Thankyou Nicolas for answering the question without answering the question
Q: Can individual Rival operators alter their slot RTP at will?
A: I'm going to be blunt; I can't answer the question that is on everyone's mind. It would be in breach of my contract.
There is not a shadow of a doubt that every Rival casinos can change the RTP for individual slots. It can still be seen very easy. Log in some different Rival casino and load some different slots. Then click the "HELP" option on the slot. In the end of the help file you will see the RTP. It is now listed at 94, 95 or 96.
Since the same slot had different payout at different casino this can only happen if:
1) The casino can configure RTP for each slot. (regulary change)
2) The casino pick a RTP configuration for each slot when they setup their casino operation (one time change).
However this was the situation 1 year ago, it might have changed since!
Rival used to show this RTP on the help page with % ie. as "95.23%", also it was once listed with 1 or 2 digits also. At that time I saw that the same slot etc. was configured between 93% and 96% and the steps was in increments of approx. 1%. This is quite normal, it is actually totally identical to IGT/WagerWork slots.
Ie. for a specific slot like "Scary Rich" you could would see one of the following RTP. (I am just making up the decimals now, can not remember them)
93.5%
94.6%
95.3%
96.2%
The rival casino operators simply picked some pre-defined RTP configurations for each slot. The software would then automatic present the RTP% for that slot in the HELP page. Very fair and honest and I truely believe it indeed was the truth.
Shortly after "Scary Rich" was released something very interesting happened, and I guess it is due to Rival Casinos was not aware players could see
the RTP configuration. Of course they do not want that since players will then notice another casino has a higher RTP setting.
Suddenly the RTP in each help file was changed from the format:
"94.6%" into "about 94".
Notice there is no % after the 94 and this is still the case. Also while there before were 93.x% (and even 92.x%) slots, they were now ALL listed
as one of the three:
"around 94"
"around 95"
"around 96"
Did this simple RTP presentation change in the help file magically happen with
all rival operators setting their former 92% and 93% slots - to now 94%? Coincidence...
Lets say the RTP presentation is bogus and now some casino are setting some of their slots to the lowest
RTP configuration... The RTP will now be shown as "around 94" as players will think they are getting a fair game.
All Rival slot games except two was now showing "around 94" or "around 95" however there was two particular slots that stood out. "5 reel circus" and "scary rich". They were showing "around 80" etc. Ie. some much lower numbers. This was only visible for a very short time and then fixed for these few slots.
I believe the RTP display "fix" was somehow forgotten/not working for these slots. Instead they were indeed showing a very revealing RTP. It happens same time with forum getting flooded with posts about Rival slots had become tight etc. These posts happen all the time and rarely true, but the timing this was perfect.
Shortly after a new slot is introduced, this is "ISlot Psychedeilic Sixties" and the RTP display bug(or indeed the truth?) is back. Here is a link to a post
also showing a screenshot of "around 65".

It was if course just explained as a "display bug". However this greatly reduce my confidentiality of the RTP stated on the help page. It should
reflect the current setting of the game. For video slots there are only a limited number of configurations to choose from(pr. design of video-slots). My faith in the "RTP" publiced on Rival games are now non-exsisting. Too much wierdness going on and why change the perfect implementation rival slots had at the start. Showing "95.23%" etc.
What does "around 95" mean? Is 65% RTP close enough to be "around 95"???
The casino has two fair options for posting RTP for individual games:
1) Not showing them at all
2) Showing them with
correct value
I believe Rival is doing a:
3) Show RTP with fake values.
Sorry for the long post, but the story was tricky I could not tell it shorter.
