How to Make anObby in Roblox

What an obby is made of

Every obby, from the simplest to the most elaborate, is built from the same handful of ingredients:

• A spawn/start pad — where players begin and where the first checkpoint usually sits.
• Stages — a sequence of platforms and jumps, ideally getting harder as players progress.
• Checkpoints — pads that save progress so death sends players back a step, not to the start.
• Kill bricks — lava, spikes or hazards that respawn the player at their last checkpoint on touch.
• Obstacles — moving platforms, spinners, disappearing tiles and gaps that make each stage interesting.
• A finish line — the final pad, often with a leaderboard, a badge, or a reward for completing.

The two ways to build an obby

Build an obby step by step with AI

The flow is describe → generate → refine. Lead with the length, the theme and the hazards, then add systems and tune the difficulty in follow-up lines instead of starting over:

The scripts an obby needs (and what they do)

An obby is mostly placing parts, but a few small Luau scripts make it an actual game. An AI builder writes all of these for you; here's what they are so you know what's happening:

• Checkpoint script — when a player touches a checkpoint pad, it saves that stage as their spawn so they respawn there instead of at stage 1.
• Kill-brick script — when a player touches a hazard, it resets their character, sending them back to their last checkpoint.
• Stage/leaderboard script — tracks the highest stage each player has reached and shows it on the in-game leaderboard.
• Timer script (optional) — records completion time for a speedrun leaderboard, the single feature that gives an obby replay value.

How to design an obby that's fun, not frustrating

The difference between an obby people finish and one they rage-quit is design, not difficulty. Keep these in mind:

• Ramp the difficulty — start easy so new players get hooked, then increase the challenge stage by stage.
• Space checkpoints fairly — close enough that a death isn't punishing, far enough that reaching one feels earned. Every 3–5 stages is a good rule.
• Make jumps readable — a player should see where they're meant to land before they leap. Surprise gaps feel cheap.
• Make kill bricks obvious — hazards should look dangerous (lava red, spikes). Invisible or same-colour kill bricks are the fastest way to lose players.
• Keep it finishable — 20–40 stages is plenty for a first obby. A 200-stage marathon nobody completes is worse than a tight course they beat and replay.
• Add a theme — candy, lava, space, neon. A visual identity makes an obby memorable and screenshot-worthy, which is what earns plays on Roblox.

Common obby mistakes to avoid

Most bad obbies fail the same few ways. Steer clear of these:

• Impossible jumps — a jump that requires pixel-perfect timing every time isn't hard, it's broken. Playtest every jump yourself.
• No checkpoints — sending players to stage 1 on every death guarantees they quit. Checkpoints are non-negotiable.
• Too long, too soon — an endless course with no payoff loses players by the middle. Ship a tight one and extend it later.
• Hidden kill bricks — hazards players can't see feel unfair. Telegraph every danger.
• No reason to finish — add a finish reward, a badge or a leaderboard so completing the obby means something.
