I've played a Border Beauty, a Zodiac (with no backglass) and a Double-Up. Out of those three, I like Double-Up the best since you can win up to 2400 replays on a single game!

The player-controlled score doubling/quadrupling feature is really a thinker - the only downside is that you have to make your choice before the 2nd or 3rd ball.

Hawaii adds the stop n shop from Cypress Gardens, but not really worth it in my opinion.

I think the best games, though, are the combo solid state/EM games. You have multiple options of what to shoot for, and you're not totally screwed if you hit in the star zones when they're not lit, since you've got a separate game playing out on the side.

I've never played a real one of those, but from the features, I think London, Safari or Super 7 would be the best choices.

Many of the other mystic lines games are very similar with randomly awarded score doubling or tripling.

It's really satisfying to hit all four star zones for 300/600 on Double-Up.

I also find that with the Mystic Lines layout on Double-Up, that getting my red letter game is easier than on a Magic Screen game.

I always was attracted to the Safari artwork and game play. If I had the space this would be my first choice for a 20 hole mystic bingo.

I've heard Safari is the one too Vic.

Although I remember hearing about a bug in them.
The bug had something to do with shaking the game at the right time and running the animal ladder all the way up ... think that what I recall anyway.

Might be discussed in that "Top Secret Underground Bingo Video" I sent you a few years ago ... Guess I'll put it on to keep me company next time I'm working on '56 Derby Day and see.
