Roguelike is a style of role-playing game traditionally characterized by a dungeon crawl through procedurally generated levels, turn-based gameplay, grid-based movement, and permanent death of the player character. Most roguelikes are based on a high fantasy narrative, reflecting their influence from tabletop role-playing games such as Dungeons & Dragons.

A dungeon crawl is a type of scenario in fantasy role-playing games (RPGs) in which heroes navigate a labyrinth environment, battling various monsters, avoiding traps, solving puzzles, and looting any treasure they may find. Video games and board games which predominantly feature dungeon crawl elements are considered to be a genre.
