Terms

Satoshi.game · last updated 20 July 2026 · this is a beta, and material changes will be announced in-game.

Satoshi.game is a free browser game made by one person. These terms are deliberately short and in plain language. By playing, you agree to them.

No real cryptocurrency

This is a game about Bitcoin's mechanics, not a cryptocurrency product. The bitcoin, cash, Genesis Points and every other currency in the game are fictional numbers in your save file. Nothing is on a blockchain. There is nothing to buy, nothing to earn, no wallet to connect, and no way to convert anything in the game into money or any other asset of real-world value. Nothing here is investment advice or a financial product of any kind.

Satoshi.game is not affiliated with, endorsed by, or connected to Bitcoin, any cryptocurrency project, or any company. It is a work of fiction that borrows real history for flavour.

It costs nothing

The game is free. There are no purchases, no subscriptions, no ads, and no premium currency. If that ever changes it will be announced well in advance, and it will not retroactively take away anything you already have.

Your account and your saves

Accounts are anonymous by default and created automatically. You are responsible for keeping access to yours — a guest account has no password to recover, so linking an email in Settings is the only way back in if you lose your browser storage.

This is a beta and saves are migrated best-effort. The game has carried saves forward across every format change so far, and the intent is to keep doing that. If a change ever makes a migration impossible it will be announced on Discord before it ships. You can export a backup of your save from Settings at any time, and doing so occasionally is a good idea.

No guarantee is made that any particular save, account, or amount of progress will survive. Please do not treat a save file as something valuable.

Fair use

Please don't:

attack, overload, or attempt to break into the game's servers, or test their security without asking first
automate mass account creation, or create accounts to abuse limits
use the game to store or distribute anything illegal, or to harass anyone

Modifying your own single-player save is not something we will chase you for — it only affects your own game. The save-import feature in Settings exists so you can restore a backup. Saves that cannot be verified by the server are marked as such, and if competitive features such as leaderboards are ever added, they will use that mark.

Access may be suspended for anything in the list above, or for behaviour that puts the service or other players at risk.

The game is provided as-is

Satoshi.game is offered without warranty of any kind. It may contain bugs, may lose data, and may be unavailable, changed, or discontinued at any time without notice. To the fullest extent the law allows, the author is not liable for any loss arising from your use of it — including lost progress.

Nothing in these terms limits any right you have under consumer law that cannot be waived.

Source code

The source is public under the PolyForm Noncommercial 1.0.0 license: you may read, modify and share it for noncommercial purposes. Commercial use requires a separate license. The license covers the code — it is not permission to use the name Satoshi.game or to run a public copy presented as the original.

Changes

These terms may change as the game does. Material changes will be announced in-game and the date at the top of this page will be updated. Continuing to play after a change means you accept it.

Privacy

What the game stores and why is covered separately in the privacy notice.
