They had one at the local pub years ago Greg that I used to have a bash on . As a game I didn't mind it .In answer to your question about the drop targets YES you can hit them all with the flippers. Removing the white cue ball from the game I think will take away a big part of how it plays . The game needs the white ball to get the jackpots in multi-ball .You have to hit the cue ball up to hit the green targets near the base of the cue (these green targets are up high and can only be hit by the cue ball and not the pinball) . Once you hit the green targets the cue shoots the 8 ball at the coloured stand up targets in the raised playfield . Depending on which ones you hit as to what jackpot you get . If you take the white ball out how do you get the jackpots ... 

I like the look of the game and Clint Eastwood's voice is a nice touch .
