C++ Palindrome Help

Question

I am doing the c++ course and i am stuck at the Palindrome numbers challenge.

for some reason my code works for the visible test cases but fails for a hidden test case.

Can anybody please tell me why :) ?

#include <iostream>
using namespace std;

bool isPalindrome(int x) {

int num;
int rev;
int dig;
num = x;
dig = num % 10;
num = num / 10;
rev = rev * 10 + dig;

if(num!=0){
isPalindrome(num);
}
else{
if(rev == x){
return true;
}
else{
return false;
}
}

}

int main() {
int n;
cin >>n;

if(isPalindrome(n)) {
cout <<n<<" is a palindrome";
}
else {
cout <<n<<" is NOT a palindrome";
}
return 0;
}
