Sudoku

Sudoku game written in Python with the Pygame library to visualize the backtracking algorithm.

Every time the program is executed, a random, solvable board is created and the user can attempt to solve it by clicking on the cells. Entering a number into a cell will be entered as a tentative value. Once the the user is sure that the inputted number is the correct entry, pressing the enter key will attempt to input the number onto the board. Correct answers will be permanently displayed while incorrect answers will be removed. Likewise, values can be removed by pressing on the backspace or delete keys.

If at any point the player decides to solve the board, the spacebar can be pressed. This will commence a visual that demonstrates how the backtracking algorithm is being applied in order to solve the board.
