Each country will propose one or more games: with cards, dice, riddles, matches, boardgames... All students will be invited to play in groups, to observe different situations and then to develop strategies to win. The strategies will be exchanged and explained between the different partners. An afternoon of games should be organized in each college in the form of stands where each student who participated in the project will become a Master of Time and will propose duels as in Fort Boyard.
