Phil, please don't push for more until you've worked through the help you've gotten so far.

I can't make it any easier for you than spelling it out, Phil. It's only a couple of lines.

@phil67rpg do you know how to work with textures in OpenGL? You can draw images in Paint. I use GIMP.
I created this texture atlas in GIMP:
I use texture coordinated to draw selected item:
GL.Begin(PrimitiveType.Triangles);
{
// Left top triangle
GL.TexCoord2(0f, 0f); GL.Vertex2(0f, 0f);
GL.TexCoord2(0f, 0.33f); GL.Vertex2(0f, 64f);
GL.TexCoord2(0.33f, 0f); GL.Vertex2(64f, 0f);
// Right bottom triangle
GL.TexCoord2(0f, 0.33f); GL.Vertex2(0f, 64f);
GL.TexCoord2(0.33f, 0.33f); GL.Vertex2(64f, 64f);
GL.TexCoord2(0.33f, 0f); GL.Vertex2(64f, 0f);
}

well I am working on it sorry I am kind of slow. well I got the x's to be drawn now I have to get the computer to draw the o's thanks for all the help when I get this done I will repost my code.

I have not made the AI for the game but I will try. At first I want to make a network version for two players using TCP sockets.
Source code: https://github.com/8Observer8/TicTacToe_OpenTkOpenGL11CSharp
I draw a game field from 2D character array:
private char[,] _gameField = new char[,]
{
{ ' ', 'x', ' ' },
{ ' ', 'x', ' ' },
{ '0', ' ', ' ' }
};

What version of the book do you have?
