Wikipedia Description

A standard Sudoku puzzle contains 81 cells, in a 9 by 9 grid, and has 9 zones, each zone being the intersection of the first, middle, or last 3 rows, and the first, middle, or last 3 columns. Each cell may contain a number from one to nine; each number can only occur once in each zone, row, and column of the grid. At the beginning of the game, many cells begin with numbers in them, and the goal is to fill in the remaining cells. Players may use a wide range of strategies to solve Sudoku puzzles, and this article goes over a number of methods for doing so.Backtracking algorithms are adapted to solve the Sudoku that iterates all the possible solutions for the given sudoku. If the solutions assigned do not lead to the solution of Sudoku, the algorithm discards the solutions and rollbacks to the original solutions and retries again and hence the name backtracking.Below is the general pseudocode of backtracking algorithm for standard sudoku template (9x9) https://en.wikipedia.org/wiki/Sudoku_solving_alg...
