A game of 7 Wonders takes place over 3 Ages, each using one of the 3 card decks (first the Age I cards, then Age II, and finally Age III).

With each age players have the opportunity to play 6 cards develop their city, advance their Wonder and military.

At the end of each Age, each player compares their military might with their two neighboring cities (belonging to the players to their right and left).

At the end of the third Age, the players count their victory points; the player with the most points wins the game.
