A TTRPG is, broadly, a co-op game played with a group. Usually, a Game Master (GM) or Dungeon Master (DM) runs the game, while a group of players participate. Most TTRPGs have a set of core rules that everyone agrees to. With the guidance of the GM, these rules keep the game running smoothly. Sometimes referred to as pen-and-paper games, TTRPGs have their roots in filling out a physical character sheet and playing around a table. Many tabletop games utilize accessories such as dice, cards, miniatures, and battle maps. Presently, tabletop roleplaying games are played in-person or online with the aid of chat applications and virtual tabletop (VTT) software.
