Slot Mechanics (Was: Fruit Frenzy Game glitch or frenzy?)

Good answers:thumbsup:

These questions have been discussed and theorised for some time. I now have another follow-on question.

If the RTP component for the Random Jackpots cannot exceed 1.5, how does this fit with what players have reported seeing at Rushmore, which is also RTG.

Here, the Random Jackpots fly far, far, higher than at any RTG casino, and rise faster.

Rising faster can simply be explained by more money being played through the machine than at other RTG casinos, but there are two other points.

Given that:-




How can the Rushmore jackpots survive more "standard trigger chances" before being won than at any other RTG casino? This contradicts what has so far been explained about how Random Jackpots, RTP contributions, and standard trigger chances work.

On top of this, there is the matter of them being won, and then reappearing at $5000 reset value, not $1000. Whatever proportion of RTP contributes towards the reset, Rushmore are using 5x. If individual operators cannot alter these RTP components, what is going on here with this REPUTABLE RTG casino. They seem to have software options that have not been seen in use at any other RTG.

My guess would be that they link more slots together for the RJ than some other RTG's
I think the Casino has the option of how many slots to link for a RJ.
If this is correct it would also give the illusion of them being won less often and explain why they go up so quickly.
Dogboy over to you.

Yup, that is correct.

I neglected that RTG introduced an option for multi slot contribution to the random jackpots, with a $5000 reset and proportional adjustment to trigger chances. Total contribution is still less than 1.5% of total RTP in these instances.

If individual operators cannot alter these RTP components, what is going on here with this REPUTABLE RTG casino. They seem to have software options that have not been seen in use at any other RTG.

As with RTP settings (95 versus 97.5), this is something that operators can select to implement.
Throw into that list maximum bet (the Crystal group would allow up to $1000 bets, most others select $100, and Crystal also used the $5000 RJ resets)

Other than these parameters there aren't any aspects of gameplay that an operator has a selectable option over.

I just wanted to extend my welcome to you, Dogboy001 and a thank you for your informative posts! Very interesting reading.

Hi dogboy,[

100 spinds with no Ronin symbols in view?
On all reels?
I gather this is in real money mode?
And happens on all casinos? (I ask this last one not due to any operator ability to set game play attributes, but in response to the quote about first year profit.)
And only seems to occur on Ronin?



I am giving Ronin as an example but this effect is by no means confined to the Ronin game or even RTG software and no not all reels just reel One although the other scatters will appear much less frequently and this will always occur after arun of features or one very good payout from a feature.
Yes real money mode :D though we are led to believe this one and the same as play money mode.
Another example different game different software would be MG's Halloweenies where the scatter symbols appear with great frequency on reels 4 and 5 and yet mysteriously appear very rarely when scatters are hit on reel One an Two.
The new Rival slot Jaquespott, same thing scatters every other spin on reels four and five but out of maybe 40 times of hitting the first two sctters I did not manage to trigger the feature once. Statistically about as likely as winning the lottery twice in a row.

On Ronin this has occured at probably every RTG casino I have played at and that maybe every RTG casino except the named rogues.

The games are designed as any normal land-based slot.
They have a fixed (by that I mean static and not dynamic per spin) reel strip (which we often improve during feature sequences) and definitely is not using pre-determined features (canned results).
Casinos often lose on several of the slots in any given month, which would be impossible if it was a pre-determined scenario.


It has been proven that many so called random features do indeed have canned results as you put it.
Bonus rounds for example being added to the balance before being started/completed.No reson to think free spin rounds are any different.
There are various threads here on the matter though granted much of the evidence is circumstantial.
That said even you admit that these rounds are manipulated at least a little sometimes so it is not a large step from there to my position.

Landbased video slot reelstrips most certainly are dynamic!
They add and take away bonus symbols all the time.
I hve played RTG games to death and can tell you exactly where a symbol will satop on the "longspin" (2 scatter symbols already in view) as soon as it starts the problem is the animation jumps and resets change things.
When an RTG slot is playing badly these resets are common and the feature never hits when they occur.
There should be no need for the reel animation position to be reset.
As an experiment I played at Two RTG casinos (same slot achilles) simultaneously.One Casino was "hot" and the other I had never had better than 70% RTP. The Casinos were Bodog and clubworld or inet I forget which.
At Bodog there were no reel sets and the animations were smooth at the other Casino the resets were frequent.Also the frequency of the more favourable symbols was greatly reduced at the second casino.
The connection at both casinos was excellent.

