Pocket Ants: Colony Simulator for Android
The player's task is to develop an anthill made in the form of a system of labyrinths. There are different types of ants, collecting resources, building facilities and even wars. There are no buildings for the production of units - they are produced by the Queen quite realistically.
You need to feed the queen with the resources she requires, as well as to expand the anthill to accommodate incoming ants and to order individuals the Queen must produce. By creating an army, you can start war with other ants, or protect your settlement from hostile creatures such as spiders.
