Mahjong League Scoring

When you Mahjong, you receive the point value of your line.

Exceptions:

1. If you draw your own tile for Mahjong (including Joker swap for Mahjong), + 10 points.
2. If you Mahjong without using a Joker (excluding singles and pairs lines), double your score.
3. If you discard a tile for someone else's Mahjong, - 10 points per exposure of Mahjong winner. Example: If the player is playing the line FFFF DDD NEWS DDD and the player has FFFF DDD and DDD exposed and you discard a south wind, then you would receive -30 points.
4. If you have a wall game (where no one wins), each player receives 10 points.
