◆What's Sudoku?
Sudoku - also known as "Number Place" - is a logic-based, combinatorial number-placement puzzle. The aim of Sudoku is to enter a number from 1 through 9 in each cell of a grid, most frequently a 9×9 grid made up of 3×3 subgrids. Each row, column and region must contain only one instance of each number.

◆What's "CROSS"?
"CROSS" "is a modified Sudoku variant. "CROSS" Sudoku adds to the standard rows, columns and bold-lined boxes by also requiring that you place 1 to 9 (or 1 to whatever the width of the puzzle is) into each of the two main diagonals.

◆What's "JIGSAW"?
"JIGSAW" is a modified Sudoku variant. In a "JIGSAW" Sudoku, these areas are random shapes as opposed to squares. The areas will always contain nine cells, so that the same standard Sudoku rules can still apply.
