Young people participate in esports in many ways and esports activities and initiatives are organised very differently across the world. The purpose of the European Grassroots Esports project is to enable local sports clubs and schools to reach out to young esports practitioners and gamers and include them in value-driven communities that provide them with a chance to meet, play and learn how to live balanced and physically active lifestyles. We aim to inspire future leaders to promote grassroots esports as a “third way" between commercialised esports and individual gaming culture. In this report, we identify and outline different conceptual models and dimensions of grassroots esports and to give perspectives on how to promote grassroots esports where the focus is solely on participating, socialising and enjoying esports and gaming activities. Five approaches to organising esports and gaming are described and three models are presented. This document is an output of Work Package 2 of https://esports.isca.org/
