Self-DrawnGoing out (making the mahjong) with a tile drawn from the Wall.
Bonus Tiles

Each Season tile or Flower tile will award you 1 point when going out (making the mahjong). However, Bonus tiles do not count toward the 8-point minimum score required to go out – the hand must be worth at least 8 points on it own merits, before any points for Bonus tiles are added.

If you draw a replacement for a Bonus tile, and can go out with this replacement tile, it counts as Self-Drawn for 1 extra point.

 

Scoring
A winning hand is always worth at least 8 points. To this number, an additional 8 points are always added.

On a win by self-draw, all non-winning players pay points to the winner. On a win by discard, the discarder pays in full, while the two other players only pay the winner 8 points each.