Actually, you'd be amazed at what would pass UK legislation
We have our games in numerous Talarius establishments in the UK (and soon to be with a few other groups).
There are several games out there from our competitors that flout the law entirely in regards to bet and win parameters on single games (beyond their stated ability to link several rounds), but the UK legislators a) do not care and b) do not have an enforcement ability at this time.

I'm sure casinos would love to be able to guarantee first year profit (or profit in any year for that matter!), but other than having an edge via RTP settings all I can say is that there is no turn-off switch.


I am quite well up on the gambling commissions requirements for gaming software to be licensed in the UK and hence everyone plonks their servers far far away although I understand there are obviously other incentives.
That is the reason they do not have enforcement ability.
Instead we have wonderful regulatory bodies like ecogra and licensing territories such as Kahnawake and costa rica, Belize and Antigua.

According to that philosophy we'd never be able to sell a game anywhere
We give our buyers some (and in many caes no) level of input into many aspects of the game design process.
The buyer does not always know best.

RTP is determined at the software level.
I'm sure Warren would have loved the ability to adjust things himself when he was around, but that just ain't the case.
I've been telling my parents for 20 years that operators at their local clubs cannot just switch a machine, that's it's just not in the code...still can't convince them so I doubt I'll have much success here, but the same applies.


I was not suggesting that operators have an input or would want any input into game design, leave it to the experts.
I was suggesting that a potential operator (customer) might want their slots set at 90% and you are saying that providers simply tell them to take their business elsewhere because they only provide 93%,95% and 97%.
I can't believe that, sorry.
As VWM asks what is the mechanism that alters payout% anyway if it is not through altering the paytable?

The "switch on a machine" certainly exists in AWP games, that is hardly a revelation and yes you are right you will never convince me (until properly licensed) that online slots are completely random and each result is completely independent from all previous results.
By the way for fun I made Two versions of the same 5 line video slot and made One completely random and put a subtle dynamic weighting system in the other.
The people who have tried them so far can not tell them apart (sounds like an advert for catfood :D ) so it is not hard to implement if the will is there.
Are casino operators hungry for guaranteed greater profits?

I doubt I will convince you either but hey ho I will give it a go :thumbsup:
 
I have just realised we have hijacked fleur de lis's thread. Sorry.
Maybe as you are a new member Dogboy and say you have experience in RTG slot design some of these later posts should be moved?
Bryan?

This explains alot!

If the trigger chance was lowered as well as slots being linked, then indeed we would see exactly what players are reporting at Rushmore, rapid increase to very high RJ values before they are hit. This would not need any further RTP contribution than the stated 1.5

I think the other question has been answered, the change between 95% and 97.5% is achieved by small changes to the reel strips, such as substituting a low paying symbol for a wild, thus increasing payouts. Since RTG software handles this during bonus rounds as a matter of routine, it is no problem to have the same code create different payout versions of the base game, and have a selection list, currently said to be 3 variants of each slot.

The argument is of course that this appears to happen in game hence the resets and glitches.

Heya,

Depending on the game in question, reel 1 would usually see a scatter appearing every 10 to 15 games, on average (some games have many more than 45 symbols on the reel strip though, so some will be a lot higher).
Mind you, statistically you will get runs without this occurring, even with a 1 in 10 chance.


Yes real money mode :D though we are led to believe this one and the same as play money mode.

The difference between real money and fun play has nothing to do with the RNG or game math, but in many instances you'll find that system providers do not generate or store results on the same servers for fun versus real play modes.


It has been proven that many so called random features do indeed have canned results as you put it.
Bonus rounds for example being added to the balance before being started/completed.No reson to think free spin rounds are any different.
There are various threads here on the matter though granted much of the evidence is circumstantial.

