Disclaimer

Last updated: September 2026. Please read this page carefully before using our calculators.

Educational information only

All content on PocketArcade — calculators, articles, tables, and examples — is published for general educational purposes. It is not game-safety advice and is not a substitute for a qualified professional. We are not each game's official license file (open-source titles) and your device's parental settingss, and no client or advisory relationship is created by your use of this Site.

Games in the "Classics Library" are unmodified copies of legendary open-source games, hosted with their complete source code and license files intact — see our credits page for each project and license.

Progress and high scores are stored only in your own browser's local storage. Some games use sound; check your volume before starting. Nothing is ever uploaded from your device.

Accuracy of calculations

We implement well-known, publicly documented formulas (see the methodology section on each calculator page and the games' own documentation and open-source licenses as applicable). Even correctly implemented formulas produce estimates that depend on your inputs and assumptions. Real-world outcomes vary. Do not rely on a single web tool for a consequential decision.

Advertising disclosure

PocketArcade is funded by display advertising served through Google AdSense. Advertisers have no influence over our content, formulas, or editorial choices, and placement of an ad is not an endorsement.

Errors and corrections

If you spot an error, please email contact@nftycalcs.com with the inputs you used. Verified corrections are published promptly.
