Thanks for the article, I tried to read it carefully, but it seemed difficult to understand.
The explanation is certainly very complex and very foreign to me.
I'm terms of manipulation, well I wouldn't call it that. I'll say house edge because it has to be set in such a way that the operators has more wins so as not to go bankrupt. No manipulation just some mechanical settings.
And yes, the term I should be using, because every casino is looking to profit from the machines they provide for gambling.
If it only benefits the player, then the casino will go bankrupt.

I hope we can find details on how the random algorithm works on vintage slot machines or how it follows a random result.
You can read the article given by @Davidvistorson, there has been explained how slot machines work.
Whether or not you are playing on a machine that might be tight or loose would likely depend on whether the machine you are playing on is in a legal jurisdiction or not. Illegal operators would probably set the machine for the highest house setting whereas legal establishments probably have to abide by some sort of regulation.
Never played such or any other antique slot machine because in my country alone there are no such machines, no gambling establishments.
With regard to legal jurisdictions as well as some audits conducted on slot machines,
whether, slot games available at online casinos must also comply with legal jurisdictions and conduct audits before being given to players.
Since many online casinos are illegal and do not have any licenses,
I found many casino advertisements that promise huge profits with slot gambling.
