Galileo Galilei: Luna is an expansion for Galileo Galilei released in 2025 for 1–4 players, 60 minutes per game, and ages 13 and up. It was designed by Tomáš Holek and Michal Peichl and its main mechanics are Variable Player Powers, Area Majority / Influence, and Variable Set-up.
In the 16th century, astronomers like Tycho Brahe studied the Moon’s movements and phases using precise measurements and simple instruments. Galileo Galilei’s telescope revealed craters and mountains on the Moon, thereby disproving the ancient hypothesis of its perfect smoothness. These observations changed our understanding of the Moon and of the entire universe. This expansion for Galileo Galilei introduces the Moon as a new object of observation, adding a new scoring mechanic to explore. Discover four new playable characters, each bringing unique abilities. Additionally, powerful inquisitors enter the game, offering great rewards to those who can successfully persuade them. Map the Moon together and enhance your strategic possibilities! —description from the publisher
Galileo Galilei: Luna 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 Galileo Galilei: Luna is 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 Galileo Galilei: Luna for ages 13 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.
Galileo Galilei: Luna has a complexity rating of 3.0 out of 5 from BoardGameGeek players, which makes it a medium-weight 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.
