How many Factories ?

I think it is just coincidence or they have a cap. I am on level 27 and I have 8 factories. Next level 28 does not unlocks new factory limit.

It's not every 3. I got my 9th factory between lvl 29 and 31. I'm lvl 32 and I still have 9 factories.

Honestly, I'm curious too.

Some guys here https://www.reddit.com/r/SCBuildIt/comments/382o25/at_which_levels_are_new_factories_unlocked/ said that after level 6 you may unlock additional factory slot at every 6th level. 

Right now, I'm @ level 18 and unlocked the 7th factory. so it might a viable info, but I cannot guarantee. 

I keep searching. cuz it might be related to the number of population at a specific level, I don't know.Just guessing.

If someone knows more about the number of factories that a player can have at a specific level or requirement, or what we should achieve in order to get more factory slots, let us know.

Thank you.

Hi, after searching further I found this.http://simcity.wikia.com/wiki/List_of_industrial_buildings_in_SimCity_BuildIt

It may clarify how and what are the conditions of building factories.

In my opinion is a bit limitation, but at least, we can know what we can do, how many we can build and when.
