Frequently asked questions

An idle / incremental tycoon and wealth-management game. You start with $100 and a single corner store and build a global empire — shops, factories, banks, an airline, a space programme, a live stock & crypto market and real estate — then spend your fortune on a full personal-life layer (homes, cars, yachts, jewellery, education, family) that loops back to boost your income.

Yes. Quadrillionaire is free to download and fully playable without spending. It includes optional rewarded video ads and a single one-time "ad-free" purchase that makes the ad-gated shortcuts instant.

iPhone via the App Store. iPad, Mac, Android & web are coming soon.

You can play offline; the game credits idle progress when you return (up to a 72-hour window). An internet connection is needed for cloud save sync, the live market feed and ads.

Yes — sign in with Apple, Google, Microsoft or email and your empire syncs to the cloud. You can also play as a guest, in which case your save stays on that device.

Your save syncs; if two devices diverge, the game shows a "which save wins?" screen so you choose.

Make sure you're signed in with the same account; your cloud save restores on launch. If you were a guest (not signed in), local-only saves don't transfer between installs.

Income accrues every second whether you're playing or away, credited when you return (bounded to 72 hours), using a tamper-resistant clock.

No. Ads are entirely optional and only ever skip wait timers or grant small conveniences. The patient player can reach everything for free.

It's a one-time purchase that makes every "watch ad" shortcut instant — it buys time, not power.

Purchases are handled by Apple or Google; refunds follow their policies and your local consumer law.

No. The casino/underground content is a simulated, in-game-only feature with no real-money wagering and no real-world payout. In-game cash and items have no real-world value.

Because it includes frequent simulated gambling — an in-game casino plus risky Underground and Government operations played entirely with virtual currency. There is no real-money wagering and no real-world payout, but Apple rates frequent simulated gambling at 18+, so the game is intended for adults.

Account info if you sign in, your game save, plus analytics, crash reports and (for ads) an advertising identifier with your permission. See the Privacy Policy.
