In Deus, 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. (boardgamegeek.com)
