To give the Erasmus students a virtual tour of Thessaloniki by having them solve fun riddles.
We made a google doc where we shared our ideas about places worth visiting in Thessaloniki. Those would range from historical monuments to parks. We included 25 of the 27 places proposed. For each place, we wrote a small riddle, that would give the participants some information about it, as well as ask them to find some other facts on their own. We purposely asked for pictures on each riddle so the Erasmus students would maybe get inspired to visit the sites. After we finished writing the riddles we gathered everything neatly in a google form that the participants were asked to fill within 2 hours, either by themselves or with a team of up to 5 people. We also gave the option to those whose team was smaller than 5 people to merge with another appropriately sized team.
On the day of the event, organizers and participants alike, joined a google meet call and were split into breakout rooms. Each breakout room contained a team of Erasmus students and an organizer who would act as coordinator and possibly help with some riddles. The host of the meet would stay on the main call and occasionally visit the breakout rooms to troubleshoot and ensure that everything was going smoothly. We asked the organizers on each breakout room to tally up the score of their team (each correct answer was worth 1 point, except for some bonus-hard-questions that were worth 2) while they were completing the form, to avoid any unnecessary delays in announcing the winner. Once every team was finished we announced the winner and that signaled the end of the event.
