Free AI game maker for Roblox: what is free and what is not
You can build, change and export a Roblox game on the Free plan. Here is where the free part stops.
Yes, you can make a Roblox game with AI for free. The PromptBlox Free plan includes Light builds, chat edits and a Roblox Studio export, all within a small weekly usage allowance.
That allowance is the limit that matters. Every build and edit uses some of it, so the Free plan suits small ideas. This page lists what you get, what costs money and what other free tools offer.
What the Free plan includes
The pricing page has the current amounts. These are the parts of the plan and their limits:
| Part of the plan | On Free |
|---|---|
| Build level | Light only. |
| Usage | A small weekly allowance. It resets every Monday at 00:00 UTC, and unused allowance does not roll over. |
| Number of games | No fixed number. Make as many as your allowance covers. |
| Cloud saves | 2 builds saved at once. Editing a saved build does not use another save. |
| Chat edits | Included. They use your allowance too. |
| Saved versions | Included, so you can go back to an earlier version. |
| Export | Included. Download a .rbxlx place file with the world and its scripts. |
| Preview links | Included. Someone can look around the saved world and tell you what they think, but they cannot play it there. |
| Privacy | Projects are private by default. |
| Support | Community support. |
There is one more limit. Free accounts share a capacity limit, so free generation can pause for a while even when your own allowance is not used up. If a chat edit fails because of a problem on our side, the usage it consumed goes back to your current allowance.
Light is the starting build level. Higher levels put more work into the world and the gameplay, and they can use more allowance and take longer. Start a Light build with one world and one main activity, then test it and improve it from there.
What is not free
- Higher build levels. Medium needs Pro or above, High needs Max or above, and Ultra builds need an Ultra or Ultra+ plan. Lite stays on Light with a larger allowance.
- More weekly usage. Paid plans have larger allowances that reset every seven days, even on yearly billing.
- More cloud saves. Paid plans keep more builds saved at once.
- Extra credits. These are one-time packs that are used after your weekly allowance runs out. They never expire, and they do not change your plan or your build levels.
Costs outside PromptBlox
Roblox Studio is a free app for Windows and Mac. Playtesting needs Studio, so plan for time on one of those computers.
New games on Roblox start private. Making one public is a separate step with Roblox’s own rules, including an age check and a content questionnaire. Reaching all ages has further requirements, which can include a Roblox subscription or a refundable fee. Roblox’s publishing guide has the current rules.
How to make a free allowance go further
Start with one small idea
Pick one place and one activity. For example: “Make a small bakery street. Players take a warm loaf from the oven and carry it to one of three doors. Show how many loaves they have delivered.”
Ask for one change at a time
Name what to change and what to keep: “Make the doors easier to see from the oven. Keep the street layout.” A clear edit gives the build a smaller job than a list of ten wishes.
Test before you ask for more
Export the game and play it in Roblox Studio. Then bring back one real problem, such as “The loaf count stays at zero after I reach a door.”
Check your usage meter
The meter in your account shows what you have left and the exact reset time. Check it before you start a larger change.
Other free AI game makers
Most free AI game generators run on credits or a usage limit, ours included. If your game does not need to be on Roblox, these have a free way to start. The details come from each maker’s own pages, as of November 2026. Limits change, so check before you commit.
| Tool | What is free | What it makes |
|---|---|---|
| Rosebud | A Free plan with 8,000 credits that refresh weekly in eligible regions, project limits and no credit card. | Browser games you share by link. |
| Astrocade | Its blog says you can start creating and playing for free. We did not find published limits. | Games for its own gallery. |
| PlayDrop | 50 free credits a day, claimed in Quests. A cloud task costs 100 to 1,000 credits. | Browser games. |
| Replit | A Starter plan with daily Agent credits and one published app, whose link goes down after 30 days. | Browser games with code you can edit. |
| GDevelop | A Free plan with 40 AI requests a month, 3 cloud projects, unlimited gd.games publishing, and 1 desktop and 1 Android publish a day. | Desktop, web and mobile games. |
| Unity | Unity Personal is free with no credit card, within Unity’s revenue and funding limit. Its assistant in the Editor uses credits; Personal users start with a free trial. | Web, desktop and mobile games. |
None of those pages says the tool makes Roblox games. For a Roblox game, start with PromptBlox Free: you describe the game and get a place file to open in Roblox Studio, which is also free and includes Assistant. Our AI game maker guide explains how these tools differ, and starting free in your browser walks through a first project.
For parents
PromptBlox is for users 13 and older, and our Terms ask anyone aged 13 to 18 to have a parent or guardian review them. The Free plan has no payment step. Paid plans and extra credits are separate purchases, processed by Stripe.
Questions about making games for free
Is PromptBlox really free?
Yes. The Free plan costs nothing and includes Light builds, chat edits and a .rbxlx export, within a small weekly usage allowance. Higher build levels and more weekly usage need a paid plan.
How many games can I make for free?
There is no fixed number. Each build and edit uses allowance based on the work it takes, so small games go further. Up to 2 builds stay saved in the cloud at once, and deleting one makes room for another.
What happens when my free allowance runs out?
You keep every game you made. New builds and edits wait for the next reset, on Monday at 00:00 UTC, unless you buy extra credits or choose a paid plan.
Can I export a game I made on the Free plan?
Yes. Exporting the .rbxlx place file is included on every plan. Open it in Roblox Studio, which is free, to playtest the game and make detailed edits.
Do I need an account or a credit card?
You need an account, and you sign in with Google, Discord or Roblox. The Free plan has no payment step. You only pay if you choose a paid plan or buy extra credits.
Can I publish a game from the Free plan to Roblox?
Yes. Your plan does not change how publishing works. You publish from Roblox Studio, or from the Share menu if you have connected a Roblox account, added your own Open Cloud API key and already have a place on Roblox. New games start private, and Roblox’s own requirements apply before a game can go public.
