LOOK, THIS IS ALL YOU NEED TO KNOW.
DICE IS JUST AT THE BEGINNING, NOT IMPORTANT AT ALL.
STICKS ARE JUST POINTS.
TILES ARE LIKE CARDS. YOU WIN BY HANDS. LIKE POKER ONLY NOT.
KAN, PON, AND CHI ARE FOR TAKING OTHER PEOPLE'S TILES AS THEY PUT IT DOWN AND FORMING A SORT OF HAND.
RIICHI IS LIKE, HO SHIT, BETTING TIME, I RAISE YOU AND YOU'LL BE FUCKED.
TSUMO IS WINNING BY THE LAST TILE OR SOMETHING LIKE THAT.
DORA IS A SORT OF MULTIPLIER, A TILE IS PICKED AFTER SOMEONE GETS A KAN PON OR CHI AND THE TILE THAT'S PICKED IS A MULTIPLIER, POINTS ARE MULTIPLIED IF YOUR WINNING HAND HAS THAT TILE.
RON IS RON
RON RON RON RON RON RON RON RON ROOOOOOOOOOOOOOOOOOOOOOOOON
(Basically RON is when you get a winning hand by stealing the last tile you need from someone. Like, he puts down a Man 3, and you NEEDED a Man 3 to win, so you go RON and you win. Consequently, the person who put down that tile has to do the paying, so it's good for the one who announces RON, but not for the target).
