Flyclops Domino! Bone Randomization Code

random.cs

// for Unity (C#)
public static void Shuffle<T>(this List<T> list)
{
    System.Random rnd = new System.Random();  
    int n = list.Count;
    while (n > 1) {  
        n--;  
        int k = rnd.Next(n + 1);  
        T obj = list[k];  
        list[k] = list[n];  
        list[n] = obj;  
    } 
}

How is this used to manipulate the dominoes
