(This post was last modified: May-03-2023, 04:41 PM by freethrownucleus.)
How can I set a counter for a number of wins? (Probably two different counters.)
If I win, my number of wins increases. If computer wins, its number of wins increases.
Also, following the counters of wins, if I win, there should be the message "You win!", if computer wins, there should be the message "You lose!".

In your tkinter version you have a lot of code that gets repeated over and over. That is always a bad thing. Examining the code you'll notice that you are making a 3x3 tic-tac-toe board 6 times. You should write the code once and reuse 6 times.

Yes I agree with you. But if you saw my last reply, I'd rather stick to pygame than tkinter.
I managed to make a cross shaped pattern by using pygame if you saw last reply.
I gave up trying to combine more sides of a cube for a win because of your proof (how exactly minimax with alpha-beta pruning works).
Also, thanks for help once more! :)

I don't think that is the way o draw a tic-tac-toe board in pygame. You should not be drawing vectors. I did it that way because you wanted something that looked like an orthogonal view of a Rubic's cube. The "Squares" were not square, nor were they squares. It was a painting of a cube that did nothing to simplify programming.
For a tic-tac-toe board made up of square shaped Squares, I would write something that looks a lot like the programs above written in tkinter. I think I mentioned that to you a while ago. I would write a special Square sprite that can display an X or an O. You could place these sprites anywhere you wanted on the board. You could use the map idea which is very popular in pygame circles. You could manually position each square or you could make a class like the Board in my previous example that really just positions a group of squares.
Pygame is written around the concept of sprits, and the more you use sprites the easier it is to write pygame programs. If you make everthing a sprite, you can refresh your screen with one command. If you want to find out what square is clicked, you c an have pygame do all the math. I would use sprites for everything. The squares, player instructions, the score sheet, everything.
This is a very rough pass at writing tic-tac-toe in pygame. Lucily I has some image files that I use a long while ago to write a similar game in tkinter, drawing on a canvas. To play, you will have to proivide your own image files,

How can I easily to change the code so the game doesn't stop after making the winning combination.
But what I want to make is next:
-> the winner is a player who scores the winning combinations on two neighboring boards (sides of the cube)
So there could be a case when one player won on one board and the other player on the other board and then a game continues until someone win on one board and it should be neighboring to the first board.
I had an idea where I used boards' indexes but I didn't know what to do next.
