County Fair

County Fair introduced what is probably the most popular feature on all of the bingo machines - the OK/Red Letter Game.

On orange section on the Magic Screen could be moved across some of the numbers when the OK feature was lit. If you get at least two numbers lit in the orange, then you can get a free game that has guaranteed minumum odds and features lit. Usually the odds/features are better than the current game you are playing, but not necessarily.

The starting values for scores/features on the free game were displayed on a S/I card mounted on the bottom of the playfield, so you knew what would happen ahead of time. The levels corresponded which letter was lit in red in the game name - hence "red letter game".

What most players didn't know was the red letter was directly tied to the green score odds level. If you green odds were low, and your red/yellow odds much higher, shooting for the OK game was probably not the best idea.

To get an idea of the OK game levels, look at the award cards for this game and the next few screen games.

First introduced in Carnival Queen, the numbers on the card are stationary, but a moving metal screen is slid across them.

The screen has in-line scoring and irregularly shaped colored section scoring. In the sections, rather than needing 3,4,or 5-in-line, you can get 3,4, or 5-in-section to score. While some sections have numbers that are in a line, to win in a section, the lit numbers DO NOT need to be adjacent!

Screen Home Position Screen Position B Screen Position E Screen Position G

In the screen home position, the standard three color in-line scoring is available. As the screen is slid left, the in-line scoring is replaced with section scoring. At position B, the scoring is a combination of both methods. By position E, in-line scoring is gone completely.

Also notice how in position B, the green diagonal is now over three numbers that could not be a diagonal winner on the screen in the home position, but only three numbers are in the diagonal line!
