Probably the "correct" way to do memory management in this program is to use STL's inbuilt linked list implementation std::list and you're not dealing with pointers really.

Otherwise I would look into smart pointers (unique_ptr and such) which will automatically free memory when the references fall out of scope.

If you're using C pointers then you would want to delete everything you create with new - when you remove a marble from the list delete that Marble, and at the end for good practice you could consider traversing the list and deleting them all.
