That's how they took away our RTP and pay those all streamers. I mean, they are far different like before. Small multipliers are more scam than hunting high multi. I like Stake before. Now, they are making it hard for us to cope up with their new as they said, "improved" system which is opposite.
As far as I know, RTPs are guaranteed by slot providers and Stake can't change that. I mean, the casino has the ability to set one from these three levels of RTP on their website - low, medium and high. I don't know which one has stake set but they can't make custom modifications to RTP as far as I know and they also can't manipulate with it, it's managed by slots providers and those slots providers are audited by the government. EGT slots have offices in my country and I know that they get regular audits.
Btw if you don't like Stake, then change them to another casino. There are many trustworthy casinos on this forum that don't get complaints that Stake gets. If your favourite games are slots, then Metawin will be a good choice for you because Metawin guarantees the highest RTP on all of their slots. It also let's you connect with Web3 wallet and deposit/withdraw without a pesky human interaction.
