 Perhaps the two most common types of multiballs are *virtual-only* and *physical-only*. For *virtual-only* multiballs, you only need a `multiballs:` section to your config and a corresponding *start_event*. You do not need to configure a `multiball_locks:` section. Instead, a counter or *logic_block* is often used to track when the requirements for a multiball have been satisfied, such as a certain number of shots to the captive ball target in _Metallica_ for instance.
