I logged into and played at Inetbet last nigt, and saw the newsscroller announceing the Clepatras Gold Random Jackpot of 8500 $ had been hit yesterday, by "heijac". Good for him/her I thought, and blew 150 dollars on that Aztec-slot. Then I read the last Inetbet newsletter, only to see this:

"Since the last edition of the Newsletter was published over 90 of our Progressive Jackpots have been hit along with some large payouts on other games. Congratulations to you all. Take a look at the table below for some of the recent big winners who have been playing our VP and Slot machines.

...
heijac Cleopatras Gold Random Jackpot $1967
heijac Cleopatras Gold Random Jackpot $6711"


This leaves me with these questions:
- Is the chance of winning the random jackpot bigger if you bet max pr spin(like rapid fire jackpots) - and is heijac doing this?
- is heijac playing cleos gold day and night 24/7?

I ve played RTG-slots at inetbet and others for a year and a half years, one dollar a spin, and NEVER won a random jackpot. Whats the odds of one person hitting it three times on the same slot in a month at the same casino?? :what:

Ummmm....

Actually it was hit Thursday afternoon around 2PM. I was playing Cleo and left for only a couple of minutes...came back...and it was gone. It seems strange the same player could hit the last three Cleo jackpots when everyone else can't even hit one. How do we know if "heijac" is really a real player or maybe someone closely related to "STONELADY" from Zany Bingo?

Makes one wonder?

This is what I think.

A high roller comes to the casino and bets 20$-100$/spin and plays slots. Because the chance for hitting the random jackpot 'increases' with bet size, this player manage to win several of the jackpots. This is probably also what the casino would claim which they also did last time. And it is probably correct.

But when you start to think about this, it only makes sense if the meaning
'chance of winning the jackpot increases with bet size'
actually means
'change of winning the jackpot increases tremendously with bet size'

So it is not a 'linear' function in bet size.

It was was a linear function it would mean that 200 players each betting 1$ would have same chance that one of the hitting the jackpot during the same time a player betting 200$/spin would have. However there are 1$ slot player
playing all the time(probably 200+ players) and several jackpost is not won every hour as some high rollers manage. QED
(Actually betting 100$ and winning a jackpot of a few k$ is not much different from hitting the bonus round)

Because it is not a linear function at RTG casino is means that payout% increase with bet-size. So low rollers are playing at a higher house edge.

This has not happened at Intercasino to my knowledge, which means the I believe the function is liniear there. And most of the marvel jackpots wins I have heard of has also been won by low rollers. (because there are so many of them compared to high rollers).

This is just yet another nail in the coffin to RTG slots. I like them but as a low roller the slots are just robbing me and the chance of winning the jackpot are way way too slim. (how many has seen post of jackpot wins with bets of 0.2$ or 0.4$ at RTG? I have seen several from Intercasino but not from RTG)

Besides the payout% for RTG is never published. But even if it were published it would be an average where low rollers should except it to be lower for them.

Not the case

All that is probably true, but Casino operators (and I think it was iNetBet) that claimed the random jackpots are set to hit on a certain amount of spins not on the size of the bet.

I have to agree with everyone else posting that the bigger the bet the more likely you are to hit the random jackpot. Other wise something fishy is going on!

If that's the case, then it's not "random".

Random = everyone has an EQUAL chance to hit it, no matter what their bet.

It's kinda similar to how the publishers clearing house drawing was back in the day - you had to actually buy something to have a better chance of winning (or win at all). The only difference in this case is you have to bet a certain amount per spin to have a better (or any) chance.

It is a completley random jack pot and have seen players hit playing .20 a spin or 100.00. Meaning it is random for the players. What is not random is the Jack pot itself, that is pre set to hit on a certain spin number. That is why you see usually the same amount in the jack pot when it hits. If every player played.20 per spin the jackpot would hit with a low balance like 1000, but if everyone was playing 100.00 per spin than the jackpot could go over 20,000 like I have seen when casinos give huge bonuses. I hope this helps in dis spelling some misbeliefs

Does that mean that the random jackpot will hit on say, the 20000th spin each time. If so, that would surely mean that after a jackpot is hit it would be meaningless to aim for that during the first couple of days after it is reset.

Don't quote me, but I never play till the jackpot has been built by someone elses hard earned money. That is if I was playing for the random Jack Pot only.

The most logical and fair solution would be that chance for hitting the jackpot is proportional to the bet size. (Ie. liniar function).

This way payout% is the same for all bet-sizes and small bets can win the big jackpot also. I like this the most.

Another solution is that you only win a part of the jackpot. (Ie a 1$ bet would win 20% of the jackpot where as a 5$ bet would win 100%). This is also a fair solution and chance for hitting the jackpot is now the same for everyone (though jackpot size differs).

