Tony, I just typed a REALLY long response to your post and lost the whole thing. I will try to reconstruct it later, because I think you'd be interested.

The short answer is the Bible does not cover gambling; Christians who are opposed to it do so based on principals such as not taking something without giving value in return and the protection of "family values". I researched all of this before really playing with any seriousness and found all of thse arguments to be lacking.
