The objective of the SUDOKU game is to fill a 9 × 9 grid with numbers so that each column, each row, and each of the nine 3 × 3 sub-grids that make up the grid (also called "boxes", "blocks", or "regions") contain all the numbers from 1 to 9. The puzzle installer provides a partially filled grid, which for a well-laid puzzle has a unique solution.
The application offers an unlimited number of grids with solution.