Unfortunately neighter of the cases seem to apply at RTG casinos.

You could argue that due to the huge house edge at slots it would be fair that high rollers faces a smaller house egde. And this is also the case in Vegas. But this is for different slots. Ie. playing quarter slots compared to $ slots.

When it happens for the same slots I feel low rollers get cheated but only because RTG do not tell players that. (Nor publish any payout% records for that matter).

Hmmm... if it is set to hit on a certain spin # is this the same # each time a particular slot resets? Or randomly selected by the software after a jp is hit? Is it possible "heijac" may have found a pattern? Or is s/he simply setting Cleo on 20 cents a spin, infinite autoplay, stop on jackpot?

Hi everyone,
Different posters have put forward a number of points/theories/speculation in regards to RTG Random Jackpots which I feel need to be clarified.

Firstly I am unsure as to why people would think that a "Random" Jackpot would hit on a given number of spins or be determined by any other factors. As the name suggests this is not the case. These Jackpots hit at random and they are not determined by spins, bet size or any other variable.
If you take a look at the Random Jackpots listed in our previous newsletter Old / Expired Link you will see that there are no set values for when a Jackpot will hit, neither is there a given timeframe.

Take for example the Cleopatra’s Gold Jackpot. This has been hit on 14 occasions this year. The full data is as follows:

Machine * Date *Days Prior * Bet * Win

Cleopatra’s Gold * 1/1/06 0:35 * - * 100.00 * 4,718.24
Cleopatra’s Gold * 1/21/06 19:53 * 20 * 10.00 * 5,859.21
Cleopatra’s Gold * 2/18/06 20:26 * 28 * 10.00 * 7,114.38
Cleopatra’s Gold * 3/17/06 10:24 * 27 * 0.20 * 6,321.94
Cleopatra’s Gold * 3/23/06 10:57 * 6 * 5.00 * 2,279.23
Cleopatra’s Gold * 3/25/06 23:20 * 2 * 10.00 * 1,328.83
Cleopatra’s Gold * 4/5/06 7:56 * 11 * 1.00 * 3,892.64
Cleopatra’s Gold * 4/13/06 11:21 * 8 * 10.00 * 2,748.34
Cleopatra’s Gold * 4/22/06 12:02 * 9 * 10.00 * 3,586.83
Cleopatra’s Gold * 5/17/06 6:46 * 25 * 1.00 * 5,165.50
Cleopatra’s Gold * 7/6/06 12:52 * 50 * 2.00 * 13,557.33
Cleopatra’s Gold * 8/3/06 0:11 * 28 * 10.00 * 6,672.42
Cleopatra’s Gold * 8/8/06 0:41 * 5 * 10.00 * 1,958.59
Cleopatra’s Gold * 9/14/06 14:54 * 27 * 10.00 * 8,100.48

As you can see there is no set figure for when the Jackpot will hit. What would be the point in having a Random Jackpot that hit in and around a given figure? As chuchu59 says nobody would play the Jackpot until this figure was reached.
You can also see that there is no set amount of spins needed for the Jackpot to hit. I included the Days Prior information to show more clearly the timeframe in between wins. The data shows that there was a gap of as little as 2 days and a max period of 50 days in between the Jackpot hitting on this particular machine. The number of spins, in between all of the above hits, was different. The figures presented show too that the Jackpot has hit on a wide variety of bet sizes from as little as 20c to $100.

As I said previously these Jackpots are totally random and anyone at any time can hit them. This is regardless of bet size, Jackpot size, amount of spins or time prior from the last Jackpot hitting.

I hope that this clears things up for everyone.

I must thank you for providing the data, I wish more RTG data was avaliable (like payout%). And I sure your data are real and they actually prove one of the speculations raised here.

These Jackpots hit at random and they are not determined by spins, bet size or any other variable.

You say bet size as no influence on hitting the jackpot, but I am 100% convinced you are wrong. You can claim that even a small bet has a chance to hit the jackpot, but you can not claim that it has no influence on the probability for hitting it.

And even the data you provided actually proves you wrong. 9 out of 14 jackpot wins (64%) of the jackpot wins was at bet size 10$ or more. If it had no influence this would mean that 64% of the bets on slot are at a total bet of 10$ or more statistically. This is because the sample would then simple be uniformly distributed over all bets. I find it impossible to believe that 64% or more of the bets on slots are 10$ or higher.

