Mah jong online play not the solitare one?

Hi, I want to play the real mah jong where there are 4 players (probably human players online) the you take turn on getting a tile on the pool of ties. where the objective of the game is to form trios and a pair... trios can be three sonsecutove number. (ie. 1 2 3 babmboo or 789balls etc.) and a pair. SO, is there any game here online which lets you play with three other poeple in the world??? thanks in advance!!!|||Don't know if any games match that exactly, but as well as Yahoo games there is Mah Jong Towers Eternity at Atlantis that's popular.
