Roblox players use “obby” for an obstacle-course style game.
The word is a shortened form of “obstacle course.” In an obby, players typically jump across platforms, avoid hazards, navigate timed sections, and reach a finish point. Roblox’s own Creator Hub uses “Classic Obby” as a beginner template for building this kind of experience.
Obbies became one of Roblox’s recognizable game formats because Roblox Studio makes platform-based challenges relatively easy to build and publish. Some are simple beginner courses, while others add checkpoints, moving platforms, traps, puzzles, timers, or competitive leaderboards.
“Parkour” is a common mix-up because many obbies involve jumping and maneuvering. However, parkour describes a movement style or theme; “obby” is the Roblox community’s standard label for the obstacle-course game format. The term is also used occasionally outside Roblox for similar platforming challenges.