For Intercasino the chance of hitting the jackpot is proportional to the bet size and this is good, because it means payout% is the same.
p(x)=probability for hitting jackpot
x=bet size
p(x)=k*x

You claim that for RTG casinos the formular is:
p(x)=k

For RTG jackpots I do not even believe the function is proportional.
Ie p(x) =k*exp (x) or p(x)=k*x^2
And it is extremely unfair not telling the players this because this means
payout% of the slots is not constant for different bet-sizes. This is the big issue I have been raising in this thread.

If you statement was true dont you think the jackpot could be exploited by autospinning at bet 0.01$ (1 line at minimum bet) ? And betting 0.01$ would give the best payout% in that case.

I knew that someone would jump onto my post with some form of statistical analysis.

Thanks for your feedback Zoozie however I can assure you that the Jackpot is random and not dependant on Bet size.
Please remember that you do not have all of the variables i.e you do not know how many spins were made at each individual bet size etc
If 70% of spins were at $10, 10% at $1, 10% at $2, 5% at $100 and 5% at 20c then what you are saying would not be correct.
I have only provided a small section of data from one particular machine. You cannot apply your formulae to this small sample as it is not perfect data.

I could have provided you with data from a different game which showed the majority of the jackpots being hit from 1c bets. In fact our Caesars Empire Random Jackpot has only ever hit at the $1 denomination. That is not to say that tomorrow it will not hit at 20c or $10.
However as Cleopatra’s was the game in question earlier in the thread this was the data I thought most prudent to post.

As I posted previously the Random Jackpots are just that, Random. Bet size has no influence.

Thank you for responding. I can garantie you that I am not on RTG rambling mode, but I actually believe I have a case.

Try look at the jackpot wins from other slots and if shows 50%+ of the jackpot wins was on bet 10$ or more, you know you are wrong.

But even the small sample show 60% bets of 10$ or more and I believe
only 10% (at MOST!!!! probably a lot less) of the bets on slots are 10$ or more, so even this sample would then be mathematically very very unlikely. So I actually believe your sample to be sufficient. However just giving is a few sample for other slots more would settle this argument forever.

However you should be arguing that chance of winning the jackpot is liniear (proportional) to bet-size, because that is actually the most fair method (But I still do not believe this to be true for RTG). I am surprised you defend a unsymmetric distribution that actually screw high-rollers.

You do realize that IF the probablily for winning the jackpot does not depend on bet size, then the slot would have maximum payout% at bet 0.01$?

Lets say the jackpot is 4000$. This means the jackpot could cover 400000 spins (0.4M) alone on bet 0.01$. But remember the paytable from the reels also contribute. So with a bankroll of 4000$ you will have have about 4M spins before going bust if the payout is as low as 90% without the jackpot. So if the 'constant' probablity for winning the jackpot is higher than 1 to 4M then the slot would have 100+% payout (if base paytable from reels gives 90% payout which is a low estimate).

I really hope the chance for hitting the jackpot is higher than 1 to 4M....

Anyone not conviced yet?

My mom hit 2 rapid fire jackpots in 2 weeks time at Intercasino. She was only spinning 45 cents a spin. I've been playing there for 2 years and haven't hit one yet!! LOL

As I posted previously the Random Jackpots are just that, Random. Bet size has no influence.
I have also been playing the RTG random jackpots for YEARS on different denominations from $.20-$5.00 but could never bring myself to play $10 EVER. So as Zoozie says
Anyone not conviced yet?
I have believed it for a long time that the higher the denomination played the more apt it is to pay off so , I don't think it's that random.

The other reason for this belief is, I also play at Intercasino, Sands of the Caribbean, and have hit MANY rapid fire jackpots ranging from $500-$1400 with wagering spins ranging from $.90-2.25, and NEVER had to bet any higher. Now this is called RANDOM, not as your stats show, just 1 winner out of many that bet under $10 ...that is called appeasing the masses with a token in my opinion.

In fact our Caesars Empire Random Jackpot has only ever hit at the $1
This is intersting to know, for my husband has played this NON stop for as long as it has been offered and he has NEVER hit this (almost like 24/7 player on this) for thats how much he liked it and he never could bring himself to go over the $5.00 mark either....random? I think not, for how does one hit this random jackpot 2-3 times in a month (with higher denominations?) if others that are playing for a longer period ( with lower bets?) can not?

The odds just aren't lining up or something here...and that is as good a reason to stop playing heavily at any RTG in my opinion as I need.

I have to agree

....random? I think not, for how does one hit this random jackpot 2-3 times in a month (with higher denominations?) if others that are playing for a longer period ( with lower bets?) can not?

My thoughts exactly!

Now if this person had hit 3 jackpots on the same day playing then I could possible understand that maybe they were playing at a time when the slots were all hitting. BUT for the same person to hit 3 jackpots days aparts (and no one else hit the random jackpot between their 3 hits) is just plain fishy to me and all three hits won on $10 bets.

