Star Wars only has six balls so no nine ball multiball. It does have a ton of different multiballs modes though. At least one, TIE Fighter multiball (three balls), is relatively easily achievable by kids. Overall a great game for kids even though it plays fast. My 4 and 6 year old love it and play regularly. And the theme doesn’t hurt.
Where are you located? If you tell us, there’s probably someone in Pinside that knows where you can go to try newer Sterns. That’s always the best way to judge.
