Dobble environnemental - Colegiul National Emil Racovita (Cluj - Roumanie) Lycée Val de Durance (Pertuis) Lycée Bellevue (Alès) Colegiul National Mihail Eminescu (Satu Mare - Roumanie)

In this article, we have included the aspects we have been following during our research: How is the game built? How many symbols do you need to make a 10-card set? Or conversely, how many cards for a 10-symbol game? Can you make a Dobble game with environment-related symbols? Find a relationship between the number of cards and the number of symbols. How does this relationship change if two cards have two, three, etc… symbols in common?
