Setting bingos on free play is actually relatively straightforward - there are really only two major differences during the entire Bally run.
One thing I believe I forgot to fully flesh out:
The 'anti-cheat' switch that I reference is also known as the anti free-play switch, and is located on the left (or numerically high) side of the replay register.
How do you put your wedgehead into free play? I have a few suggestions.
My main recommendation does not require an additional switch, however, there are several ways, depending on the era and type of circuit used to count coin drops.
A few are listed here!
Chad is a fellow EM collector with a Bally Beach Club bingo in his collection. After experiencing the bingo row, he is now looking for another great bingo game for his collection.
He is a heck of a nice guy, with a love for the mechanical aspects of these fantastic machines. I hope he's playing a new bingo soon!
Bally's Yacht Club used a mechanism that was not used in any other bingo!
The numbers on the backbox are arranged in a 9x5 grid. By default, the second through the sixth column of numbers are surrounded by a yellow border. This is the card you are playing for.
If you earn the feature, you can move those yellow lines to surround a different set of 5x5 numbers! This changes the makeup of each row as you move the surrounds.
In my mind this is the precursor to the Magic Screen - just less expensive!
It was likely confusing for new players, which may have been why it was never used again.
Run down of the items that had issues before/at York in Bounty and how I plan to correct. Disassembly and reassembly of magic screen, lubricating clutches, checking all steppers and re-cleaning them. Replay register tear down, clean and rebuild, and more.
Basically, finishing the rest of the shop job that I started on this game when I got it.
In 1962, the Magic Screen games were kings of bingo production. During this time, Bally experimented with a new way to use the same mechanism - instead of sections that allow for different scoring, what if the player could control the makeup of the bingo card, one column at a time.
Seemingly a natural evolution to the typical ways that a player can control the makeup of their cards, this method was never repeated by Bally.
A single button game, another unusual feature of "The Twist" was that the player was notified what their next coin would do: advance one of the sets of odds or advance the 'magic cards' feature.
Another game I'd love to play one day.
Magic Screen Units, when misaligned, exhibit certain symptoms which will help you diagnose (and correct) the problem.
Exhibit's Mystery is a beautiful sequence game. A masquerade theme, with mystery kick out awards.
Complete sequences 1-4, 5-8 and 9-12 to light three different playfield specials.
Gorgeous backglass and playfield artwork with fantastic lightboard design and a great stencil round out the package.
Magic Squares units are a really neat moving numbers feature.
After working on a few games with this feature, I really appreciate their simplicity in design.
