TL;DR

EM slot machine deep dive: Mills vs Bally designs, mechanisms, and trade stimulator variants

Summary

Nick Baldridge explores electromechanical and mechanical slot machines, comparing manufacturers Mills and Bally, their distinctive designs, and mechanical/electromechanical features. He discusses trade stimulator add-ons like vending and future pay options, the mechanics of reel stopping and payout systems, and references an interview with Phil Hooper about the Bingo Continental slot machine.

Key Claims

Mills slot machines typically featured molded cast metal frontispieces depicting medieval castles, eagles, or arrows; Bally machines were flatter with fewer ornamentations
high confidence · Nick Baldridge, direct comparison statement in episode
In the UK, slot machines are called fruit machines because most reels display fruit images (cherries, oranges, plums) and winning combinations require three in a row, except cherries which can win with two
high confidence · Nick Baldridge, established gaming terminology explanation
Mills manufactured a trade stimulator add-on called the future pay option that required inserting an additional nickel to receive payout from a previous winning combination
high confidence · Nick Baldridge, described from video documentation
Mills purely mechanical slot machines use springs, levers, and a timer mechanism (fan on shaft) that latches into reels to stop them one at a time
high confidence · Nick Baldridge, technical mechanism explanation
Bally electromechanical slots use phenolic rectangular discs (not circular) that make contacts to identify winning combinations, similar to bingo machines
high confidence · Nick Baldridge, technical comparison with bingo mechanisms
Phil Hooper discussed a Bally slot machine called Bingo Continental that featured bingo-style gameplay with advancing odds and payouts
high confidence · Nick Baldridge reference to his own interview with Phil Hooper
Mills slot machines displayed the hopper full of nickels or pennies as an enticement to win the jackpot
high confidence · Nick Baldridge, design feature description
Bally slot machines were more complex and feature-rich than Mills mechanical equivalents because they had electrical systems
high confidence · Nick Baldridge, comparative statement

Notable Quotes

“I am absolutely no expert on slot machines i have helped some friends fix a couple of them but i don't know a whole lot about them”
Nick Baldridge @ Opening — Establishes disclaimer and framing for the episode's scope and limitations
“Mills slot machines are fairly distinctive. They typically had a beautiful, molded, cast metal frontispiece that looked like a medieval castle or an eagle or an arrow or something like that.”
Nick Baldridge @ Early segment — Establishes key visual distinction between major slot manufacturers
“in the UK, they call these fruit machines, and that's because most of the real pictures are images of fruit. cherries, oranges, plums, and so forth.”
Nick Baldridge @ Mid segment — Introduces regional terminology and game mechanics (three-of-a-kind, cherry exception)
“The purely mechanical slot machines are creatures that are filled with springs. And when you pull the arm down on the right-hand side, it allows for some levers to disengage and a timer, which is basically a fan on a shaft.”
Nick Baldridge @ Technical explanation segment — Core mechanical description of Mills slot machine operation
“I find the Mills slot machines pretty fascinating... but the Bally slot machines actually had a lot more features because they could be more complex since they had electricity.”
Nick Baldridge @ Comparative analysis — Explains why Bally electromechanical systems enabled greater feature complexity

what's that sound it's for amusement only the em and bingo pinball podcast welcome back to for amusement only this is Nicholas Baldridge today's topic is em slot machines and i am absolutely no expert on slot machines i have helped some friends fix a couple of them but i don't know a whole lot about them So I'm going to preface this episode with that disclaimer. I do know that two of the prominent manufacturers of EM slot machines were Mills, who had been manufacturing slot machines for a very long time, and Bally. Now Mills slot machines are fairly distinctive. They typically had a beautiful, molded, cast metal frontispiece that looked like a medieval castle or an eagle or an arrow or something like that. Bally's were typically flatter and had a graphic or two, but a lot fewer ornamentations. So slot machines are mechanical devices, typically. Some of the bally's are electromechanical. And when you put in a nickel or a penny into a mills slot machine and pull the lever, it will advance the nickel in a visible window that shows you how many nickels have gone in. It's just a kind of cool little backbox animation. the mill slot machines also have a visible window that shows the hopper full of nickels or pennies And this is an enticement for you to win the jackpot, basically. But in the UK, they call these fruit machines, and that's because most of the real pictures are images of fruit. cherries, oranges, plums, and so forth. The idea is that you get three in a row, and that gives you a winner. Cherries are the exception. You can win typically with two instead of having three in a row. So in the mills world, they also manufactured trade stimulators, as I mentioned. in a previous episode. Well, their slot machine division was also interested in selling these slot machines to bar owners and the like in territories where gambling was no longer permitted. And so they started making these trade stimulator style add-ons, one of which would be a vending add-on that you would clip onto the machine. And when you put in your nickel, it would not only activate the mechanism for the slot machine, but it would also vend you a roll of mints or candies or something of that nature. Beyond that, there's another add-on, which I've only seen in video form, and that is a future pay option. what this does is it requires you to put in another nickel in order to receive your payout from the previous winning. So when you put in your nickel the first time, there's a window up top that shows zero. If you get a winning combination, that number will change to whatever your payout's going to be. And then when you put in your next nickel, you actually get the payout. this is completely different from the typical payout style of a slot machine which is instantaneous at least in the EM slot So this future pay option had an actual physical display Again, it's beautiful, molded metal. And it says, before you make a purchase through this vendor, look in the window and see what you can buy for your coin. your coin buys a package of confections and window with amount of winnings amusement tokens. Now these amusement tokens could have been something other than nickels but you're only putting nickels into the machine so yeah I'm not sure if you could separate the payout hopper or if someone would have to very quickly change out nickels for tokens in order to make this work. But the purely mechanical slot machines are creatures that are filled with springs. And when you pull the arm down on the right-hand side, it allows for some levers to disengage and a timer, which is basically a fan on a shaft. And as it rotates, it's going to latch in to the reels and stop them one at a time. when it's finished the last lock-in, the machine will look at what you've got and pay you. And it does this in a very similar fashion to the way a bingo or other pinball might do so. It knows which images are shown to you through a search style mechanism. Now, the bally slots are incredibly similar to a bingo in that they have phenolic discs They not actually circular They rectangular But as the reels stop these phenolic disks contacts are made in such a way that it knows you seeing a bar you seeing a cherry whatever And when you have a winner across all three, you get a payout. Now, those Bally electromechanical slots have coils and hoppers and so forth that activate based on the activity in the machine. The Mills ones, being purely mechanical, don't have that luxury. And for this reason, I find the Mills slot machines pretty fascinating. but the Bally slot machines actually had a lot more features because they could be more complex since they had electricity. And so Phil Hooper, in my interview with him, talked about one such Bally slot machine. This slot machine is the Bingo Continental, and it had a bingo-style game with advancing odds and would pay out. Pretty intriguing stuff. At some point, I may get more into slot machine repair, but it's relatively simple. I say relatively as the operative word, compared to the pins that I prefer to work on. Well, thank you very much.
