Plan and test game mechanics

A mechanic needs an observable rule: an action, a change in state and feedback to the player. Before adding more systems, test whether the first action, win condition and restart work together. The existing guides below provide the starting workflow and debugging checks.

Prepare a game for publishing

Publishing starts with a game that can be tested, understood and maintained. Check the available creator controls, audience settings and safety requirements before a release. Use the publishing guide for the sequence, and the troubleshooting guide for an actual blocked step.

Roblox Build Missing on an Age-9+ Account

Build requires users to be age 9 or older. Build requires a completed account age check. A profile's stated age alone does not establish completion of that check or satisfaction of the remaining region and platform conditions.

Symptom

The account meets the stated age condition, but Build is missing or remains locked.

Immediate action

Check whether age-check completion is actually established, independently of the profile age value.

Diagnostic branches

Only the profile age is known.: Inspect the legitimate age-check requirement and completion state.
The tab explicitly asks for an age check.: Follow the official requirement rather than altering age information for access.
Completion is established but entry remains missing.: Use the remaining-condition triage for age-checked accounts.
The completed outcome is believed inaccurate.: Use official correction guidance, keeping accuracy separate from feature access.

Least-destructive change

Read the account's actual check state without changing truthful profile information or repeating a completed check unnecessarily.

Retest

Profile age and completed verification are recorded as separate evidence.
A fulfilled age condition does not become a blanket eligibility claim.
Already completed checks are carried forward rather than ignored.

Escalation

Provide official assistance the exact visible requirement if the account state remains contradictory. This guide neither verifies age nor promises access once an individual condition is met.

Working notes

Begin by separating the age value from the verification state. Knowing the account's birthday or displayed age is different from observing a completed age-check outcome. Do not assume that editing a profile field performs the verification workflow.

Read the actual entry state. A visible tab with a check requirement supplies a direct next action. An absent tab leaves more of the access question unresolved, so use the broader documented requirements instead of treating age as the only variable.

Keep the eligibility record honest. Mark age information, check completion, region scope and device wording independently as established or unresolved. Avoid a single eligible label based solely on the condition named in the search query.

If completion is already established, move to the age-checked-but-missing guide. Repeating the age explanation cannot resolve a remaining platform discrepancy or market question. The useful transition is from a known age value to a known check state, then to the still-open requirement.

Examples

Evidence distinction: profile age is known, but no check outcome has been observed. The next question concerns the legitimate age-check flow, not a presumed failure after verification.
Visible requirement: the entry appears and explicitly requests a check. Follow that prompt or current account guidance without changing the birthday to try to suppress it.
Completed-check branch: the account already shows a completed outcome. Carry that fact forward and investigate the remaining access conditions rather than asking the user to verify again by default.