Ahhh...now I see where some of the conspiracy theories have come from!
Results being added to the balance before the completion of the bonus rounds actually sprang from a communication process rather than being something that was not random results.
Results for the entire free game sequence were being requested at the start of the feature triggering.
i.e.: A trigger event occurs (let's say 3 scatters), this being a random process whereby the RNG is pinged 5 times to determine reel stop positions and then a win evaluation routine would run to see whether a win had occurred. In this case it would say: "Oh look, I've triggered 15 free games, please give me the result of those 15 games."
The RNG would then spit out free game 1-15 results (each of which follows the same process of RNG pinging, determine reel stop position, evaluate win)..and indeed if it determined that over the course of these 15 spins a re-trigger occurred, then it would say: "Cool, give me the other 15 results too" and so forth.
What that means, of course, is that it's possible that if a comm error occurs in some cases it's going to flick the entire win sequence to the balance meter (this was more prevelent in the past than the present).
All the results are, however, still randomly determined and evaluated from that basis.

Indeed when the games first came out you may have noticed a huge delay when a trigger was going to occur, because it was requesting all results during that time...didn't do much for anticipation!

That said even you admit that these rounds are manipulated at least a little sometimes so it is not a large step from there to my position.

Though always to the player's advantage :thumbsup:


Landbased video slot reelstrips most certainly are dynamic!
They add and take away bonus symbols all the time.

Well I can only talk about the groups we have or do provide games for, or that I've worked for directly, which would make it IGT, WMS, Bally, Atronic and a host of smaller groups.

Out of these only one used a dynamic reel strip of the manner you're talking about, and phased that out years ago.
A dynamic strip is one where a single probability table is used to determine what will come up in any given symbol position (eg: 2% for substitute, 2% for scatter, 5% for symbol 3, 6% for symbol 4 etc)
It would then calculate what it would need to display in any given location (so it would ping 3 results for each reel and display the appropriate).
In other words, sometimes on these type of games you might get all 15 symbols apppearing as a substitute.

There is another type, which is commonly known as Class II games (in the US only). These are actually bingo games that use a slot display mechanism.
The calculation is done as a bingo product, and then the slot is used to display a win that corresponds to the required win.
e.g.: In the bingo game a win occurs and a prize of 5 is required.
The slot then displays, say, 3 Lemons, that correspond to this prize.

In no way is this how on-line slots work with RTG.

I hve played RTG games to death and can tell you exactly where a symbol will satop on the "longspin" (2 scatter symbols already in view) as soon as it starts the problem is the animation jumps and resets change things.
When an RTG slot is playing badly these resets are common and the feature never hits when they occur.
There should be no need for the reel animation position to be reset.
As an experiment I played at Two RTG casinos (same slot achilles) simultaneously.One Casino was "hot" and the other I had never had better than 70% RTP. The Casinos were Bodog and clubworld or inet I forget which.
At Bodog there were no reel sets and the animations were smooth at the other Casino the resets were frequent.Also the frequency of the more favourable symbols was greatly reduced at the second casino.
The connection at both casinos was excellent.

Sorry, but this is another one I'm adding to the urban slot myth category :rolleyes:
The anticipation reel spin does not ping the server again and ask for a stop position at the time...especially a new stop position! Boy, if slots worked by only spinning one reel at a time, then waiting for a server result for the next reel it'd take 10 seconds just for one game to occur.

Animated reel strip "resets" occur in all video games.
Again, nothing sinister, and I'll draw on land-based video as an example (though the net is exactly the same):
When a video reel strip starts to spin it has a known start position (let's say, symbol stop 17 is the start (middle vertical) position, on say a 45 long reel strip).
The RNG has said: "Stop on position 10 this spin"
What will happen is that the start position will determine what you see when the reels take off and start spinning.
At some point during that spin the game knows that it has to finish on position 10. Since we have a fixed length of time on each spin, at some mid point it stops showing the reels spinning from their start position and jumps to show the reels leading up to the position it will need to stop on.

It's almost impossible to notice, unless of course there's an extended anticipation spin going on.
Other reasons it could become noticible may be a lack of seemless transition between start and stop position strips (so in a seemless environment it would seem to be a natural spin, but if there's even a fraction of a delay it can look like a symbol arbitrarily changes).

Either way, however, there's nothing rigged about it. It's just trying to display the result the RNG has determined.

