Is each reel of a slot machine independent?

Hi everyone, first time poster here.

My question is, is it a requirement for class III slots that each reel be independent?

I understand that each reel may be weighted, but is it a requirement that the probability of a certain landing spot on reel 3 be independent of the landing spots on reels 1 and 2?

Or is it (for example) allowed to have reel 3 more likely to land a jackpot symbol when reels 1 and/or 2 don't have that symbol showing (to create more "near-miss" results)?

If it matters, I'm talking about a 9-line machine with physical reels.

Thanks

No. The RNG picks a number which maps to a reel setting.

This is my suspicion as well. This means that “reel mapping” is basically useless. I have played some of the 5 and 9 line slots where you try to line up wild wild wild on a payline. I know one in particular that probably every 10 spins the first 2 reels always give you a wild then the machine goes into that slow whiney mode where it builds suspense that the third reel may be a wild. Then it literally blanks every time, missing by one place on the reel. It happened so often it was almost a joke cause you didn’t even want 2 wilds cause it always blanked. So if you get wild wild it’s basically at least 50% chance you will get a symbol on the payline. But this would happen over 20 and 30 times and nothing. Maybe once or twice a bar symbol would land but never a wild or 7. So basically all 3 are synched together to produce a result

I think there was at one point, at least in Nevada, but I have copies of the gaming regulations going back to 2007 and cannot find such a requirement since then.

The question is, do "reels" actually exist any more, or does the machine (assuming it's a video one, of course) have some method of generating the displayed symbols on its own - for example, to increase the number of "near misses"? That is, each number in the range of the RNG does not correspond to a specific pattern of displayed symbols, but only to a result, and if it is a losing result, the machine can display a losing pattern of symbols in any way that it can.

In most Class 3 jurisdictions each reel must be independent and can not be influenced by other reels.
