How can digital twins help us anticipate environmental changes and make informed decisions? To make these concepts accessible to a wider audience, the JUNON programme developed Double Jeu, a board game that introduces players to how environmental digital twins work.
One territory, two game boards
In Double Jeu, players are responsible for managing a territory made up of towns, villages, agricultural areas and industrial zones, all of which rely, to varying degrees, on groundwater resources.
The game uses two complementary boards: one represents the real-world territory, while the other represents its digital twin.
During each turn, players face different events, such as droughts, heavy rainfall or water extraction. They must use forecasts generated by the digital twin to anticipate the consequences and choose the most appropriate adaptation measures.
Through this gameplay, participants explore the key stages of how a digital twin works: collecting data from the real world, simulating future conditions, making decisions and updating the digital twin based on what actually happens.

A tool for science communication
Designed to make digital twins easier to understand through hands-on learning, Double Jeu was developed in collaboration with Arkham Studio, which designed and developed the game mechanics based on scientific concepts, guidance and feedback provided by the JUNON team.
First presented at the 2026 Fête de la science (French Science Festival) hosted by BRGM in Orléans, the game offers an engaging way to explore the challenges of water resource management and demonstrate how digital tools can help us better understand and manage our environment.
