At the beginning of the game, the architect draws 3 Construction cards.
He then chooses two of the three cards, one for its number, and one for its effect.
Discard the remaining card.
A player can always refer to the corners of the card on its number side, as it displays the effect from the reverse side of the card.
Perform actions using the two cards as you would in the multiplayer game, discarding after playing them.
Begin a new round by drawing 3 new cards and repeat.
When the Solo card is drawn, all Plans are considered "approved" and it is no longer possible to achieve the higher score.
Turn over the Plan cards to their "approved" side.
All other rules from the classic game remain the same.
