SimAnt is a simulation game where you control an ant colony, building it up to conquer other colonies in the yard. Your goal is to make the lives of spiders and humans miserable by invading their homes. The game features a Quick Game mode for battles with other groups of ants and a Tutorial mode to help you learn the ropes. In the full game, you start as the black queen ant and must create an ant hill and produce offspring to begin your colony. You control the output of different types of ants, including soldiers, workers, and breeders. Soldiers fight enemy red ants, while workers maintain the food supply and build out the ant hill.
The game allows you to switch between controlling different ants as needed to complete tasks. You can explore the surface, collect food dots, call in troops to battle spiders and caterpillars, or invade other ants' hills to eliminate them.
As you navigate the yard, be mindful of hazards like rain and lawn mowers. When breeders are present, they can be sent to new sectors, allowing you to expand your colony.
The game is won when the red ants are eliminated from the play field, and the human and their pets are driven away by the overwhelming ant infestation.
