Keno
Keno is the worst game in the casinos, judging by
casino advantage. Depending on where you play and
how many numbers you choose the house advantage will
be 20% to 30%. However for those on a tight
budget your money can last a while in the keno
lounge since it is such a slow paced game.
Be especially wary of keno outside of Nevada. Maryland
has state run keno in a lot of the bars. It has a
house advantage of about 50%. I believe other states
that have keno to be just as bad.
