It's an open-source block sandbox where your child owns what they build — not a Bitcoin game with a child bolted on. Here are the straight answers to the questions that matter. No spin.
The short version: it's free — no ads, no loot boxes, no paywall, and it works completely without any money involved. Bitcoin is an optional layer you switch on — never the default, never required to play.
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.
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.
No. Anything tied to the mining is based on work, not chance. Every pickaxe swing runs a real calculation (a hash); it's the opposite of a slot machine — there's no stake to lose, no bet, no "spin." Today it's there to learn how proof-of-work actually works, by doing it (and to keep mining honest) — not to win or lose anything.
Not today. There's no money in the game — any real-money payout is deferred and switched off. If it ever comes, it will only be on Bitcoin-enabled servers and only when you, the guardian, switch it on — with controls per child and per server. Plenty of families will play with it 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.
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.
