Not necessarily. Despite having pretty bad odds (in favor of the house) compared to other casino games, many people find roulette to be fun and addictive. The same goes for craps, and really applies to the slot machines.

[Thinking about slots, reminded me that in my previous comment I was talking about table games when I was talking about roulette being the worst odds. I don't know if that's true. I haven't crunched the numbers, but that's what I remember being told as an employee.]
