Don't know much of anything about online software these casinos use. Can I assume proprietary means they developed the software themselves and own all rights? Can casinos control their programs on any given day to pay or not pay? For instance, in Vegas, certain machines are "set" to pay. Can online casinos do the same? Also, is there really something called a Random Number Generator? I saw a program on TV a few months back that basically was saying "no". The program was about a person who was arrested because he worked in Vegas on programming and was cheating to win. Thanks.
