Biotopes is a board game released in 2023 for 1–5 players, 45–90 minutes per game, and ages 12 and up. It was designed by Sébastien Castano and its main mechanics are Variable Set-up, End Game Bonuses, and Modular Board.
In Biotopes you will have to develop your ecosystem so that it to be as vibrant as possible. Colonize the central landscape, attract animal species and increase their populations. A game of Biotopes is played in 5 or 6 Cycles depending on the chosen game mode. At the beginning of the game, you determine common sources of victory points. --These are the environmental conditions with which your ecosystems will have to deal in order to thrive.-- At the beginning of each cycle, you will draw cubes of four different colors from your bag and place them on the Biotope cards of those colors. --This represents the organic matter extracted from your soil by the plants in your Ecosystem.-- During the cycle you will take turns colonizing the central board and developing and optimizing your ecosystem. --The central board represents the landscape at a macro level in which the different ecosystems spread out and confront each other. Your board and cards represent your ecosystem at a micro level.-- Your actions on the central board will allow you to expand, move your territories and even take territories from your opponents. Your actions in your ecosystem will allow you to play animal species cards, feed them by transferring the resources produced by your plants and make them reproduce in order to make your ecosystem prosper. Finally, to best optimize your future cycles, you will need to draw new cards to deal with new situations. --The cubes on your animal species cards represent the population of that species in your ecosystem.-- Once you and your opponents have exhausted your options, the current cycle will end and you will start a new one. All the organic matter of your ecosystem used during this cycle will be put back in your bag, so it will be used again by your plants for the next cycle. Once all the cycles have been played, you can determine who wins the game by adding up all the victory points: --But be careful, if you have no more cubes on species cards, their populations will die out and they will not be taken into account for the calculation of victory points. Finally, beware of your distribution in the central landscape, a fragmented ecosystem is much less optimal and can grant malus.--
Biotopes supports 1–5 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 Biotopes is 45–90 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 Biotopes for ages 12 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.
Biotopes has a complexity rating of 3.1 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.
