The game

From a dusty garage to a warehouse full of hardware

Start with one miner and a power strip. Every upgrade, every new shelf and every rare find brings your farm closer to the hall.

Build your mining farm

Put miners on the shelves, keep power and cooling in check and watch the hashrate climb. Your farm keeps mining while you are away.

Unbox rare miners

Every miner comes in a revision from D to S. The rare ones hash harder and run cooler, and an S is worth the wait.

Upgrade to bigger miners

Climb from a humble open frame to liquid-cooled giants. Tune up, swap models and chase the next tier.

New locations

Outgrow the garage. Move into a basement, then a warehouse, with more shelves, more power and more heat to handle.

  • Basement

Quick answers

Short answers to the things people ask first. More on the support page.

Is the BTC in the game real?

No. Mining Fever is a simulation game. All in-game currencies, including BTC and cash, are virtual: they have no real-world value and cannot be withdrawn or exchanged.

The game follows the public Bitcoin price only to make its simulation feel alive.

Is it free?

Yes. The game is free and has no in-app purchases. It is supported by ads, and rewarded videos are always optional: you choose to watch one for a bonus.

Do I need an account? Where is my progress saved?

There are no accounts and no sign-in. Your progress is saved on your phone. If you uninstall the game or clear its data, the progress is gone. Your phone’s own backup may restore it, depending on your device settings.

Which languages does it speak?

The game follows the language of your phone: English, Russian, Spanish, Portuguese, German, French, Turkish, Japanese and Arabic.

Is it for children?

Mining Fever is not intended for children. Read the Privacy Policy for details.
