How They Work - Reflex unit
Almost all of the bingo machines have a reflex unit. Some of the mystic line games have two of them. The purpose of this unit is straightforward, it makes the game tighter after credits have been won.
If you are one of those happy/positive people, I guess we can say it makes the game more liberal if nobody has won anything for a while.
How it does this is very simple. As the game is racking up credits on the replay register, it is also stepping up the reflex unit. Wipers on the reflex unit rotate off contacts, thus breaking circuits.
As people play off credits or deposit coins, the reflex unit is stepped down, and eventually the wipers reconnect circuits.
Circuits
We're going to dissect a reflex unit from a bally big time - mainly because I had a parts head so I could rip the thing out and take it apart without worrying where I put all the pieces.If you've looked at some of the other sections in the "how they work" area, you are no doubt expecting to be bombarded with poorly explained circuit diagrams and incomprehensible tables of odds calculations. Since I'd hate to disappoint, here we go!

Mixer #1 is covered in another section of the site, but the executive summary is that the rotor on mixer #1 can stop in 1 of 24 positions. Depending on where it stopms, it may connect the green wire to one of the blue wires, or directly to the purple wire.
The reflex unit can be connecting the purple wire to any/all of the
wires entering into it on the left side. The more wires the reflex unit
is connecting, the better your chances are that the green wire will connect to
the purple wire.
