This Sudoku Game Is Made in C++ using Bracktracking algorithm This repo consists of file It includes a graphical GUI as well as a text based version.
Run Sudoku_end.cpp to play sudoku.
BACKTRACKING is simply reverting back to the previous step or solution as soon as we determine that our current solution cannot be continued into a complete one. We will use this principle of backtracking to implement the following algorithm.
Starting with an incomplete board:
- Find some empty space
- Attempt to place the digits 1-9 in that space
- Check if that digit is valid in the current spot based on the current board
- a. If the digit is valid, recursively attempt to fill the board using steps 1-3.
b. If it is not valid, reset the square you just filled and go back to the previous step. - Once the board is full by the definition of this algorithm we have found a solution.
we will finish the algorithm and continue to understand by running through our code step by step. We will use a recursive function to implement the algorithm In part 2 (look below) we will implement the entire algorithm with the GUI to show the visuall implimentaion of the game.
Hope You Will Like The Game. also u can use the code to make your own version of game.
