What makes gaming so addictive? With his Gezond Gamen concept, a board game for vmbo students, Rafaël Groznik tries to make that clear. He hopes that this will make young people more aware of the fact that gaming can be addictive. Thursday, Rafaël won de Gouden Meesterproef (Golden Master's thesis), an award for the best graduation thesis. Yesterday he was one of the 73 students who received his diploma at the Graduation Show. A total of 495 students are now graduated from the programme, which exists since 2010.
