Cookies the site needs

• session: signs you in, or, if you play the bot as a guest, ties your games to this browser. Deleted when you sign out; a guest session lasts 30 days.
• csrf: a token that proves a form or a move was sent from this site and not by another page in your browser.
• consent: remembers what you chose on the cookie sheet, and which version of this page you chose it for. Lasts 12 months. Storing your choice needs no consent of its own.

Advertising cookies

If you choose Accept, the ad network's script loads and may set cookies of its own to measure and personalise advertising, under its own consent message. If you choose Reject, no ad script loads and no such cookie is set. The site works identically either way; ads are never a condition of playing.

Cookie settings

Your answer today has not been given. Change it here; the choice lasts twelve months. Changing this page in a way that changes what is collected bumps the policy version, and the sheet asks again.

What is not here

No analytics cookies, no beacons, no third-party scripts other than the ad network after consent. Counts of games and timings of requests go to a monitoring system on our own server and never leave it.
