League Format
League Games are 60 minutes long. All players will be assigned to tables. Late players, or those waiting for a game, will be rotated in.

Online Scoring
All scores will be recorded online at the end of every game and players will be able to see their updated ranking immediately. As part of the scoring, every hand played will be logged into the system.

This event is for experienced players. If you don't know how to play please attend one of our learn to play meetups.

League Rules

25,000 points starting
Uma 25-10-(-10)-(-25)
60 minutes

Atamehane-nashi Multiple players can win off the same discard. Only the player nearest to the discarder wins bonus points and riichi bets, if any. Double or triple ron okay.
Kuikae-nashi The penalty for discarding an illegal tile is a dead hand.
Renhou-ari Mangan points are awarded for renhou.
Chonbo 10,000 point penalty off your total score after the game has ended (after uma).

Bad ron without revealing hand: Dead hand
Bad ron with revealing hand: Chonbo
Bad pon/chi: no penalty. Revealed tiles count towards 5 total revealed for chonbo penalty.

Incomplete Games
Games are to be finished within 60 minutes. In the event a game is not already finished, the 'last hand' of the game will be the one that is played while there are fewer than 5 minutes remaining. All bets or penalty points on the table will be removed from the game. The final score will be taken.

No elbows on the table. All calls must be audible to be legitimate. So as not to disturb the focus of other players, loud voices and unnecessary chatting should be kept to a minimum. Turns should be 10 seconds long at most, while the average turn should be 5 seconds long or less.

Winning: The player should clearly announce the win, reveal their hand, and declare the total points owed. Players will be expected to know point totals for their hands. In lieu of this, players will be expected to learn point tables and scoring during their off time during league play.

No food in the mahjong room. Drinks must be on the side tables. Unless specifically required or allowed, players should wait for their turn outside of the mahjong room.

Getting to PML via public transit:
Take BART to Downtown Berkeley Bart Station. Then take the AC Transit 6 to Telegraph Ave x Parker St.
