On each turn of World's Fair 1893, the active player sends a supporter to one of the five areas and gather all of the cards by it. New cards are then added to some of the areas, and the next player akes a turn.
The five areas represent sections of exhibits, like Fine Arts and Electricity. Some cards represent exhibit proposals in one of those five areas, others represent influential people who give you bonus supporters, and other cards represent tickets for attractions and concessions along the Midway.
The game consists of three scoring rounds, each triggered when players collectively gather a certain number of Midway tickets. Players gain reputation points for leading in number of supporters in an area and for gathering the most tickets in each round. The leaders in an area also receive approval for exhibit proposals they have gathered that match the area. Players gain reputation points at the end of the game based on the breadth and diversity of their approved exhibits.
