National Erasmus Games (former ESNOLYMPICS) is a national ESN project based on the idea of olympic games. Divided in 3 stages: local, national and international. The first stage consists of local level play-offs where the team representing the city is determined. The team consists of 11 players (including at least 2 girls). Then, chosen teams meet at the national final, organised by one of the ESN sections (the last final games happened place at Warsaw from 13-15 April 2018). The team that wins there plays at the international level representing Poland at International Erasmus Games that take place at one of the European cities. The games played are futsal, basketball and volleyball.
