Stellium is a board game released in 2017 for 2–4 players, 30–60 minutes per game, and ages 10 and up. It was designed by Rémi Saunier and its main mechanics are Modular Board and Pattern Building.
Stellium is a game in which players are architects of the universe just after its creation. They have to draw celestial bodies from a bag (represented by marbles with different textures, so they can try to pick the one they are looking for) and place them on the universe to complete contracts. Each type of celestial body has an effect on the universe, e.g., the comet takes the place of another one and "pushes them in line". —description from the publisher
Stellium 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 Stellium is 30–60 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 Stellium for ages 10 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.
Stellium has a complexity rating of 2.5 out of 5 from BoardGameGeek players, which makes it a medium-light game. The rating reflects how much rules knowledge, planning and decision-making a typical game demands. Expect a longer first teach for heavier games, and use a preparation guide before game night.
Stellium belongs to these categories: Abstract Strategy, Memory, and Space Exploration. Its main mechanics are Modular Board and Pattern Building. Categories describe the theme and setting of a game, while mechanics describe what players actually do on their turns. Each mechanic links to a catalogue hub with similar games, which helps when you want something comparable.
The credited designers of Stellium are: Rémi Saunier. These credits come from the published game data and name the people responsible for the game’s design, not its illustrators or publishers.
