Micro Cosmos is a board game released in 2023 for 1–4 players, 40–90 minutes per game, and ages 10 and up. It was designed by Michał Jagodziński and Kamil Langie and its main mechanics are Hand Management, Area Movement, and Solo / Solitaire Game.
Micro Cosmos is a 1-4 player, card based, resource management game in which players try to terraform planets, create colonies and bring back survivors to their home worlds. On each turn players move their spaceship (Ark), use their cards in one of 3 different ways in order to gain and convert resources and perform various actions on planets, moons and space stations. Players try to gain victory points by terraforming planets, scouting for survivors, settling them on their home worlds and creating colonies on planets they visit. Once a set number of planets is fully terraformed, the player with the most victory points is considered the winner. The game includes a robust solo mode that uses a super simple Automa deck to perform the AI players actions. Various levels of difficulty create a challenge for any player.
Micro Cosmos 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 Micro Cosmos is 40–90 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 Micro Cosmos 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.
Micro Cosmos has a complexity rating of 2.9 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.
