About Sudoku
Sudoku is a popular Japanese logic-based number placement puzzle.
The objective is to fill the 9x9 grid so that each column, each row, and each of the nine 3x3 boxes (called blocks or regions) contains the digits from 1 to 9. The general way to solve the problem is when you insert a new number it should be unique in that particular region(blocks)and also in that particular row and column. [Read more about Sudoku.]
