There's physical flow - which is what the flow-police are always after...relatively non-stop combos & balls feeding to flippers. Speed, really.

There's also logic flow. TSPP always gets shit for not being a flow game...but I submit that it is....every shot links to another meaningful shot organically. Sure, there are pauses - but pretty much every shot has a combo possibility. Example - you can shoot the ramp (back to flipper) then the Otto loop (pause, but feeds to upper flipper), shoot to Treehouse ramp (pause, pops to upper playfield), then shoot to TV (pause, feeds to upper right flip), then shoot up ramp to couch (pause and lock or start Multiball). So - less speed there, but still flow.

The thing about this is - every "flow" game has SOME stop. It just has to happen.

AC/DC=Jukebox saucer, Cannon, pops area, Bell (sorta)
Spider-Man=Doc Ock saucer/VUK, Sandman saucer/VUK, pops area.
Star Trek = Mode saucer, Vengeance Lock, Away Team shot

Even the beloved flow games have to stop the ball every so often.

I did that on purpose.

I explained why that's not true
