Beware of any class II slots....
May I add that all should beware of any "Class II" machines of any type in Indian casinos, such as those in Florida in Seminole and Miccosukee casinos. I have yet to find the true hold on these machines, but I am pretty sure it is extremely high. If anyone knows, please let me know.
When in a regulated casino, where they have Pai Gow Poker, give it a try at a $5 dollar table for cover use. The game is extremely slow (over 40% of the hands result in pushes), thus it is extremely non-volatile in spite of a PC of about 2.8%. There is even a strategy for playing the game. Your play gets recorded if you hand over a player's card. If it doesn't put you to sleep, two twenty dollar bills can last literally for hours. If you're lucky, you may even win a buck or two.
It has become my favorite non AP game in the casino.
