7 Wonders

Keep Age cards whose minimum-player requirement does not exceed the player count; add a random selection of player count plus two Guilds to Age III. Choose a Wonder board and its Day or Night side, and start each player with three coins. Shuffle each Age deck and deal seven cards per player when that Age begins. These are the 2020 second-edition base rules for 3–7 players.

Each turn, secretly choose one card and simultaneously use it in exactly one way: pay to construct that Building; pay only the next Wonder-stage cost and place the card face down beneath it; or sell the card for three coins from the reserve. Never build duplicate named structures. Wonder stages are built left to right; the buried card does not provide its printed Building effect, and completing the Wonder is optional.

After all actions, pass remaining cards left in Ages I and III and right in Age II. Normally an Age has six turns. From the final two-card hand, use one and discard the other without a reward; that final discard is not a three-coin sale. Specific Wonder effects can change the last-card procedure.

Pay the cost on the Building or Wonder stage using your own production and any resources bought from neighbors. Production is reusable capacity rather than stock discarded after use, with each symbol supplying one resource that turn. Coin costs go to the reserve. Construction uses coins held at turn start; coins gained during the turn must wait until later turns.

Buy only from immediate left and right neighbors, using their starting resource and Brown or Grey production, normally paying that neighbor two coins per resource before discounts. Yellow and Wonder-stage production is unavailable for sale, as is a structure built that same turn. Neighbors cannot refuse; their own use and the other buyer’s use are not depleted. Each buyer independently selects a flexible resource, and purchases cannot be stored for later turns.

From Age II onward, a matching chain symbol on an existing Building lets you construct the new chained Building without its normal cost. You may still pay normally without the matching symbol. The duplicate-name restriction remains. A chain does not give two uses to one card or waive a Wonder-stage cost.

At each Age’s end, compare total military symbols separately with each neighbor. Ties give neither side a token. A loss gives minus one; a victory gives one, three or five in Ages I, II or III respectively. The game ends after Age III’s military resolution rather than after a sequence of separate player turns.

Add seven scoring categories: Wonder, one point per complete three coins, military tokens, Blue cards, Yellow cards, science and Guilds. Each type of matching science symbol scores its count squared, with seven more per complete set of three different symbols. Apply special effects and chosen science symbols as described. Highest total wins; tied players compare remaining coins, then share victory if still tied.
