Conspiracy: Abyss Universe is a board game released in 2019 for 2–4 players, 30 minutes per game, and ages 8 and up. It was designed by Bruno Cathala and Charles Chevallier and its main mechanics are Set Collection, Tile Placement, and Pattern Building.
Conspiracy: Abyss Universe is a card game set in the world of Abyss. The card deck in the game consists of cards in five colors, with twelve of each color and cards numbered 0–6. Each player in the game drafts cards and builds a reverse pyramid, starting with a row of five cards, then placing four cards in a row below that, then three under that, etc. On a turn, you can draw 1–3 cards from the deck, choose one of those cards and add it to your current row, then place any remaining cards grouped by color near the deck; alternatively, you can pick up all the cards of a color next to the deck and add them to your current row. As soon as the cards in your rows show two matching keys or three different keys, you take either the revealed location card or the top card of the location deck, and place it on the lattermost card with a key. Location cards increase the value of a card and sometimes have special powers. Some cards feature pearls, and when you have as many or more pearls as whoever has the pearl majority card, you take this card from them. The game ends as soon as someone finishes their pyramid, then all players score their points. For each color, you score points equal to the largest valued card in your pyramid. Additionally, for each color, you look at the largest grouping of cards in your pyramid and you score 3 points for each of those cards. Whoever held the pearl majority card at game's end scores 5 points for it. Whoever has the highest score wins.
Conspiracy: Abyss Universe supports 2–4 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for Conspiracy: Abyss Universe is 30 minutes. This is the publisher’s estimate for a full game. The actual duration depends on the group, the player count and familiarity with the rules: first sessions usually run longer, while experienced groups often finish faster. Setup and teaching time are not included in this estimate.
The catalogue lists Conspiracy: Abyss Universe for ages 8 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone. Younger players can often join with help from an adult, so check the age guidance on your edition and consider your group’s experience with board games.
Conspiracy: Abyss Universe has a complexity rating of 1.8 out of 5 from BoardGameGeek players, which makes it a light game.
