ABOUT THE GAME

From big cats and whales, to mosses and butterflies: How are Earth’s species really doing? The answers may surprise you. In Biodiversity Call, the players get to explore how different species groups are coping and what threatens their survival. Fast-paced, visual, and grounded in real research, the game reveals the hidden patterns behind global biodiversity loss, and best of all; the rules are so easy that it just takes a minute to get started.

The game is perfect for classrooms, families, and anyone curious about the state of the natural world. At work, it’s a great conversation starter!

Biodiversity Call was created in collaboration with Biodiversity and Ecosystem services in a Changing Climate (BECC); a strategic research area that engages about 350 researchers at Lund University and the University of Gothenburg.

Biodiversity Call is published by Klimatkoll Guldheden AB in Sweden.

HELP US IMPROVE THE GAME

Biodiversity Call is still under development. A demo version (which you might already have in your hand) has been printed and handed out at the Swedish Biodiversity Symposium, 21-23 Oct 2025. Together with the BECC research network, we are now fine-tuning this demo version. The final version will be sent to print on November 15. 

  

EXPLORE BECC RESEARCH

The game includes 9 multiple-choice questions that highlight BECC research and how human actions affect biodiversity and climate change. Questions are designed to spark discussions — from “Which pollinators increase harvests most?” to “What happens when peatlands are drained?”.

The question cards are used at the beginning of each round.

Curious to know more?

We’ve built an AI chatbot trained on BECC research. Use it to explore the studies behind the question cards, ask your own questions, and discover how human activities shape biodiversity and ecosystems! 

HOW IS BIODIVERSITY CALL PLAYED?

One round takes about 15 minutes and is played by two teams of 1–3 players per team. The game is suitable for players 12 years and older. 

The aim of the game is to sort species groups in the correct order — from least to most threatened. The percentage printed on the cards show how many species in that group are considered threatened (Vulnerable, Endangered, or Critically Endangered) according to the IUCN Red List. The threat levels (1–5) are our way of grouping the percentages into simpler categories for the game.    

Each round also includes a quiz question that illustrates the links between human action, effects on biodiversity and climate change.

Biodiversity call, the row of threathened species.

PREPARE

1. Play individually or in two teams. Place three cards in a row, face up (the colorful side), in front of each team. The remaining cards are placed in a pile on the side.

2. Place two cards, face down, to start the row of threatened species groups. Players will place their cards here in order from the least (1) to the most threatened group (5).

3. Draw a Question card, read it, and let the other team answer. Correct? Nothing happens. Wrong? They must draw another game card and hence start with 4 cards.

How to play Biodiversity Call

PLAY 

One team starts by guessing where one of their cards belongs on the row of threatened species groups. Turn it over and reveal its threat level (1–5). 

Correct? The card stays in the row of species groups. The turn passes to the next team.

Wrong? The card is set aside. The team draws a new card. The turn passes to the other team.

The first team to get rid of all their cards wins! 

Note! Cards only need to be ordered by threat level and not percentages. The numbers do not need to be placed in sequence – a 5 can be placed directly after a 3 if there is no 4.

Want to try a more challenging version? Try playing by the exact percentages!

A step-by-step teacher’s guide and a series of exercises for the classroom are under development. Check in again in a few months to take part of educational materials for teachers!

Distribution of games to teachers 

During spring of 2026, thousands of games will be distributed to classrooms all over Sweden, as well as to Swedish Naturrum centers (visitor centers for nature and outdoor education located in national parks and protected areasand botanical gardens worldwide. The games will be accompanied by a step-by-step teacher’s guide and a series of school exercises designed to make learning about biodiversity, ecology, and ecosystems both engaging and inspiring. 

HELP BIODIVERSITY!

When playing Biodiversity Call, you may realize that far too many species are under pressure — from climate change, pollution, over exploitation, habitat destruction, and other threaths. And you might ask yourself: What can I do to help nature thrive, and what should I avoid doing?
