Play Sudoku for Free at Brain Metrix. the Sudoku Game, Known Also as Number Place or Nan Pure, is a Logic-Based Placement Puzzle.

 

 

✺ Sudoku is a famous brain teaser.

 

Before you start solving a Sudoku, you need to know what the game is about:

 

✺ Sudoku also known as Number Place or Nanpure, is a logic-based placement puzzle.

The aim of the puzzle is to enter a numerical digit from 1 through 9 in each cell of a 9×9 grid made up of 3×3 subgrids (called ”regions”), starting with various digits given in some cells (the ”givens”); each row, column, and region must contain only one instance of each numeral. Completing the puzzle requires patience and logical ability. Sudoku is sometimes misspelled as (Sodoko, Soduko, Suduko, Suduku).

 

A completed Sudoku grid is a special type of Latin square with the additional property of no repeated values in any 3×3 block.

 

The number of classic 9×9 Sudoku solution grids was shown in 2005 by Bertram Felgenhauer and Frazer Jarvis to be 6,670,903,752,021,072,936,960 [5] (sequence A107739 in OEIS) : this is roughly 0.00012% the number of 9×9 Latin squares.

 

✺ Various other grid sizes have also been enumerated — see the main article for details. The number of essentially different solutions, when symmetries such as rotation, reflection and relabelling are taken into account, was shown by Ed Russell and Frazer Jarvis to be just 5,472,730,538 [6] (sequence A109741 in OEIS). Both results have been confirmed by independent authors. A great method of brain stimulation ✺ ✺ ✺
