Ultimate Tic Tac Toe A.K.A. Tic Tactics

My attempt at this challenge., incorporating lessons from this question, which turned out into a much bigger project than I anticipated, but it works. I'll definitely be refactoring most of this in the future, maybe going the MVC route. I tried a lot of new things here and am curious which are good and which are far removed from such.

Concerns:

• Clarity in variable and method names.

• Redundancies.

• Anything unnecessarily convoluted.

• General efficiency of this approach.

• Edge Cases- Again, everything works, but I can't help but think there's something I've not encompassed in the code.

• General improvements/feedback welcomed.

The code will follow the screenshot, with imports included to facilitate things.

The Winner enum

public enum Winner {
    NONE(""),
    X("-fx-color: darkred;"),
    O("-fx-color: gold"),
    TIE("-fx-color: orangered;");

    private final String style;

    Winner(String style) {
        this.style = style;
    }

    public String getStyle() {
        return style;
    }
}

The Player enum

public enum Player {
    X("-fx-text-fill: darkred;"),
    O("-fx-text-fill: gold;");

    private final String style;

    Player(String style) {
        this.style = style;
    }

    public String getStyle() {
        return style;
    }
}

The Position enum

public enum Position {
    TOP_LEFT,
    TOP_MIDDLE,
    TOP_RIGHT,
    MIDDLE_LEFT,
    MIDDLE,
    MIDDLE_RIGHT,
    BOTTOM_LEFT,
    BOTTOM_MIDDLE,
    BOTTOM_RIGHT;
}

The Tic Tac Toe Square Class

```
import javafx.scene.control.Button;

public class TicTacToeSquare {
private Button button = new Button();
private final int SQUARE_LENGTH = 70;

TicTacToeSquare(TicTacticsGame game, TicTacToeBoard board, Position position) {
button.setMinSize(SQUARE_LENGTH, SQUARE_LENGTH);
button.setOnAction(e -> {
if (button.getText().isEmpty()) {
button.setText(game.getCurrentPlayer().toString());
but

final Keyword

The Game, Tic Tac Toe Board, Tic Tac Toe Board, all have fields which are assigned but never reassigned,

private StringProperty xPlayer = new SimpleStringProperty("X player");
private StringProperty oPlayer = new SimpleStringProperty("O player");
private TicTacticsGame game;
private Button button = new Button();

They could all use the final keyword.

Generally

The code is fairly easy to read, you follow most conventions. Overall a pleasant surprise to look at.
