A straight answer to the fair questions a grown-up asks when a game mentions Bitcoin. No spin.
The short version: the game works completely without any money involved. Bitcoin is an optional layer a parent switches on — never the default, never required to play.
No. Reward comes from work, not chance. Every pickaxe swing runs a real calculation (a hash); doing more of it, with better tools, earns more. It's the opposite of a slot machine — there's no stake to lose, no bet, no "spin." It's designed as a way to learn how proof-of-work actually works, by doing it.
Only if you choose it. There's no money in the game by default. Payouts exist only on Bitcoin-enabled servers and only when you, the guardian, allow it — with controls per child and per server. Many families will play with it switched off entirely, and the game loses nothing.
Nobody but you. The wallet is non-custodial — derived from your child's own key, on your device. We never touch, hold, or move funds. That's a deliberate, hard line: the platform is not a money service.
There are no passwords and no email harvesting. Players sign in with Signet — a portable identity you own. As a parent you hold the account and control nested child accounts under it. Nothing to leak, nothing we can sell.
By default, no. Identities are private unless someone deliberately chooses to go public — there's no accidental public profile, and a child shows up as a cryptographic handle, never their real name. Going public is always an explicit, opt-in choice.
There isn't a hidden one. No ads, no loot boxes, no paywall. It's open source, and you can even run the whole thing yourself on your own machine. We're backed by people who choose to support the project, not by selling your child's attention.
It's open source — you (or someone you trust) can read exactly how it works. And if you've got a question we haven't answered here, we genuinely want to hear it.
