Planetarium is a board game released in 2017 for 1–4 players, 45 minutes per game, and ages 10 and up. It was designed by Dann May and Stéphane Vachon and its main mechanics are Hand Management, Set Collection, and Point to Point Movement.
Matter swirls around a new born star, coalescing on the planetoids that orbit it. Planets evolve, grow and migrate in their orbits, forming a unique solar system by the end of every game. Planetarium is a game of creation, chaos and terraforming on the grandest scale. Players are competing to crash combinations of elements onto planets that then allow them to play cards to evolve the planets in a variety of ways, with each player looking to evolve planets in the system to suit their own secret endgame goals. On a turn a player will firstly move a matter or planet token in a clockwise direction around the star. The board is mapped with a series of lines, tracing orbits around the star, and it is along these lines that the tokens are moved. If a matter token moves onto a space occupied by planet token then the matter token is placed on the player's mat (on the respective planet). In the same way, planets can also be moved onto matter tokens, placing the matter tokens on the player's mat. In the second part of a turn a player can play Evolution cards from their hand at the cost of the matter tokens they have collected on their player mat (some cards have other special requirements to play). If a player plays a card, they score the cards points and check to see if their card has changed the state of the planet from hostile to habitable by checking the total habitable and hostile points played to the planet (some end game goals require planets to be hostile or habitable). The player may then draw a card from one of three decks, Low Evolution (cards that score less points but require less matter to play), High Evolution (cards that score more and are harder to play), and Final Evolution (cards that can only be played on a player's final turn). The thematics of the game have been developed with an eye on the science, led by a scientist working on NASA's search for life on Mars. Evolution cards thematically include all kinds of planetary phenomenon, from asteroid impacts, atmospheric effects, to geological events. Final Evolution cards mark the relatively stable state a planet is in at the end of the solar system's development and include classifications for the final planets such as Hot Jupiter or an uninhabitable frozen dwarf planet. The game consists of a beautiful game board with handfuls of matter tokens, approximately 36 Evolution cards and 16 Final Evolution cards (all with unique space art and flavor), player mats, and player and score markers.
Planetarium supports 1–4 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 Planetarium is 45 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 Planetarium 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.
Planetarium has a complexity rating of 2.1 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.
