Each casino has its own set of Terms & Conditions. In fact, they often have several sets -- one general one and one for each bonus. They tend to be long, complicated, and often difficult to follow. Still, a smart player will read them carefully before placing his first bet. One small mistake will be enough for the casino to invalidate your winnings.
Still, how many of us bother going back and re-reading those T&Cs each time we play? I certainly don't and I doubt that many others do either.
We are playing to have some fun, not to get a doctorate in the casino's rules and regulations.
The problem is that casinos often change the T&Cs without notifying players -- and then tell you that it is your responsibility to keep up with the changes.
Why should it be our responsibility? My bank changes its rules from time to time, and when it does it sends me a notification in advance. The same is true with my credit cards. If they are going to change their interest rates, their fees, payment dates, or anything else, they not only send me an e-mail but they also send me snail mail as well. Again, this is done in advance of the effective date.
Is it really too much to ask of a casino to do the same? Every casino I am registered at sends me loads of e-mails. Generally they are offering some bonus to come and play in the next few days. If they can do this with every player registered at the casino, they can also send them e-mails when they change the T&Cs.
The e-mail should not include the entire T&Cs -- nobody wants to read them the whole thing again. It should only tell what has been changed and it should do so clearly. (In fact, it would be nice if casinos were to reword all their T&Cs one time to make them easy enough to understand without a law degree.)
