Landbased casinos has a really poor rtp on slots. I guess you are there for the experience. Unfortunately certain providers offers different rtp versions online and some casinos choose the lower settings. Recently we heard Videoslots lowering rtp on PlaynGo,Red Tiger,IGT etc. Very unfortunate!
I guess the casinos think they can get away with it, because not many knows or cares about rtp, as we slot neards do. Fact is that lowering rtp from 96-94% will give the player 34% less playtime, which is ridiculous.
