What other games to people play for real money apart from Texas Holdem?

What other real money games do people enjoy playing online?

I also like playing Rummy - www.rummyonline.com due to the fact that it's another skill game in which you have to use various strategies to win often.

I've also tried casino games, bingo, pool and skill games like trivia. Apart from casino games, I just can't really get into the rest and end up back playing Texas Holdem, another poker game like Seven card stud or rummy.

I can't get to grips with the bingo and pool games and I'm not knowledgeable enough on the Trivia. Google is no use for these games either, unfortunately!
