Special rule: You can choose to construct the stages of the Great Wall in any order.

- Day:

Stage 1: When this Wonder stage is constructed, immediately take 8 Coins (from the reserve) and add them to your Treasure.

Stage 2: At the end of the game, choose 1 science symbol to gain and add it to your collection of Green cards.

Stage 3 : As soon as this Wonder stage is constructed, increase your military strength by 2.

Stage 4 : At the end of the turn when this Wonder stage is constructed, take all of the cards in the discard. Choose one and construct it for free.

- Night:

Stage 1: When this Wonder stage is constructed, immediately gain 8 Coins (from the reserve). Your neighbors immediately gain 2 Coins each.

Stage 2: At the end of the game, gain 1 science symbol that is on a Green card in one of your neighbors’ Cities. Clarification: You can gain and apply this symbol multiple times (with cards from the Cities expansion). However, you cannot choose to gain the science symbol on a single card multiple times by neighbors.

Stage 3: At the end of the turn when this Wonder stage is constructed, all players except you lose 2 Coins. These Coins are returned to the reserve. When this Wonder stage is constructed, immediately take one Diplomacy token (from the reserve) and place it on your Wonder board.

Stage 4: As soon as this Wonder stage is constructed, once per turn, produce one resource (your choice) from the ones you do not produce from your Brown, Grey cards, as well as your Wonder’s starting resource. Clarification: Resources produced by Yellow, Black, Island and Leader cards do not apply for this effect.
