There is very good blog about these here
https://bitcointalk.org/index.php?topic=5386501.msg59833321#msg59833321I think that if they change they should do it in all available slots so that they can be equivalent for all
It is very depending on what is available from the games providers, and not all providers are doing the same way.. some providers allow to just not display the RTP on the games informations. For some game there is three different RTP levels, For some it almost self-evident that there is only one rtp version existing.
For some, casinos can just choose to not provide them..
And it is also question of payment structure.. for exemple for a game that can pay decent profits quite frequently casinos could not adopt it or not adopt a (relatively) hi rtp version of it!

Hi
Si it is true that RTP of slot games can be adapted to the casinos preferences ??
do all providers do this ?
And what about when slots are accessed directly on the casino website, here anything can happen, things like avoiding use of RNG too.
Thanks to everybody
I think in theory it is impossible, moreover, the games are certified. All slots that you access on casinos websites are provided via API. This means that the casino is a kind of an intermediary between you and software producers.
Hi BrutalFive,
The question was if RTP of slot games can be adapted to casino preferences. Well, let's say not adapted but the FACT is that casinos CAN
choose RTP settings if they are
available on software provider's side.
Look for example, the latest release from the Nolimit City game provider:

There are two RTP settings options: 96.09% & 94.13%
Some providers have more RTP settings options, like Pragmatic Play (3 RTP settings). And some, don't have options of lower RTP settings, just default/top one.
Hope this helps.
