Rook was also called "Christian Poker" my dad played it a lot at Wheaton College, back in his fundamentalist youth (he's since reformed). The students had to sign a pledge not to smoke, drink, go to the theater and play cards. Rook, it seemed, didn't count. I haven't played it in years, but it was a fun card game.

We also had a flinch deck when I was growing up, but I can't remember the rules anymore.
