game information

Diplomacy is a strategy board game set in 1914 Europe. The board is divided into 56 land areas and 19 ocean areas. Among them, 42 land areas are divided among the seven major countries in the game. Austria-Hungary, Great Britain, France, Germany, Italy, Russia and Turkey. The remaining 14 land areas are neutral at the start of the game.

Each great power controls some regions and some units. The number of controlled units depends on the number of controlled key areas, called Supply Centers (SCs). Simply put, more supply hubs means more units. The goal of the game is to control more than half of all SC by moving units into these areas and convincing other players to support you.
