In the standard form of this puzzle type, a 9x9 grid is divided into 3x3 sections with heavy bars. The grid is to be filled with the digits 1 to 9 (some initially provided) so that no number is repeated in a row, column, or outlined region. There are many popular variants on this puzzle type, including ones where the diagonals have to contain 1 to 9, ones where the regions are not square, ones where there are restrictions on which numbers can be adjacent, puzzles of different sizes, and many others.
