We live in times where almost everything is possible with software these days, but I have not seen any Casino having code that shows in
real-time what the actual RTP is for ALL their games.
You will go to a site and you will click through several steps to find the RTP, but the RTP is simply the advertised RTP for that game. The latest Slots have multiple RTP settings for the same Slots (eg Hacksaw Games) and you never know on which RTP that Slot is running.
Can Software developers not write "Provably fair" code.. to enable people to click on a option in the game to "test" the actual RTP of the Slot at that given moment?
There are a lot of discussions in casino chats and forums on casinos hiding the actual RTP for their games and the RTP and Variance being adjusted in real-time to "feed" during certain periods. A provably fair system to check this will build more trust and it will also reduce frustration and negativity from gamblers on these platforms.
You have provably fair systems to check the bets, but we do not have provably fair systems to check the real-time RTP being used by the casinos.
It seems, that you and some people here don't really know how the things work in case of both, online and real life casinos. Online casino is not a business where you buy the script from a shady guy and run installed script on cheap Hetzner servers.
Licensed online casinos are constantly and strictly audited to ensure that the whole gambling process is fair and safe for gamblers. I don't know if it's general or not but I can certainly say that in some countries there are laws where casinos can't lower the RPT under a certain limit, in Europe casinos are very well regulated. Every single process is tested and the results are submitted to the gaming commission, they can retest anything anytime and it should prove the previous fairness.
