Italy
participants
Involve the international students in a team challenge game that involves both physical well-being (taking place all over the city) and mental well-being (being carried out right before the beginning of classes).
We gave each team a riddle whose solution is a place in the city (like a building or a monument, which would be visited in the following days of the Erasmus Welcome Days): when they proved us they got the solution by sending us a selfie in that place, they were sent the next riddle. Each solution (which required a run through different places of the city, to arrive before the other teams), gave as result a piece of a geographic coordinate. The 3 teams that solved all the riddles and reached the position given by the coordinates first, were awarded winners and got ESN gadgets as prizes.
