Iberia

The standard game is cooperative for two to five players. Prepare Player and Epidemic cards for the player count and difficulty, assign a special role to each player, and infect the initial nine cities as instructed.

Take turns performing up to four actions, drawing two Player cards and resolving epidemics, then revealing Infection cards one at a time at the current infection rate.

Carriage or boat movement follows one connected brown line. A train follows a continuous railway, while ship movement between ports costs a City card matching the destination color.

Build Railroad places a railway token on a solid line out of your current city, never on a dashed line. Railways are shared, and their supply is limited.

Discard the City card matching your current city to build its matching-color hospital there. Only one hospital of each color exists, so relocate it if that hospital is already on the board.

Ordinary treatment removes one disease cube from your city. Sharing Knowledge requires consenting players in the same city, normally exchanging the card matching that city; role abilities can alter general rules.

At a hospital city, discard five City cards matching the hospital color to research that disease. It continues infecting cities and does not acquire the original game's cured or eradicated status.

Purify Water discards a card matching a city color in an adjacent region to place two tokens there. A researched disease color can fund any adjacent region. Each token prevents one incoming cube in an adjacent city.

An Epidemic increases the infection rate, resolves the bottom Infection card, then shuffles the Infection discard pile onto the Infection deck. Do not replace Epidemic draws; the hand limit is seven at all times.

Win immediately upon researching all four diseases. Lose on the eighth outbreak, inability to supply required cubes of a color, or inability to draw two Player cards after actions.
