Overview

Carpe Diem is a tile-drafting and city-building game set in ancient Rome. Players are wealthy patricians improving their city districts by selecting building tiles from a central display and placing them into a personal building board. The game runs four phases of seven rounds each, with scoring after each phase. Completed buildings and landscapes provide immediate bonuses, and scoring cards determine how points are earned. The player with the most victory points wins.

Components

Setup

  1. Place game board centrally. Each player assembles a frame from 4 random parts, places a random building board inside (shovel pointing toward them), and covers 9 banderole spaces.
  2. Prepare scoring cards by player count and place face-up on card spaces.
  3. Each player places their meeple on an unoccupied semicircular space on the game board.
  4. Place 4 light green tiles on each of the 7 large blueprint spaces (28 tiles total). Place 1 dark green tile on each of the 11 seal spaces.
  5. Shuffle fountain cards into a face-down pile.
  6. Starting player gets 8 VP; subsequent players get 9, 10, 11 VP (special: in 3-player, third player gets 13).

Turn Structure

The game has 4 phases of 7 rounds each. After each phase, there is a scoring period.

Each Round:

  1. Move your meeple to one of the two opposite semicircular spaces (connected by black lines). You must move; you cannot stay.
  2. Pick one building tile from the adjacent blueprint space.
  3. Immediately place the tile in your district following building rules.

Scoring / Victory Conditions

After each phase, players score in order of banderole bar progress (highest first). Each player places a disc on an empty circle space, triggering both adjacent scoring cards.

Scoring card types:

Type details: A cards = pay same wares; B cards = pay different wares; C cards = villa-related; D cards = landscape/dwelling/market related.

Bread shortcut: Pay 3 bread to fulfill any scoring card’s requirements without actually meeting them.

End of game (after 4th scoring): Final scoring for completed villas, fountain cards, and remaining resources.

Most VP wins. Tiebreaker: highest position on banderole bar.
