Any casino-offered card games similar to Rummy/Gin Rummy?

Does anyone know of any casino-offered card games which are similar to either Rummy or Gin Rummy, in that a player is allowed to pick up and use any discarded cards from an opposing player's hand? Thank you.

I have seen competitions of "International Gin Rummy" and "Kalooki", where you pay to play and can re-buy at various occasions. Also games of "Kalooki" are frequently played between friends in casinos (say £5/hand for all out, £2/hand out, £10 last to 150 points).

Hey, charlie, thank you! Actually, I shouldn't have limited my question to just card games. I now know the tiles/dominoes game, Mahjong, is similar to Gin Rummy (as far as being able to use an opposing player's discarded tiles as part of your own hand), although Mahjong isn't a popular casino game in the West (only in places like Macau and certain parts of Asia). I've heard, however, that Mahjong Pai Gow is currently offered at Harrah's Casino in Reno, Nevada, but no one there could help explain to me if that game was similar to Rummy/Gin Rummy (as far as the drawing of another player's discard goes). I'm also having some difficulty finding a thorough set of rules about that game on the internet (even at Wizard of Odds). Would you happen to know anything about Mahjong Paigow? Thanks again.

Just like rummy games, Kalooki is also meant to be played between 2 to 4 players. This game mainly depends on luck, in order to win you should get the best card. The main objective of this game is to get rid of all their cards by making melds. Pay close attention to the cards being thrown by the opponents.

MAH JONG PAI GOW is not really similar to the games you describe.
