#
You have a recursion issue. The creation of a Spaces object creates a win object and the creation of a win object creates a Spaces object. You can have one create another during its creation; but, the other cannot create one of a type that creates it during its creation. In fact, your win class should not create any other game related worlds unless it is only for the purpose of restarting the game. Remove lines 10 thru 18 in the win class.

Now that I took a closer look and actually can tell what you are doing, I can tell you that it would be a whole lot easier if you used a 3 by 3 int array in your world to track the state of the world. You can use zero (the default int value) for an unused space, positive one for one player and negative one (or two) for the other. Checking for game over should be a breeze then. But I would use the act method in the world class for that -- not the win object.

Remove line 1. There is no need to import the java.util package. Line 22 is misplaced. You do not need to create a win object until it is determined that there is a win state. It seems you are trying to do a whole lot for something that could be quite simple. I can understand (maybe) having a Space class -- but 9 of them is going overboard. You can create 9 objects from a single class:
?
1
2
3
4
private void prepare()
{
    for (int j=0; j<3; j++) for (int i=0; i<3; i++) addObject(new Space(), 100+i*200, 100+j*200);
}
A Space object only needs to accept one, and only one, click. It can inform the world when it is clicked on. Its location in the world is enough to do the rest:
?
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
import greenfoot.*;
 
public class Space extends Actor
{
    boolean clicked;
     
    public void act()
    {
        if (!clicked && Greenfoot.mouseClicked(this))
        {
            clicked = true;
            ((MyWorld)getWorld()).spaceClicked(this);
        }
    }
}
Then, in your world, with a field for whose turn it is:
?
1
private int turn = 1;
you can have something like this:
?
1
2
3
4
5
6
