Tool rules

Show the data date it was built on.
Display NEEDS_VERIFY when data is missing instead of inventing a value.
Handle empty, invalid and unknown input with a clear message.
Work on mobile — most players use these while the game is open.
Link to the guide or data page behind every result.

Formulas must be reproducible

We only publish a calculation if a player could redo it by hand. That is why there is no damage calculator yet — the official formulas are not available to us.

Deliberate exclusions

What we will not build

Scripts, cheats or auto-farming. Excluded entirely, and the topic is not covered anywhere on this site.
Robux, account trading or generator tools. These exist only to take accounts, so they are not here.
Drop-rate calculators until reliable official probabilities exist.
Automatic code checkers that hammer third-party endpoints. Codes are verified by hand instead.

Frequently asked questions

Do these tools require an account?

No. Nothing on this site requires a login. The checklist saves progress in your own browser only.

Is my progress saved?

The survival checklist saves to your browser’s local storage. Clearing site data resets it, and we never see or store your progress on a server.

Why are there no damage or drop-rate calculators?

Because we do not have reliable official formulas or probabilities. Publishing a calculator built on guessed numbers would be worse than publishing nothing.

Sources and verification status

Tools are built only from facts that appear elsewhere on this site with a source and a confidence level. Where data is missing, the tool says so.
