FloodFill method not working properly. (Recursion) - recursion

Question

I am trying to make minesweeper game. Everything is working fine except the floodFill method. Once the floodFill method reveals one number, the recursion stops. I do not want the recursion to stop but go on so that it checks other neighbors as well but it does not. I am not sure what I am doing wrong.
