        private void inithelp()
        {
            MessageBox.Show("Pairs, the aim of the game is to match 2 cards in the grid, each player will take it in turns to find a pair, once the card pair has been found it will turn blue. The winner is the player who ends with the most pairs");
        }

        public void initgame()
        {
            for (int row = 0; row < 6; row++)
            {
                for (int col = 0; col <6;col++)
                { 
                    memoryarray[row, col] = 1;
                    if (memoryarray[row, col] == 1)
                    {

                    }
                }
            }
            controlarray = new GImageArray(this, memoryarray, 35, 200, 10, 200, 10, imagepath);
            controlarray.Which_Element_Clicked += new GImageArray.ImageClickedEventHandler(Which_Element_Clicked);
        }
   




        private void Which_Element_Clicked(object sender, EventArgs e)
        {
            int row = controlarray.Get_Row(sender);
            int col = controlarray.Get_Col(sender);

        }
        private void assigncardstogrid()
        {
