Chemline is a card game consisting of 104 cards, corresponding to the first chemical elements. Goal: create lines by placing cards in the order of, either the element's atomic number or, its year of discovery. In doing so, players become familiar with atomic elements and can discover different information about each element. The etymology of each name, the main uses of the elements, their molar masses and their electronegativity can all be found. This is a free game (in French) available from their creators, the ENSCMu – Ecole Nationale Supérieure de Chimie de Mulhouse
