How do I add a restart function to a game in Unity?

I have followed and completed a Unity tutorial however once the tutorial is said and done, there was no function mentioned to restart the game.

Other than closing the application and re-opening, how would I go about adding something like this in?

For example you can reload main scene for restart game. 

SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);

There are do ways to restart game in Unity:

1.Reset every useful variables such as position, rotation, score to their default position. When you use this method, instead of #2, you will reduce how much time it take for your game to load.

Create a UI Button then drag it to the resetButton slot in the Editor. 

//Drag button from the Editor to this
public Button resetButton;

Vector3 defaultBallPos;
Quaternion defaultBallRot;
Vector3 defaultBallScale;
int score = 0;


void Start()
{
    //Get the starting/default values
    defaultBallPos = transform.position;
    defaultBallRot = transform.rotation;
    defaultBallScale = transform.localScale;
}

void OnEnable()
{
    //Register Button Event
    resetButton.onClick.AddListener(() => buttonCallBack());
}

private void buttonCallBack()
{
    UnityEngine.Debug.Log("Clicked: " + resetButton.name);
    resetGameData();
}

void resetGameData()
{
    //Reset the position of the ball and set everything to the starting postion
    transform.position = defaultBallPos;
    transform.rotation = defaultBallRot;
    transform.localScale = defaultBallScale;

    //Reset other values below
}

void OnDisable()
{
    //Un-Register Button Event
    resetButton.onClick.RemoveAllListeners();
}

2.Call SceneManager.LoadScene("sceneName"); to load the scene again. You can call this function when Button.onClick.AddListener is called..

Create a UI Button then drag it to the resetButton slot in the Editor. 

//Drag button from the Editor to this
public Button resetButton;

void OnEnable()
{
    //Register Button Event
    resetButton.onClick.AddListener(() => buttonCallBack());
}

private void buttonCallBack()
{
    UnityEngine.Debug.Log("Clicked: " + resetButton.name);

    //Get current scene name
    string scene = SceneManager.GetActiveScene().name;
    //Load it
    SceneManager.LoadScene(scene, LoadSceneMode.Single);
}

void OnDisable()
{
    //Un-Register Button Event
    resetButton.onClick.RemoveAllListeners();
}

The decision to which method to use depends on how much Objects in your scene and how much time it takes your scene to load. If the scene has a huge world with baked light maps and HQ textures then go with #1.
