How to get Roblox Build
- Open the Roblox app on your phone and update it.
- Look for the Build tab.
- If it is there, complete Roblox’s age check if you have not already. Build is for accounts aged 9 and older.
- If it is not there, Build has probably not reached your region. Roblox’s guide says to expect a gradual rollout.
What Roblox Build can make
Roblox says Build currently focuses on 2D and 2.5D games and works best with simpler kinds: clickers, arcade games, collect-and-score games and side-scrollers. More kinds of game, including 3D, are planned for later updates.
You describe the game in plain words and then keep refining it in the same chat, for example by asking for bigger coins, a timer or slower enemies. Every message counts as one prompt.
What Roblox Build costs
You get a set number of free prompts each day, and they reset daily. When they run out, you can buy more credits with Robux inside Build. Roblox says purchased credits do not expire, and that a game already being generated finishes before you are asked to buy more.
Publishing, and who can play
When you tap Publish, Roblox runs a short safety check and the game goes live on your profile. Every Build game is set for players aged 16 and older by default. To let younger players in, a creator applies through the Roblox Select process, which includes a content review.
Roblox Build and Roblox Studio
Roblox Studio is the free desktop editor where most Roblox games are made. You can open a Build game there, but Roblox says that editing it in Studio permanently turns that version into a standard Studio game and removes its Build status. If you want to keep changing the game with prompts, make your changes in the Build chat instead.
If Build is not in your country yet, or you want a 3D game
PromptBlox works in a web browser, so it does not depend on the Build rollout. You describe a game, PromptBlox builds a 3D world and the Luau scripts that run it, and you change it in chat. Then you download a place file and open it in Roblox Studio on a Windows or Mac computer to playtest and publish.
| Roblox Build | PromptBlox | |
|---|---|---|
| Where you make the game | The Roblox mobile app | A web browser on a computer, phone, tablet or Chromebook |
| Kind of game | 2D and 2.5D today | 3D worlds with scripted gameplay |
| Publishing | One tap inside the app | Export a place file, then publish from Roblox Studio |
| Do you need a computer? | No | Yes, to playtest and publish in Studio |
| Minimum age | 9, with an age check | 13 |
| Free use | Free prompts each day | A small weekly allowance on the Free plan, with shared capacity limits |
PromptBlox is the way to get a 3D game today. It works in any country, and you get a place file you can keep editing in Studio. Build stays inside the Roblox app, so it can publish without a computer once it reaches you.

After your first Build game
A first Build game teaches you what makes a game fun to repeat. The next step for most creators is a bigger 3D game and Roblox Studio.
