The Griffin Book is a listing of known or suspected
gambling
cheaters and
advantage players published by
Griffin Investigations, a firm that monitors
casinos. Those listed may be anyone perceived as a
threat to the casino's profits, including
card counters, people who mark cards and those who try
to cheat
slot machines. The book keeps pictures either obtained
from a photo of the individual when caught or from
surveillance photos.
