Obby — meaning in Roblox
An obby is a Roblox obstacle course: jump, dodge and climb through platforming stages. One of the oldest and most beginner-friendly genres.
Updated:
Obby is short for obstacle course. The recipe is timeless: a chain of stages with jumps, lava floors, moving platforms and checkpoints. Classics like Tower of Hell modernized the formula with no-checkpoint towers and timers.
Obbies are usually the first thing new players try because the rules are obvious and a round takes minutes. Difficulty-chart obbies rank stages from easy to impossible, and speedrunners treat the hardest towers as competitive sport.
