Virtual reels to physical mapping on multi payline machines (IGT S+/S2000)

[AceStrategist]

As the title says, how do the virtual reels function when multiple paylines are in use?  For example on a single payline machine the virtual reels could contain any symbols the physical reel has, jumbled in any order and the mapping of virtual to physical is only a matter of spinning until the virtual symbol is hit on the physical reel since what's above or below the payline doesn't matter. 
What happens when multiple paylines are in use like triple top, middle, bottom, 9 lines or 20 lines in the later S2000 machines?  A virtual reel could contain combinations of symbols like a cherry immediately followed by a triple-bar that don't exist on the physical reel: all cherries are followed by a single or double-bar.
Even if instead of a large virtual reel the developers used the physical reel with 'weights' on each symbol you could run into a situation where the jackpot symbols happen to be followed by cherries and single-bars (which have a comparatively much higher chance of coming up), leading to the situation where they pop up on the middle payline frequently causing the upper payline to hit jackpots at too high a rate.

I'm not sure if that's how an RNG works?

The virtual stops increase the non winning combinations .  They did this to produce higher jackpots, which means less frequent winning combinations. 
The following video gives an idea. 
As for multi line machines, some reels have fewer symbols, usually reel 3.

Another one to watch

Those links redirect to: "Constant Contact Marketing Tech Level Up" and "Square: Premium Plus Membership" which don't have anything to do with slot machines?

That's weird.  I copied the video links. I'll see if I can find them. Thanks for pointing that out.

Here is an article about it also

Trying the link again.  The way they made the YouTube video,  if you linked it, the sponsor video would play, and not the intended video.


I tested this one.  Works for now. Has an ad that can be skipped.
Thanks,

Good video mopar!
Watching that video, it really makes me think of how they "weigh" the virtual stops....making certain stops "more  frequent" rather than "random".
Also, that video was primarily made for a single payline.
I think we need to try to find him some information of how they weighed symbol stops with multi-payline games.
