Is there any published information as to how slot fairness is assessed?

I had an unusual experience this evening. I opened a new account at Crazy Vegas, played the free play sign up bonus and racked up £100 GBP sign up bonus which you get credited after a minimum of £25 deposit. I did this - lost the deposit in the blink of an eye and about 30 mins later I got the 100 bonus. Played 2 slots simultaneously - Leagues of fortune and Immortal Romance. I have never played Leagues of Fortune before but it seems high variance and I was doing reasonably well on it. At the same time I opened up a simultaneous IR window and played that in the background on auto-spins to churn through the WR faster (I realise IR is probably not the best game for this). As I was playing I experienced a good run on LOF and the worst run I have ever experienced on IR. I have played IR many many times at a lot of casinos - I know it can be cold but I have never seen anything like this before. At the same time I was doing very well on the other slot such that my balance was not shifting much either way. After about 500 spins of IR in which I had one bonus round that paid next to nothing I closed down LOF and just stuck with IR as I felt that the poor run was due to end. It did not and the bonus quickly evaporated.

I understand that this can happen but I found it very unusual to see the game locked into such a bad run at the same time as an independent slot was throwing money at me. I know that the games are fair, because as we are always told, the games are monitored and assessed for fairness. This particular evening though has aroused my interest into exactly how this is done.

My question is this : Is there any information online that describes how this is actually performed and how many regulatory bodies are there (if more than one). Is the fairness performed on EVERY slot that a company such as MG or IGT produce or is the assessment performed purely on the RNG engine - which may be duplicated into the core of every slot. In such a case, are we allowed to know of the algorithms that do the RNG work? Is the source code itself checked or are the slots just run over a long time and the outcomes tested for randomness??

I realize I am asking a lot of specific questions here but what I am really looking for is a pointer of where to start when researching the answers. I know that a lot of the posters here and casino reps will know a lot about the industry, and maybe able to suggest where to start.
In the interests of transparency, it does not seem unreasonable to think that this information is available in the public domain. After all what use is a regulatory body if it cannot provide details of how it regulates the industry?
 
You're a maths man (boy :D ).

Surely you know the wild variations that can occur with such tiny sample sizes?

I would be more concerned if both games were right off the boil....although "more" than zero isn't much concern.

Its also interesting to note that, as per normal, the questioning comes as a result of a very POOR session, as opposed to a very GOOD session. Its incredibly rare for anyone to question fairness after a great run of big wins, so that should tell us something.

You're a smart guy. Work out your RTP for that session, and work out the odds of that occurring in that amount of spins. Its all about the maths :)

I'm absolutely not having a dig at you at all mate....just reminding you that maths and logic is behind it all.

Insofar as monitoring etc, all the legit operators have external auditors like PWC etc go over their game data to ensure all is as it should be.
 
Why dont you ask the casino for a link to their Ecogra RNG certificate for slots? Oh wait for some reason there is no certificate showing that Ecogra test the RNG on MG slots. There are however certificates for the RNG on table games. I'd also be interested to see any published information :)

I am not conspiracy theorizing here - honest!!

What you say about questioning after bad runs rather than good is spot on. I did not feel put out by this losing streak as it was all sign up bonus funds, it was just so unusual to see one slot payout out like crazy and the other drier than I have ever seen. The thing that got me thinking that had I observed the behaviour across just one slot it wouldnt have seemed unusual, then the fact that I was playing simultaneously made me wonder if perhaps ALL MG games share a single RNG and just treat the result differently per game to assess the payout off that number.

It just got me wondering how they DO analyse the slots. I will take a look at eCogra and see if I can get any info there.
