During 2014, 40,000,000 (40 million) people visited Las Vegas, United States of America and lost a combined total of $10,000,000,000 ($10 billion). The average odds of winning when using a slot machine are approximately 6.6% meaning that for every $100.00 put in, the casino takes $6.60, baiting players with a win but bleeding them dry in the long term, banking nearly $0.07 (7 cents) for every $1.00 dropped into them. Casinos with the worst odds are clustered within the Las Vegas Strip, and casino games with the worst odds are clustered within the middle of each casino itself.
