Zero-Sum app for iPhone and iPad

Zero-Sum is a complex macro-economics card game for multiple players. Each player runs a country and sets financial priorities, which are then played out on a global stage with or against the other players.

A valid macro-economics model underpins the game, driven by the card choices of the players. Players can also alter the economic model to suit their beliefs or preferences.

Players can choose to go for a competitive win (financial trade balance), or a “Economic Fairness” win (those in power are responsible for providing opportunity for those less fortunate — low unemployment and low wealth gap), or an “Industry” win, or a “Standard of Living” win (low cost of living with high consumer spend). Is it possible to achieve more than one?

Play to win or play cooperatively to see how long you can keep every country solvent.
