I used to play this a ton (often as a drinking game). The wiki does a good job of explaining the basics and I'd always do the no talking + point of order variants (+ a few others). My favorite type are:

1) rules requiring awareness of card order. "Have a nice day" is standard on 7, double 7's is "very nice" etc. Stack rules like that when combinations and/or cards of a suit are played and people have to remember 5 things they have to say or do after a card. Get's difficult over many rounds.

2) ice-breaking rules (if you're playing with new people). Friendly ones like "you must compliment _ when a _ is played." Great way to build/open someone up

3) rules changing play order. Aces reverse, add rules that e.g. skip a player and you'll have everyone waiting in suspense to see if the person who's turn it is actually knows its their turn. If not, "delay of game".

Play it with friends you'll be surprised with what people come up with!
