how to use the scoring page

Everytime someone wins a game, simply fill in what everyone has and hit "process hands". You fill out hands by typing the numbers of letters of their set into the boxes, so if someone has a pung white dragons, you fill in "ppp", or if someone has a chow 123 of characters, you fill in 123 and click 萬 next to it to indicate that it's from the characters suit. Alternatively, you can type 'B', 'C' or 'D' to have the script auto-set the suit to 'bamboo', 'characters' or 'dots' respectively

You don't need to indicate whether something is a pung/kong of terminals, because obviously filling in "1111" or "999" should already be enough information for the system, but you do need to click the concealed checkbox if you had any set in your hand rather than on the table. However, if someone won by a limithand, instead of filling out their hand simply select the limithand that they won on first, then click the "limithand" option for that player. Fill in other players as usual.

While for the winner you need to fill in everything they had (so that the system knows who won, because only the winner has a mahjong forming collection of tiles), you can ignore chows and pairs that generate no points when filling out the other players, since they won't matter to the score calculation anyway.
