Before opening Build

RDC now announces a desktop expansion alongside mobile creation. That does not change the Android age, age-check and region checks below. See the RDC record for the newly announced controls.

Android remains in Roblox’s current eligibility checklist alongside iOS mobile devices. Support names New Zealand, Serbia and Singapore in initial testing. Its Availability paragraph also mentions Mac desktops, but the same page’s eligibility checklist omits Mac; the PC/Mac status explains that conflict.

Check all four access conditions:

  1. Use an Android mobile device.
  2. Confirm Build is available in the account’s region using the current availability guide.
  3. Confirm the account holder is age 9 or older.
  4. Complete the required age check.

Then fully close and reopen the Roblox app. Build appears as a tab inside the app when the account and device have access.

If every requirement appears correct but the tab is absent, continue with the missing Build tab checklist.

Start a first project

Open Build and describe one simple game loop. For example: a small arena where the player collects energy cells before a timer ends, with a visible score and a restart button. Keep the first request narrow, playtest it and add one change at a time.

The step-by-step creation guide covers the full flow, while the prompt guide helps structure a clearer request.

Device claims to avoid

Roblox has not published a Build-specific minimum Android version, RAM requirement, chipset list or complete supported-device table on the current Support page. Do not treat a third-party device list as an official requirement.

Common problems

  • Build is absent on Android: check region and age-check eligibility before assuming a device bug.
  • Generation pauses: Roblox Support recommends typing please continue.
  • AI usage is empty: playing is still allowed; AI changes resume after reset or an eligible Robux top-up.
  • A project is ready for deeper editing: review the Studio handoff before adding custom code.
