At its core an obby is a start pad, a run of platforms and jumps that get harder as you go, checkpoints so players don't restart from zero, kill bricks that send them back a checkpoint, and a finish line. Building one by hand means placing every platform in Roblox Studio and writing Luau for the checkpoints, kill bricks and leaderboard. The faster route is to describe the obby to an AI builder, which lays out the stages and writes those scripts for you, then refine it by chatting. This guide covers what an obby is made of, both build paths, the scripts it needs, and how to design one that's fun instead of frustrating.
You describe the game. Roblox AI builds the world, writes the Luau, and wires the systems — a complete, playable place, generated in minutes.
How it works
One prompt.
Type your game idea in plain English — the genre, the map, the rules. No coding required — the AI writes all the Luau for you.
The AI plans the build, writes the Luau scripts, places the parts and assembles a playable place file in minutes.
Open it in Roblox Studio or publish it, then keep chatting to add features, tweak balance and ship updates.
PlayableWhat it builds
Any game.
Every obby, from the simplest to the most elaborate, is built from the same handful of ingredients:
There are two honest ways to make an obby, and they suit different people.
By hand in Roblox Studio. You place each platform, colour the kill bricks, and write Luau scripts for the checkpoint system, the kill bricks and the leaderboard. This gives you total control over every jump, and it's how experienced Roblox developers work — but expect to follow tutorials for the scripting parts, which is where most beginners get stuck.
Describe it to an AI builder. Instead of placing parts and writing code, you write what you want in plain English — the number of stages, the theme, the hazards — and an AI lays out the course and writes the checkpoint, kill-brick and leaderboard scripts for you. You get a playable obby in minutes, refine it with one more sentence, and can open the place file in Studio later to hand-tune any jump. The rest of this guide uses this as the main path.
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:
Prompt
Make an obby with 15 stages over a lava void, platforms that get smaller and farther apart as you climb.
Prompt
Add a checkpoint every 5 stages, kill bricks on the lava, and a leaderboard for fastest finish time.
Prompt
Make stages 10 to 15 harder with moving platforms, and add a shortcut path for expert players.
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:
The difference between an obby people finish and one they rage-quit is design, not difficulty. Keep these in mind:
Most bad obbies fail the same few ways. Steer clear of these:
Start free with monthly credits. Go Pro for more credits and faster builds — one generation or refine is about one credit, and bigger builds use a little more.

Lay out a course of platforms with a start and a finish, then add checkpoints, kill bricks and a leaderboard. You can build it by hand in Roblox Studio and script those systems in Luau, or describe the obby to an AI builder that lays out the stages and writes the scripts for you, then publish it to Roblox.
No. The platforms are just placed parts, and the checkpoint, kill-brick and leaderboard scripts can be written for you by an AI builder from a plain-English description. You'd only need Luau if you later want to hand-edit those scripts in Roblox Studio.
For a first obby, 20 to 40 stages is a good target — long enough to feel like a real game, short enough that players actually finish it. Focus on a smooth difficulty ramp and fair checkpoints rather than sheer length.
A checkpoint is a pad that, when touched, saves that stage as the player's spawn point so they respawn there after a fall. An AI builder adds the checkpoint script automatically; in Studio you place a checkpoint part per stage and write a Touched handler that updates the player's spawn.