To quell their doubts, can you show us the stats for other random JP slots like Fruit Frenzy, Goldbeard and Ronin. Statiscally, the more info the better.

Just wanted to try out something tonight to see how "random" really works.

I haven't played at VIP Casinos in about 2 months, decided to give the "Rapid Fire" random jackpot a go at it and played for a solid 5 hours and would you believe it!??? Yes, I hit the "random" jackpot of "Rapid Fire" .THAT is what I call RANDOM.

Screen shot will be posted.

Now, I have played at the RTG casinos for many hours, months, years and NEVER had the pleasure of hitting one of those. Odd, maybe, random, I don't think so at all, after tonights play proved to me that it isn't so. I didn't even have to go OVERBOARD and play $9.00 a spin...just the normal $.90-2.25 as usual...go figure!

You cannot apply your formulae to this small sample as it is not perfect data.

I ran a statistic analysis based on different values on the percentage of bets that is 10$ or more.
Out of 14 random picked spins made on the slot , what is the probablity that 9 of these (or more) was with total bet 10$ or higher?.
(In the sample 9 of the 14 jackpot wins was with bet 10$ or higher. If the jackpot does not depend on bet size, then this would be a uniform random sample on bet-size on that slot)

p= probablity of 9 or more (out of 14) of the spins was bet 10$ or higher
b=percentage of bets that is 10$ higher

For b=0.4 (40%) gives p ~ 1 to 16
For b=0.3 (30%) gives p ~ 1 to 120
For b=0.2 (20%) gives p ~ 1 to 2500
For b=0.1 (10%) gives p ~ 1 to 750000
For b=0.05(5%) gives p < 1 to 1000000000

So if the casino has a massive ammount of high rollers so 30% of all spins on the slot is 10$ or higher, then the data you provided seems reasonable.

However I do not believe that even 10% of the spins are with bet 10$ or higher, which means the data you provided are next to impossible if
jackpot does not depend on bet size.

Earlier in this thread I showed that the probabilty for hitting the jackpot each spin had to be less than 1 to 4M if the statement was correct(this did not use the data provided). So if we assume 30% or more spins on the RTG slots are with bet 10$ or higher then slot would have been feed more than 0.3*4M*10$=12M$. So 0.033% of the coinage is used to build the jackpot, which is just too low and so far from the standard. (and the estimate is a lower bound ignoring all the small bets!)

I can not do more mathematically sorry, but something is fishy here.

Jackpot wins DO depend on bet size, but the big issue I have been raising is that it is not liniear which would have been fair.

I hope INetBet will investigate this matter as I find it unetical that the casino give false information to the players (that jackpot win do not depend on bet size).

And if jackpot win do not depend on bet size, you realize that high rollers will face a lower payout% than lowrollers? I thought casinos would treat high rollers better than that.

By the way, I've been provided a spreadsheet from iNetBet that covers the random jackpots they've incurred since January (56), and they do seem to be quite random.

The largest wins are from .20 cent bets ($13K to 25k). The larger bets don't seem to generate large wins, probably because most players are betting smaller (my guess). Kasino King - there is opportunity here :D.

If more information is needed, I can contact RTG if you'd like.

I would not mind having a look at the bet-sizes that won the jackpot.

The size of the jackpot is not important and I am sure that at least is uncorrelated to bet size.

Just a few more samples would help me.

However I still find it hard to believe RTG implemented it so jackpot win does not depend on bet-size, because that is screwing the high rollers.

Example to demonstrate:
Roll a dice. If you hit a 6 you win you money 1-5.
However lets say each roll has a 1 to 100 (does not depend on bet size) chance to win the jackpot that is 100$

If you bet 2$ and roll the dice, then you AVG win will be 2$ (from the dice game) + 1$ (from jackpot) =3 $.

So EV from this game is 1$.

However if you instead roll the dice but only bet 1$ each time. Then the your average win each game will be 1$ (from dice game)+1$ (from jackpot) = 2$ So playing this game twice each with bet 1$ instead will give you average win = 4$. (which is higher than 3$ when you only rolled the dice only once but with bet 2$.)

The same mathematics applies to the RTG slots if jackpot does not depend on bet size. But if it was true then you could just bet 0.01$ to have same chance to hit it.. And I showed earlier than chance of hitting the jackpot then has to be less than 1 to 4M or the payout of the slot would be higher than 100%.

I would find it very strange if these slots had a higher expected payout, possible over 100%, for low rollers.

There are two obvious way to make the slot "fair": the probability of hitting the random jackpot could be proportional to the player's stake, or the player could win an amount proportional to his stake, so that, for example, a $1 player could win the whole jackpot, and a 1c player could win 1% of the jackpot.
