I'm trying to learn how to use Qt (5.11.1) for GUI applications so I've done a simple memory game where 12 tiles are displayed and every time the user clicks on a tile it will show an image, so they have to match them into 6 pairs of images. There's a countdown of 1 minute. Game ends if the time is up before all 6 pairs have been matched, or if all 6 pairs are matched, only that it will show different messages to the user. There is no next level, saving score or anything, so it's very simple.

I'm trying to learn how to use Qt (5.11.1) for GUI applications so I've done a simple memory game where 12 tiles are displayed and every time the user clicks on a tile it will show an image, so they have to match them into 6 pairs of images. There's a countdown of 1 minute. Game ends if the time is up before all 6 pairs have been matched, or if all 6 pairs are matched, only that it will show different messages to the user. There is no next level, saving score or anything, so it's very simple.

I'm trying to learn how to use Qt (5.11.1) for GUI applications so I've done a simple memory game where 12 tiles are displayed and every time the user clicks on a tile it will show an image, so they have to match them into 6 pairs of images.

There's a countdown of 1 minute. Game ends if the time is up before all 6 pairs have been matched, or if all 6 pairs are matched, only that it will show different messages to the user. There is no next level, saving score or anything, so it's very simple.

C++ Qt simple GUI game

I'm trying to learn how to use Qt (5.11.1) for GUI applications so I've done a simple memory game where 12 tiles are displayed and every time the user clicks on a tile it will show an image, so they have to match them into 6 pairs of images. There's a countdown of 1 minute. Game ends if the time is up before all 6 pairs have been matched, or if all 6 pairs are matched, only that it will show different messages to the user. There is no next level, saving score or anything, so it's very simple.

I know there's room for adding many more features, but would like to know what can be improved from what I've done so far.

My mainwindow.h file:

#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>
#include <QTimer>
#include <QTime>
#include <QString>
#include <QVector>
#include <QHash>
#include <QRandomGenerator>
#include <QPushButton>
#include <QMessageBox>

namespace Ui {
    class MainWindow;
}

class MainWindow : public QMainWindow{
    Q_OBJECT


public:
    explicit MainWindow(QWidget *parent = nullptr);
    ~MainWindow();
    QTimer *timer=new QTimer();
    QTime time;

                              "tile05", "tile06", "tile07", "tile08",
                              "tile09", "tile10", "tile11", "tile12"};
    QHash<QString, QString> tile_image;
    int score=0;
    bool isTurnStarted;
    QPushButton* previousTile;
    QPushButton* currentTile;
    int matchesLeft;
    QMessageBox msgBox;


private slots:
    void updateCountdown();

    void randomize(QVector<QString> &tiles);
