My 11-year-old is a SET shark. She takes it with her to summer camps and challenges the counselors. She doesn't play for money (as far as I know), but she is pretty merciless. I don't think a camp counselor (usually 5-15 years older than her) has beaten her at it yet, and she's been doing this for a couple of years.
