Roll20 is an online virtual tabletop platform that enables users to play a variety of classic tabletop role-playing games (RPGs) such as Dungeons & Dragons, Pathfinder, Savage Worlds, and others, with friends or strangers. The app provides a set of tools to create characters, manage combat, draw maps, and more. It also provides a virtual library of content that includes official published adventure modules, dynamically lit maps, tokens, artwork, and other tools. Users can collaborate online in real-time using video, voice, and text chat, and access their games from any device. The app also offers virtual table enhancements such as character sheets, an initiative tracker, and a dice roller. With its easy-to-use interface, Roll20 provides a great way for players to manage their games and for game masters to create epic adventures.
