Sudoku Solver

Just started with macros, and yet immediately started a tricky project.
Making a sudoku solver in Excel.
Hereby 2 challenges.
1: How am I going to solve the Sudoku?
2: Hoe ga ik dat aanpakken met een of meerdere macro’s?
At first I started with the simple rules for solving a sudoku.
But gradually I found out that I still had to use a Brute Force method.
In the end I poured Brute Force method into a macro and this is the result.