I am quite well up on the gambling commissions requirements for gaming software to be licensed in the UK and hence everyone plonks their servers far far away although I understand there are obviously other incentives.
That is the reason they do not have enforcement ability

Actually I was talking about physical product in the UK market :thumbsup:

I can't believe that, sorry.
As VWM asks what is the mechanism that alters payout% anyway if it is not through altering the paytable?

Well it's the case, since we produce all the mathematics I'm pretty darned sure what's available.

The mechanism is one of the 3 items I posted earlier.
Most typically a simple symbol change (e.g.: changing an A to a substitute on reel 4, for instance), is more than enough to give several percent difference to the game RTP.
Other changes I noted were making additional reel strip alterations during a feature only, or adjusting pick feature probability schedules.

The "switch on a machine" certainly exists in AWP games, that is hardly a revelation and yes you are right you will never convince me (until properly licensed) that online slots are completely random and each result is completely independent from all previous results.
By the way for fun I made Two versions of the same 5 line video slot and made One completely random and put a subtle dynamic weighting system in the other.

I doubt I will convince you either but hey ho I will give it a go :thumbsup:

It's always interesting hearing people's points of view, and yep, think we'll have to beg to differ on the matter.
And yet, how can an operator make a loss on any given slot in any given month if it's dynamic in the way an AWP is?
And yes, I can't remember seeing a report that has all slot games all positive for a short period like a month...and no, I'm not allowed to show them :eek2:

But one of us is right, and one of us in wrong :thumbsup:

Cheers!

All I can say is, things are going to get even better over the next year or two...some very exciting stuff on the way :thumbsup:

By this time next year these will also be physical machines in my home state with one of our land-based clients...I'll finally get to play them other than on-line.

The maths, by the way, are the same in essence...only the RTP's for land-based play are hideously low (85% being typical in most pubs and clubs in NSW)

I would also like to warmly welcome DogBoy to the forum :notworthy

I haven't had time to read every bit of every post yet, but there some really interesting stuff in there, most of which I had already assumed (being a pro 'slots are random' advocate :cool:)

I hope you stick around a long time and share more of your great knowledge!

So that was why the long pause on Cleopatra when you knew free-spins were coming! I hated that! :mad:

You are being spoiled, for Fruit Machines here it is 70% to 78%, with most being at the lower end.
We do have some video slots now, 1 per spin and 500 top prize, with RTP of 92% (these are more likely to be similar to the 85% "pokies" you have, so in this respect, we are doing better with 92%:p)


As for the slot returns that you "cannot show", this again is what makes players edgy. Why hide good news? Microgaming casinos have independently audited payout summaries done for each month, and even though the original auditors pulled out, they have engaged a new firm.
There should be no problem publishing actual slot results for interested players to look at, indeed, they would refute many of the claims that casinos have "pulled the kill switch this month". Most of these claims have been leveled at RTG and Microgaming casinos. With Microgaming casinos though, the audited figures will eventually appear, and show that over the long term the RTP was still running at around the 95% mark.

RTG casinos MIGHT have something to hide though, and that would be whether they have elected to use the 95%, 97.5%, or 93% RTP option within RTG software. The figures being published would make which option they have chosen pretty clear, and would allow players to make an informed choice as to which RTG casino gets their custom.
 
there's alot of reading on this thread to be done... I'm not gonna do it! I am bored with details!!! Just win..ok? And let us know when you do! Otherwise..nobody really cares!

Landbased video slot reelstrips most certainly are dynamic!

Heya,

As I was galavanting at baseball today I realised that I may have misunderstood what you mean by "dynamic reel strips".

While my definition of dynamic strips is what I've previously described I think you may be referring to "dynamic reel strip stop locations", which are certainly used in some land-based machines, almost exclusively those that are known as "steppers", or the older mechanical gaming devices that have physical reels (as compared to video).

In these games there's certainly a weighted component, with an uneven chance of landing on a particular stop location (e.g.: Stop position 1 might have a 0.1% chance of coming in on reel 1 as compared to 5% for stop location 2, 1% for stop location 3 etc).
So if a given mechanical device reel is say 30 physical symbols long, it will not be 30 even chances of landing on each stop location.

Not all steppers use this function, but quite a few do.

