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.
- Unique and original mechanics that fit the theme
- Excellent artwork on planets with distinct designs
- Sturdy components and clear, concise rulebook
- Good balance between tactics and strategy within a 5-card hand limit
- Narrative elements on cards and in solar system information enhance immersion
- Replay value per deck is somewhat limited; decks feel small
- Variability across player counts can feel chaotic, reducing sense of control
- Lacks a certain spark or excitement for some players
- Endgame reliance on final evolution cards can create dead hand situations
- Planetary formation, habitability, and endgame scoring through evolution cards
- Space/solar system development and evolution
- Cards and board text provide planetary/solar system narrative context
Mechanics (from transcript analysis)
- Endgame sequencing — Triggering endgame allows the optic player to finish, then others take final turns and score from fulfilled final evolution cards.
- Evolution card deck — Each player draws from an evolution deck; cards have prerequisites and point values, influencing endgame scoring.
- Gravity and discard interactions — Certain icons allow grabbing tokens from anywhere or discarding tokens to draw/complete cards.
- Habitable/hostile determination — Planet type and card totals determine habitable vs hostile status, affecting scoring and strategy.
- Orbital/token movement — Matter tokens and planets move in a defined orbital path; planets can move freely until they encounter a token, with speed increasing during evolution acceleration.
