+## Sudoku Solver GUI
+
+# Overview
+This is a simple Sudoku Solver implemented in Python with a graphical user interface (GUI) using the Tkinter library. The Sudoku Solver allows you to input a Sudoku puzzle and then solves it using a backtracking algorithm. You can visualize the solution step by step on the GUI.
+
+# Features
+Interactive GUI: The Sudoku Solver features a user-friendly interface built with Tkinter, allowing you to input Sudoku puzzles and visualize the solution.
+Backtracking Algorithm: The Sudoku Solver uses a backtracking algorithm to find the solution to the input puzzle.
+Step-by-Step Solution: You can click the "Solve" button to start solving the Sudoku puzzle step by step, and observe how the solver fills in the cells.
+
+# How to Run
+Make sure you have Python installed on your system.
+Clone this repository or download the sudoku_solver.py file.
+Open a terminal or command prompt and navigate to the directory containing sudoku_solver.py.
+Run the command python sudoku_solver.py.
+The Sudoku Solver GUI window will open, allowing you to input Sudoku puzzles and visualize the solution.
+
+# How to Use
+When the Sudoku Solver GUI window opens, you'll see a 9x9 grid representing the Sudoku puzzle.
+enter value row by row in terminal ,empty space is denote by '0'.
+After entering the puzzle, click the "Solve" button to start solving the Sudoku puzzle.
+You can observe how the solver fills in the cells step by step. Once the puzzle is solved, you'll see the complete solution on the GUI.
+Additional Notes
+The Sudoku Solver uses a backtracking algorithm to find the solution to the puzzle. It tries different numbers in each cell and backtracks if it reaches a dead-end.
+You can input any valid Sudoku puzzle into the solver, and it will find the solution if one exists.
+If there are multiple solutions to the puzzle, the solver will find one of them.
+The GUI provides visual feedback on the solution process, making it easy to understand how the solver works.
+Enjoy using the Sudoku Solver GUI!
