Mathematics of Sudoku
A completed Sudoku grid is a special type of Latin square with the additional property of no repeated values in any of the 9 blocks of contiguous 3×3 cells. The relationship between the two theories is now completely known, after it was proven that a first-order formula that does not mention blocks is valid for Sudoku if and only if it is valid for Latin Squares.
How to solve the puzzle:
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. There are different strategies to solve this puzzle.
* 4 levels - easy, medium, hard, extreme

* Intelligent hints
NOTE: This application FREE to play and supported by ads. Contains in-app purchases.
