In Cell stage you move around and try to eat the smaller organisms than you. You can choose if you want to be a herbivore, carnivore or omnivore. 



In Creature Stage you gain legs and arms now you can walk around and gather parts attack and socialise. Here you can evolve by giving birth. And I’ll let you explore the rest. In Creature Stage you can also fly if you give your creature wings.

 In Tribe Stage you aren’t just controlling one spore any more, your controlling an entire tribe hence the name. Your objective is more or less the same as Creature stage. But in a pack mode. Instead of socializing with one Spore you socialize with a tribe and your own tribe comes with you. Your chieftain or chief conducts your band and the other members of your tribe play instruments. You can also get weapons, instruments, huts and you can domesticate animals.

In civilisation stage you are controlling a whole city you can control vehicles, planes and ships. Your aim is to seize control over the other civilisations by religious means, war or diplomacy. You can now build houses, work houses and entertainment buildings.
