7 Wonders is a modern board game with fast-paced and challenging mechanics in which players take on the role of leaders of major ancient cities, competing for resources, military power, commercial skill, social and technological development, and the opportunity to build their own wonders of the world. A game of 7 Wonders spans three eras, each using a specific deck of cards (first the cards of era I, then those of era II, and finally those of era III). Each era is played similarly, with each player able to use six cards per era to develop their city and build their Wonder.
