How to balance multiball games?

[DragonEater70]

I would like to run a multiball game at some point in the future, ane I'm wondering how it should be balanced numerically.
Like I know for singleball 10:3, 12:4 are considered more or less balanced. But would it be balanced to just add another scumteam without changing the town numbers? Like 10:3:3? I mean this will definitely lower town winrate but I think each individual scumteam will also have lower winrate so it's theoretically balanced?
Is there some established norm on this?

[*]are you balancing for a 50% town / 50% anti-town winrate (i.e. 50/25/25, etc.) or are you balancing for an equal winrate (i.e. 33/33/33, etc.)?


[*]mith has done some ev calculations on vanilla multiball here, which may help a little with numbers.

1. That is a good question that I've been asking myself, and I think the answer sould be based on what will the players find most fun (which I have no idea). That's kind of why I asked in the first place, because I want to know if players are fine with a lowered town winrate if every faction has equal winrate or what.


2. Thanks I will check this out.

So let me rephrase it as an open question for everyone:

Would you enjoy more a multiball where every faction has equal chance, or one where factions have proportional chance to their size?

Thanks, I think this makes a lot of sense!

The thing I don't really like about the idea of 10:3:3 is that the town could theoretically lose even with perfect play. I don't really like to say a setup is balanced if something like that is possible no matter how improbable it seems in theory.

That is a good point, I feel players should have agency and I guess 2-3 town deaths every night might lose town the game even with perfect play.

So do you think for a 3:3 ratio of scum it would need to be something like 12:3:3? Or even 14:3:3? I mean mathematically 14:3:3 should definitely be fine but might be a bit townsided even (with PRs).
