Exercise for your brain! Try a Sudoku puzzle! Built using Unity and C#

Sudoku is a famous logic-based puzzle. The objective is to fill a 9x9 board with each row, column, and 3x3 grid containing the numbers 1 - 9. Each row, column, and 3x3 grid must only contain one of each number. The fewer clues the initial puzzle has the more challenging the Sudoku is to solve.

I decided to create this application after having some trouble solving the Sudoku Hackerranck problem. I was having a hard time understanding how many of the posted solutions worked. The algorithm used to solve Sudoku puzzles is a recursive backtracking algorithm. Creating this application helped break down the problem and I now better understand how recursive backtracking works.

The development of Sudoku allowed me to improve my programming knowledge, in particular recursion. I also practiced C# programming.
