For many the Sudoku game is a Japanese game, however it is a Swiss mathematician Leonhard Euler, who is considered its creator. It is believed that he was who gave rise to the Sudoku as a hobby, creating a series of guidelines for the calculation of probabilities.
For all of us who have studied Physics, mathematics ,engineering or economy, talking about Euler is like in football talking about Johan Cruyff ,we know what we are talking about!
Trying to create a Sudoku generator in Excel as well as a Sudoku solver, became a personal challenge. It was fantastic to present it in Excel, a mathematical game that should be able to be played and solved in the best existing calculator, Excel itself.
Easy presented in an Excel sheet whose resolution could be use many of the existing functions, we carried out the first Sudoku solver in 2004-2005.
We tested it with hundred of Sudoku puzzles to see if it worked or hung in resolution, however, we observed that one Sudoku solver in Excel could solve any Sudoku puzzle.
To date, we have not been able to find a single puzzle not been able to be solve. The vast majority of them can be solve in less than 3 seconds and for programs or people interested to learn VBA, it can be useful.
This solver is the most downloaded among Sudoku solvers made in Excel-VBA
