بالطبع، ها هو الجزء المتبقي من الكود:

```python
    draw_grid()
    pygame.display.flip()

    # Main loop
    running = True
    while running:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                running = False
            elif event.type == pygame.MOUSEBUTTONDOWN:
                mouse_pos = pygame.mouse.get_pos()
                clicked_row = mouse_pos[1] // TILE_SIZE
                clicked_col = mouse_pos[0] // TILE_SIZE
                grid[clicked_row][clicked_col] = random.choice([2, 4])

        screen.fill(WHITE)
        draw_grid()
        draw_numbers(grid)
        pygame.display.flip()

    pygame.quit()

if __name__ == "__main__":
    main()
```
