each row, column and region must contain only one instance of each symbol or numeral (Source &lt;http://en.wikipedia.org/wiki/Sudokugt;).
