Question: How do I play?
Game: 7 Wonders (2nd Edition) (edition bg-316377-en-2e)

Ruling:
1. Separate the Age cards into three decks: Age I, Age II, and Age III.
2. Each player randomly takes a Wonder Board, picking their preferred side (Day or Night).
3. For each Age, sort the cards by the minimum number of players required and keep only the cards with a number less than or equal to the number of players.
4. In the Age III deck, take all the Purple cards, randomly draw as many cards from these as the number of players +2, and add them to the other Age III cards.
5. Shuffle each deck of Age cards and put them face down in the middle of the table.
6. Take 3 Coins (worth 1) and place them on your Wonder board.
7. Place leftover Coins and all Military Conflict tokens in the middle of the table to create reserves.
8. At the start of each Age, randomly deal 7 cards to each player face down to make a starting hand.
9. Each Age consists of 6 turns where players play simultaneously.
10. A turn follows these three stages in order:
a. Choose 1 card from your hand and place it face down in front of you, setting remaining cards aside.
b. When everyone has chosen a card, play them simultaneously to complete one single action: Construct the Building on your card, Construct a stage of your Wonder, or Sell the card.
c. When all players have completed their action, take the cards you did not choose and give them to the neighbor on your left (during Ages I and III) or to the neighbor on your right (during Age II), receiving a new hand from that neighbor.
11. At the start of the sixth and last turn of each Age, receive a hand of 2 cards from your neighbor, choose 1, and discard the other face down.
12. Play the sixth and last card as normal and continue to the Resolution of Military Conflicts.
13. At the end of each Age, head to war with your two neighbors.
14. The game plays over three successive rounds (Age I, Age II, then Age III).
15. At the close of 3 Ages, count total victory points from your City, Wonder, military prowess, and Treasure; the player with the highest score wins.
