I own a Daffie. It's different from Doozie in that it has one less pop bumper, replacing it with a drop target worth 5000 points. This target stays dropped once hit, until the end of that ball, then resets with the next ball, and it's always worth going for. Trying to get 1-2-3-4-5 over and over is not a dull thing here, with the ball whipping around the playfield where five numbered rollover buttons are almost a happy surprise each time you get one, which is frequently. Completing the sequence advances the X. The operator options allows several different configurations of lighting the 4 Specials depending on which X you have achieved, including no Specials for any/some X's, so I made me a little matrix of all of the options and which specials they would light for each of the eight X's, then chose the configuration that I thought gave me the best fun and motivation throughout the game. So, the Daffie you encounter may have a different Specials configuration which may affect how you feel about the game. I was actually looking for a Doozie when this Daffie came along instead so I bought it and have been quite happy with it. One of the few add-a-balls in my collection. It's a keeper.
