A small site.
A small data footprint.

SixFiveSix does not add analytics, advertising trackers, cookies, or browser storage. You do not need an account to play.

Your puzzle stays in the tab.

Your moves are held in the page’s memory. They are not sent to a server and they disappear when you reload or close the page. Fonts, scripts and artwork are served with the site.

Hosting and ordinary web requests

Vercel hosts this site. Loading a page sends ordinary connection and request information, such as your IP address, browser information, requested address and time, so the hosting service can deliver the site, protect it and diagnose problems. These hosting records are separate from your puzzle moves. See Vercel’s privacy notice for information about its practices.
