1 - The subject casino is a California tribal one.

2 - The word "THE" does NOT appear in the Cryptoquote (nayhh haahh hahhh) so all words of three letters would be something else.

3 - I used a few words spelled in slang (like "whazzup, boss" which is what the table dealer asked me, but those exact ones aren't in there) just to make the new year a big pain. (Which it is turning into).

4 - The word "casino" also does not appear in the Cryptoquote.

5 - The subject casino is actually only a part of a larger casino property!

6 - One of the scrambled words is the name of a popular card game.

7 - Numerical denominations are spelled out (as one might expect).

8 - The last words of the Cryptoquote are the casino slogan, repeated oh, at least, five dozen times a day in its barrage of radio ads.

There, that's a "lucky seven plus one" bunch of clues to help you along.
