C code, Rand is outputting same Number for my while loop but not for my for loop

Hey guys I could use some help, I have been trying to figure this out for a bit of a while now and have looked at tons of other peoples questions and nothing has solved my problem.

When I am making this code for a random dice roller, I want to get a random number until I get three 6's on the dice. For some reason this produces the same number for all runs, but on my for loop it works. Can I get some help getting this to work?

If you have another random generator to use please include a example I have not managed to find any other option, otherwise I would not of asked for help.

The pesky While loop in question:

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int Ran(int max) {
return (rand() % max)+ 1;
}

int main(){

    int max = 6;
    int nsuc = 0, ncount = 0;
    int matt = 40;
    srand((unsigned) time(0));

    for(int i = 1; i <= 20; i++){
        while(!(nsuc >= 3)){
            int nr = Ran(max);
            if(nr < matt){
                ncount++;
                if(nr == 6){
                    nsuc++;
                }
            }
        }
        printf("Number of rolls until 3 6's = %d\n", ncount);
    }
}

The for Loop that works:

#include <stdio.h>
#include <stdlib.h>
#include <time.h>


void Shuffle() {
srand((unsigned) time(0));
}

int Ran(int max) {
return (rand() % max)+ 1;
}

void binomial(int run, int max, int btrials, int *array, int scount){

    for(int j = 1; j<=run; j++){
        for (int i=1;i<=btrials;i++){
            int r = Ran(max);
            if(r == 6){
            scount++;
            }
        //printf("Trial %i, roll = %d\n",i , r);
        }
        array[j-1] = scount;
        scount = 0;
        //printf("\nEnd of Run %d\n\n",j);
    }

}

int main(){

    int Runs;
    printf("How many runs do you want to do? > ");
    scanf("%d", &Runs);
    printf("\n");

    int bdist[20];
    int distcount = 0;
    int max = 6;
    int btrials = 20;
    int suc[Runs+1];
    int scount = 0;

    int ncount = 0, nsuc = 0;
    int matt = 40;


    Shuffle();
    binomial(Runs, max, btrials, suc, scount);

    printf("All counts of succesful 6 rolls.\n");

     for(int k = 0; k<=btrials; k++){
        for(int j = 1; j<=Runs; j++){
            if(suc[j-1] == k){
                distcount++;
            }     
        }
        bdist[k] = distcount;
        distcount = 0;
    }

    for(int t = 0; t<=btrials; t++){
        printf("Number of runs with %d 6s = %d\n", t, bdist[t]);
    }

    return 0;
