It is organized into individual game sessions, which users can create or join. These game sessions include various features of typical tabletop RPGs, including dynamic character sheets, automated dice rolling, shared maps with basic character and enemy tokens, and triggered sound effects, as well as a character creation tool for certain licensed game systems. The interface also includes integrated text chat, voice chat, and video chat, as well as Google Hangouts integration. Roll20 also contains a separate marketplace, where art assets and complete game modules are sold, and a reference compendium for several game systems. Compendiums and game modules published through the marketplace are only available to use on the Roll20 platform, while some art assets and art packs can be transferred to other sites or downloaded and used for physical tabletop sessions. In addition to the free content, Roll20 also has extra features available for paying subscriber accounts, including dynamic lighting and fog of war for maps. Besides the main browser version of Roll20, there are also iPad and Android versions. These mobile versions are more focused on the player experience, containing fewer features than the full browser site.
