Privacy & cookies

Essential cookies. nbk_gid is a random guest identifier that lets favorites, recently played games and saved progress work without an account. nbk_session keeps you signed in. nbk_consent remembers your analytics choice.

Analytics (opt-in). Only if you choose “Allow analytics” we record anonymous gameplay events (e.g. game started, game over, load errors) linked to the random guest/user id — never your email. You can change your choice by clearing the nbk_consent cookie.

Accounts. We store your email, display name and a salted scrypt hash of your password (never the password itself). Display names appear on public leaderboards.

Advertising. No third-party advertising or tracking is active on this site.

Games run in sandboxed frames that cannot read your cookies or account.
