What we do not offer

Said plainly, so nobody builds against something that is not there.

• No JavaScript API to drive a game. You cannot start a level, set a difficulty, pause it or read its state from your page. What you get is a one-way postMessage signal when something happens (rewards) — and it is a signal, not evidence: anyone with a console can dispatch the same message. Anything that moves a ledger comes from our server to yours.
• No single sign-on. A visitor of yours is anonymous to the game unless you put your own opaque uid on the URL, and even then it is an id we store progress against, not an account. There is nothing to log in to.
• No white-label build. The games carry the studio's name.
• No downloadable copy. Embedding our origin is what lets us fix a bug for your visitors without you doing anything — and it is the only arrangement on offer.

And one that is a limit of the web, not a policy: a completion reported by a browser can always be forged. We answer that by replaying the move log where a game allows it — see tiers — not by pretending otherwise.

If your site genuinely needs one of these, write to us and say what for. Nothing above is a matter of principle; it is a matter of nobody having needed it yet.
