i don't know the right rules and i want to learn them
I know the rules... kinda...
Think of Mah Joong as a chinese card game, with three kinds of suits (bamboo, circles, billions), dragons, seasons, winds and flowers.
Flowers sort of a joker, where you get to pick a card from the bottom of the pile (and get extra points in the end). So if you get a flower, you just put it in front of you and take another tile.
To win the game, you have to get either three (or four) of a kind or straights and a pair.
The get the most possible points in the game you shouldn't mix the three suits and avoid getting straights (since they don't give you any points). So it's wise to try to collect one of the suits, get a pair of dragons and your own wind.
When I play, I usually don't care about the wind, since I find it quite confusing.
If another player puts a tile on the table that you want, you either say "pong" (three of a kind) or "kong" (four of a kind).
To make a straight, you have to get the tile from the person just before you.
Also, if you make another player win, by "giving" him/her a tile you lose bigtime (depending on how big the winner scores).
Hope this is some sort of help to you
