Bruno Cathala and Antoine Bauza have released a solo mode for their popular two-player game 7 Wonders Duel. The Print and Play file contains five Leader cards, from which you can choose your opponent, and twelve Decision cards that you put in a deck to let these Leaders take random actions on their turn. All Leaders have their own specialisation. For example, Ceasar starts out with the Strategy Progress token and goes for the guilds, while Cleopatra has both the Philosophy and the Agriculture Progress tokens and aims for civilian buildings. So you'll have to adapt to your opponent.
At the start of the game you hand out two Wonder cards to the opposing leader. They are considered constructed, some effects are resolved (and Victory Points for them will be counted at the end of the game if it comes to that). You'll start with four Wonders to try and construct.
On the Leader's turn a card from the Decision deck is drawn. It shows the priority in which the Leader will try to acquire one of the available cards. Also, if a symbol on this card matches the one on the Leader card, the Leader will take another turn. Gameplay on your own turn is as usual, the end conditions remain the same as well.
The Print and Play files can be downloaded from the Asmodee website.