For most jurisdictions it's required that video reels use even distribution when determining a stop location.
This is also how RTG's product works, as well as I dare say the majority of other reputable system providers.

Apologies for any confusion with my terminology! :)

Thanks for the welcome, glad I can contribute!

I can't divulge exact game info to the level of giving out the physical layout of the reel strips...that would invite duplication by other system providers, but I can hopefully provide more general insights into a few aspects of the games and system.

Yup, was 2 per spin until recently, 500 top prize, changed a little while ago to the 1.
We've got a bunch out there, including Aztecs, Cleo, Goldbeard and Caesars, with Talarius (I think they're still branded as the Quicksilver shops, but were bought out by Tattersals recently so not sure if there's any re-branding going on)
We do 2 bet, 4000 top prize variants for the UK casinos too, and even 50p bet, 35 for the Cat C market (mind you, will shift to 50 very soon...you heard it here first...ish :rolleyes:)

AWPs will have a UK market for a long time to come, but the more random slots that get out there the better I say.

The figures being published would make which option they have chosen pretty clear, and would allow players to make an informed choice as to which RTG casino gets their custom.

What extent do the publication of the MG figures go to?
Is it a straight percentage breakdown summary that indicates total RTP for each game, is it on a casino basis, are there turnover figures?

I've made RTG aware that I was posting to the forums here, since I felt there was a need to clear up some miscomprehensions.
The other reason is that we deal with a lot of land-based markets and land-based groups...our reputation is on the line too, so it's important to realise that a fair system is highly important to RTG.
Even within the last few months we have elected to maintain and strengthen our association with RTG, over advances from 3 of the other majors, because we believe we can help make the RTG system and game library the best out there.

I can't promise anything (and let me stress that, since I hate to let people down, and since there's very good commercial reasons not to divulge turnover figures, and contractual obligations that may prevent any disclosure), but I will discuss the issue of providing summary percentage figures with RTG's head.
If they did agree it might only be on an annual basis at time of audit (and yes, they do undergo stringent processes in this manner)...but I agree that even that would be worthwhile to reinforce the fact that this is a truly random system.
If they cannot provide a breakdown of this type please don't read conspiracy into it! :cool:

Why would you want to get all the free games?
Why not play them as independent spins?
That is how my slots works and it works fine.

I would not call anyone a name, but just because it does not interest you does not mean it does not interest me or others. I really appreciate the industry insight DogBoy is sharing with us.

I will continue to follow this thread with great interest, although perhaps renaming Fleur's OP is in order at this point.

Heya,

Yup, I asked RTG that same thing when things got moving...
I think they altered it so that at least it didn't suck down the free game random results all at once upon trigger (overcoming the Cleo issue).

I'm not 100% sure on the rationale for requesting batches from the servers, but that's a coding item that falls beyond our area of expertise.

I thoroughly agree that this has been a most interesting thread. Did I understand all of it. Not really but I still found it very interesting.

Way to go. :thumbsup:
 
Very interesting thread and thank you DogBoy001. Please become a regular contributor to this forum. Your insight is huge (you even have VWM thanking you :)). Plus you are debunking the "slot game remembers where you left off and how much you are up or down" conspiracies with real facts. There are some who will never accept this as reality but their arguments to the contrary will be met with yawns (moreso than in the past :)) which is a GOOD THING.
Again welcome and i very much look forward to heading more of your posts.:thumbsup:
 
Welcome to the Forum DogBoy !! You definitely sound like you know what the hell you are talking about...:thumbsup:

My only hindrance to convincing me that all these online slots are totally random though is the fact that everyone on this forum has not won as well as we did before the US Market was cut off in Oct. 06....before that we won and we won often and big amounts too, and the "Winner Screenshots Thread" on here is more than ample proof of that with all the Winning Screenshots in large amounts and a hell of a lot of them from MG casinos...

But since Oct. 06 the frequency and dollar amount of Winning Screenshots in that thread has more than dramatically decreased since the US market was practically cut off...So my question is how do you explain that phenomenon ?

And I seriously doubt that I am the only one on here that has noticed this.

I also think it would be interesting to hear Eliot Jacobson's take and thoughts on all of the posts in this thread regarding randomness too...:cool:

Again, look forward to seeing more posts from you DogBoy !! :thumbsup:
