Players work to develop their own civilizations in a shared environment. Each player starts the game with five building cards, and on a turn a player either uses one of these cards to construct a building or discard one or more cards to make an offering to a god. Cards come in six colors: red for military, green for resource production, blue for trade, brown for scoring, purple for temples, and yellow for a variety of effects.
The game ends either when all the barbarian villages on the game board have been surrounded and attacked or when all the temples have been constructed. Whoever has the most points wins.
