So what exactly are seeded runs and how to they work?

[GoldBoyLake]

I've had my fair share of the original game (75 hrs) but i do not know what 'seeds' are, is it like minecraft (Sorry for the corny example). Please enlighten me.

[Curious Duck]

Yes it's like in minecraft.

A seed is a piece of data used to determine what items/enemies etc are within the rooms.

Basically yeah. Same floor layouts, same room/enemy/boss/item layouts, same pretty much everything. A good way for people to directly challenge each other on singular runs

Do achievements still count on them? I mean if the layout is the same it's easier.

No, you can't unlock anything on a seeded run.

Does anyone know how seeded runs work with the D6 (assuming it still exists)?

As long as you have the items unlocked it will be the same. Edmund said that everything will be the same until something you don't have unlocked is encountered and changes from there will happen (item wise). The floors would still be the same though.

Every run of isaac is seeded, it's just that the regular runs are randomly seeded. In reborth you'll be able to give the seed of a run you've done to a friend (or even yourself) to see how they fare comparatively to you. Of course, in those you won't unlock anything.

What if you thought a really OP one and just did it again and again and again to easily unlock everything?

Not funny! :D
