hi Lisa, RPG is role playing games, including Dungeons and Dragons. Traditionally RPGs are played face to face in a room with no digital devices required. However, like most things these days there are now online versions and that is what my son has been using since lockdown etc on Roll20. It is then played online in a similar way as if you were in the same room and talking to each other in roles, in real time. You are following a storyline that can be pre-written or you can create.  Lots of fun I believe, and good social interaction as well as learning opps.
