Goblin supports German and English language. I will add more information later.top
I think I do no need to comment MacMahon and Swith system.
Goblin behaves like MacMahon except for a different scoring strategy. I you win a game and won the previous game also, you will earn as many points as for the previous game plus a little bonus (default is 0.1 points). If you did not win the previous game you will get 1 point. Lost games are scored similar: first defeat scores 0 points, immediatly following defeats score -0.1, -0.2, etc. Jigo counts 0.5 points allways.
In Hahn system scoring depends on exact game result:
|Winning my 40.5 points or more||1.0|
|Winning by 30.5 to 40 points||0.9|
|Winning by 20.5 to 30 points||0.8|
|Winning by 10.5 to 20 points||0.7|
|Winning by 0.5 to 10 points||0.6|
|Loosing by 0.5 to 10 points||0.4|
|Loosing by 10.5 to 20 points||0.3|
|Loosing by 20.5 to 30 points||0.2|
|Loosing by 30.5 to 40 points||0.1|
|Loosing by 40.5 or more||0.0|
In one of the next version you will find an option for counting by single points, so scoring step is 0.001.
