Hello. As for now game does not have this feature yet i made small program for handling randomness. In my program randomness is based on how many times did empire appeared before. For example if we have empires A and B which appeared 3 and 5 times then probability for A will be 5/8 and for B it will be 3/8 so A has more chances to be chosen as next empire. If someone interested then here it is: Doodle Randomizer for Doodle Empires on github!
