Dungeons & Dragons
Dungeons & Dragons (D&D), currently in its 5th edition, is the oldest and most recognised tabletop roleplaying game.
Dungeons & Dragons is a fantasy game. Characters - who may be human or a fantasy race such as Elf or dwarf - are assigned classes, including fighter, rogue, wizard and cleric, representing their role in the game. As characters progress in the game they earn experience, which earns higher levels, improving their abilities. The game uses polyhedral dice as randomisers.
Dungeons & Dragons has a complex publication history, with the original version of the game spawning two successors (Basic and Advanced D&D). Although the current version of the game is known as the 5th Edition, there have been more than 5 editions of the rules.
The first edition, usually known as Original Dungeons & Dragons (OD&D) was designed by Gary Gygax and Dave Arneson, and published by TSR in 1974. It was based in part on Gygax's earlier fantasy miniatures wargame Chainmail. Wizards of the Coast, the current publishers, released a premium reprint of the first edition and its supplements in 2013.
