I've played about 30 or so games on the Pro and I think the ring takes up too much space on the playfield and too much time during gameplay. I don't think there is any skill required in the ring playfield (at least compared to traditional flipper play) and it's quite boring and pointless. At least in the Pro, there aren't that many other interesting or fun shots to make. To me (and I'm certainly no expert at "flow"), this game has ZERO flow, due to how the ring playfield stops everything dead until the opponent is pinned or the ball falls out of the ring and makes it back to the main playfield. I think the pin would have been better if they used drop targets and actual flippers in the ring mini-playfield (maybe similar to Big Guns?) or if they made the ring smaller and not such a big part of the game.

Unless I'm missing something, what other shots or flow does this game have? You can shoot the inner horseshoe-shot/lane but that's pretty uninspiring, and the only real combo shot I can think of is hitting that horseshoe shot and then hitting one of the outer ramps to shoot the ball up into the ring mini-playfield where you'll Doink the ball around until you pin your opponent (which could last minutes) or the ball drains back onto the main playfield.

The art, sounds and dots are OK, but the game just isn't fun.
