Board Game Arena

I think its a good idea to put scoring options for Stir Fry 18. Its too easy to reach 50 points making it really short, and not to mention unfair if you dont play first. Possibly, there can be an option like if you want short game 50, medium game is 100, longer game 150.

P.S. im not sure how feasible those numbers are. Just throwing them out there but you get the point

If it's not in the official game rules then it's very unlikely they will be implemented.

The main difference between board games online and board games at home:

You can't make up house rules.
You don't get do-overs (at-least not on some games).
You can't look deep into the evil eyes of your opponent to see if they are bluffing

There is an official rule variant "Master chef" (play to 300 points), which is the only variant available on BGA at the moment. Almost no one plays this variant, because it is too long.
The best would be to play a couple of short games than one longer game.
