         for(j=1;j<=9;j++)
         {
            mat[i][j]=  rand()%9+1;
            cout<<" "<<mat[i][j];

             if(j==3||j==6)
            cout<<"  ";
            if(i==6&&j==9||i==3&&j==9)
            {

Do you mean Sudoku. Here are some thread which has the program Sudoku

[codestorm]

Has anyone here made a GUI based game of Sudoku?

[reka20]

Wow, i haven't try that. maybe i will try to program it. If I'm able to solve the problem i will post it here..

codestorm: try Simple Sudoku. Generates puzzles for you, and you can enter puzzles from teh intarweb, and does all the legwork of maintaining candidate lists, turning moderately complex sudokus from a frustrating exercise in keeping track of potential numbers back to the fun logic puzzle it was meant to be.

[xpi0t0s]

OP: generating and solving sudokus are two completely different tasks. Probably best to work on a solver first, then once you've got the hang of that, turn the rules round to make a generator. You can generate them randomly, but it's probably more efficient in the long run to use the rules "backwards" to generate a puzzle.
