Biomos is a board game released in 2023 for 1–4 players, 20 minutes per game, and ages 8 and up. It was designed by Gricha German and its main mechanics are Pattern Building, Open Drafting, and Contracts.
Biomos is a 1-4 player cozy and addictive puzzle game about developing new planets. As your planet reaches its first billion years, you will take on the universe’s greatest challenge: creating life. Choose and place terrain tokens on your planet to create stunning landscapes. Combine terrain like oceans, forests, and mountains to match specific biome conditions and foster new life on its surface. Including three ways to play, Biomos features a Family mode for newer players and a Solo mode for an individual challenge. Whatever mode you choose, you will always work towards the same goal: Developing the most biodiverse planet!
Biomos 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 Biomos is 20 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 Biomos for ages 8 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.
Biomos has a complexity rating of 1.3 out of 5 from BoardGameGeek players, which makes it a 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.
Biomos belongs to these categories: Science Fiction and Environmental. Its main mechanics are Pattern Building, Open Drafting, and Contracts. 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 Biomos are: Gricha German. These credits come from the published game data and name the people responsible for the game’s design, not its illustrators or publishers.

The catalogue lists Biomos as a base game. It can be played on its own with the components in the box and does not require any other title. Expansions, if any exist, add new content or rules on top of it and are listed separately in the catalogue with a link back to this base game.
