SIDE A

At the end of the game, the player gains an extra scientific symbol of their choice.

Clarification: the choice of symbol is made at the end of the game, when counting victory points, and not when this stage of the Wonder is built

SIDE B

The first stage is worth 3 victory points.

The second stage gives the player the option of playing their seventh Age card instead of discarding it. This card can be played by paying its costs, discarded to earn 3 coins or used in the building of the third phase of the Wonder.

The third stage grants the player a scientific symbol of their choice.

Clarification:

During the sixth turn, the player can therefore play both cards they have in hand. If the second stage of the Wonder is not built, the Babylon player can then build it on their sixth turn and then play the seventh card instead of discarding it.

The choice of the symbol is made at the end of the game and not on the turn in which the stage of the Wonder is built.
