They do not have a legally mandated rate, they have a legally mandated expected value and there are strong statistical tests done of the RNGs. Source: have worked with a situation which required me analyzing the process of getting betting software through regulatory approval. Edit to add: Here's the relevant regulations in Nevada. https://gaming.nv.gov/modules/showdocument.aspx?documentid=4548 https://gaming.nv.gov/modules/showdocument.aspx?documentid=4... The thing to search for in the regulations is the "Theoretical hold percentage", which is the expectation for the house expressed as a percent. The fact that they call it "theoretical" is probably enough to demonstrate that it isn't a mandated rate, but the theoretical average rate.
