Overview

Deus is a civilization-building card game where players explore unknown lands, found cities, and construct buildings to exploit natural resources, establish trade routes, conquer barbarian villages, and increase scientific knowledge. On each turn, players either construct a building (play a card and place a wooden piece on the map) or make an offering to a god (discard cards for divine aid). The game ends when all barbarian villages are attacked or all temples are built. The player with the most victory points wins.

Components

Setup

  1. Form the gameboard from Continent tiles based on player count: 4 tiles (2 players), 6 tiles (3 players), 7 tiles (4 players). Orient freely but never place 2 barbarian villages adjacent to each other.
  2. Place VP on each barbarian village equal to the number of adjacent regions.
  3. Form general supply: Temples equal to number of Continent tiles, 5 resources of each type per player, VP tokens, gold.
  4. Each player takes 1 player board and Building pieces in their color. Place 2 pieces of each type on the corresponding column of the player board. Remaining pieces form personal supply.
  5. Each player takes 5 gold, 4 resources (1 of each type), and 5 VP.
  6. Shuffle all 96 Building cards, deal 5 to each player, form draw pile.
  7. Choose first player, give First Player card.

Turn Structure

Each round, players take turns clockwise starting with the First Player. On your turn, choose exactly 1 of 2 actions:

A. Construct a Building or B. Make an Offering to the Gods

Actions

A. Construct a Building

Standard Buildings (Civil, Scientific, Maritime, Military, Production)

  1. Verify availability: Must have at least 1 wooden piece of that type on your player board.
  2. Play the card: Place it at the top of the matching color column above your player board (all card effects must remain visible).
  3. Pay construction cost: Shown in upper-left corner. Each resource can be replaced by 4 gold.
  4. Place wooden piece: Move from player board to a region on the gameboard following placement rules:
    • First building must be at the edge of the board. First buildings of different players must be separated by at least 2 empty regions.
    • Subsequent buildings go in a region you control or an empty adjacent region.
    • Each building in a single region must be a different type.
    • Cannot build in barbarian village regions.
    • Maritime buildings (ships) go in sea regions only. Other buildings cannot go in sea regions.
    • You may place in a non-adjacent edge region by paying 3 VP.
  5. Activate card effects: Resolve all cards in that column from bottom to top.

Temples

  1. Place card in temple column on player board.
  2. Prerequisite: 1st temple = free; 2nd temple = need 1 card of each color on player board; 3rd temple = need 2 cards of each color; etc.
  3. Cost: Always 1 of each resource type (each replaceable by 4 gold).
  4. Place a wooden temple from general supply in one of your regions (not empty). Each scores up to 12 VP at game end per its condition.
  5. Can still play a Temple card if supply is empty (just don’t place the piece).

Attacking Barbarian Villages

Happens immediately when both conditions are met:

The player with the most armies adjacent wins the VP on the village. Ties broken by most total buildings adjacent; if still tied, VP split (rounded down).

B. Make an Offering to the Gods

  1. Discard at least 1 card from your hand face-up to the discard pile.
  2. Invoke the god matching the topmost discarded card. Power scales with number of cards discarded.
  3. Draw cards to refill hand to 5. (Max hand size: 10 cards.)
God Color Power
Neptune Blue/Maritime +2 gold per discarded card; +1 wooden maritime building
Ceres Green/Production +1 resource of your choice per discarded card; +1 wooden production building
Minerva Yellow/Scientific +1 wooden scientific building; draw 1 extra card per discarded card in step 4
Vesta Brown/Civil +1 VP for 1 discarded card, +2 VP total for 2+; +1 wooden civil building
Mars Red/Military +1 wooden building of your choice per discarded card
Jupiter Purple/Temple Use the power of any other god (wild)

Note: If you run out of cards in hand, automatically draw 5.
