This project is used to solve regular 9x9 sudoku. After you press green flag, input the sudoku that you wqnt to be solved (e.g.: 300104008005000200082509410204080605000206000803090107076901850008000700500807006). Than wait a moment. A few 'pop' sound would be heard after the computer have solved the sudoku. The solution can be seen in the list 'answer' (e.g.: 397124568145368279682579413214783695759216384863495127476931852938652741521847936). Have fun!
I didn't use any techinque of solving sudoku. I just use the rules of sudoku and 'trial and error'. For example, if the first cell is blank, the computer guess if it is 1, would it contract with other cell? If no, then keep on guess the second blank cell. If yes, then first cell should not be 1.
