For many people Sudoku is a Japanese game, but it is a Swiss mathematician “Leonhard Euler” who is considered its creator (Euler — Wikipedia)
It is believed that it was he who originated the Sudoku pastime, creating a series of guidelines for the calculation of probabilities.
For those of us who have studied Physics, Mathematics, Any Engineering, Economics, Business and/or… talking about Euler is like talking about Johan Cruyff in Holland.
Trying to create a Sudoku Generator in Excel, as well as a Sudoku Solver in Excel, became a personal challenge.
It was great to expose it and/or present it in Excel, a mathematical game that logically should be able to be played and solved, in the best existing calculator, that is to say in EXCEL.
A Game easily presentable in an Excel sheet, for whose resolution we could use many of the existing functions in Excel.
The first Sudokus Solver was made in 2004/2005, more as a personal challenge.
We tested it with hundreds of Sudokus to see if it worked and/or hung in its resolution. But we observed that our Sudoku solver in Excel was able to solve any Sudoku.
To this day we have not been able to find a single Sudoku that we have not been able to solve, the vast majority of them in less than 3 seconds.
For Programmers and/or people interested in learning VBA, it can be useful.
I understand that this solver is the most downloaded of the Sudoku Solvers made in Excel/VBA.
What is Sudoku?
The Sudoku Game is a very old game and very often and worked every day by millions of people around the world, also known as südoku, su-doku or his doku, is the hobby (crossword) Japanese fashion logical type, which we can find in countless magazines and newspapers.
The rules of Sudoku game are simple, consists of a grid of 9×9 cells, divided into 9 quadrants of 3×3, which must be filled so that all rows, columns and quadrants (sets of 3×3 cells) have the numbers from 1 to 9 without any repetition.
Obviously one starts from a board started with several cells covered by numbers. In order to be correct, Sudokus must have a unique solution as well as rotational symmetry. Therefore it is important to have a Sudoku solver like the present one in our web page, so that people who are not able to solve Sudoku as well as for those who want to verify what has been done can have this Sudoku solver that can be downloaded OnLine and is also free.
