Privacy

You can play every game here without an account. We do not ask for your email or other account details, and we do not set cookies ourselves; the advertising described below does.

Game progress. Your saved progress stays in this browser. Clearing browser data removes it, and saves do not follow you to another device.

Plays and records. Pressing Play adds to the game’s daily play count, and while the game is on screen this page reports how many seconds it was played, counted per game and tied to no browser or address. A ranked submission sends your result and chosen name, and may include your moves or a replay so the site can check it. Accepted results can appear in the game’s Top 10, and some rankings offer replays to watch.

Ratings. After a minute of play, you may give a game one to five stars. A random identifier kept in your browser makes this one rating per game; rating again changes that rating rather than adding another. To discourage duplicate ratings, your address is turned into a salted hash that changes every week. We never store the address itself, and the identifier is not an account or used to follow you between games.

Your name. Choose a name with the header button, or leave it blank to appear as Anonymous. It is saved in your browser, sent to the site for validation and stored with ranked results. There is no account, password or email, and names are not exclusive. Use a name you are happy to show publicly. You can change or clear it; earlier results keep their original name. To limit abuse, your address is converted to a short hash that changes weekly, kept for a few minutes and never stored as the address itself.

Tutorial videos. Some game pages have a video showing how to play. Until you press it, it is only a picture served from this site. Pressing it plays the video, either from this site or, for videos published on our YouTube channel, through YouTube's player from youtube-nocookie.com; from then on Google's privacy policy applies to that player.

Reporting a problem. The Report a problem and Suggest an idea buttons open our public issue tracker on GitHub in a new tab, with the game already filled in. Nothing is sent until you submit there, what you write is public, and GitHub's own terms and privacy statement apply to it.

Hosting. The site is served by Cloudflare, which processes technical request data such as IP addresses to deliver and protect it; see Cloudflare's privacy policy. We set no cookies of our own and use no third-party analytics. Nothing on this site profiles you or follows you between visits. To know how busy the site is we read the totals Cloudflare has already counted — how many requests and how many distinct addresses per day, and which pages they asked for. We keep those totals, never a log of visits, and they say nothing about who you are or what you did.

Advertising. The pages around a game and the game wikis may show ads from Google AdSense. The games themselves carry no advertising. Google and its partners may use cookies and similar identifiers to show and measure ads, and personalised ads only with your consent where the law requires it; visitors in the EEA, the UK and Switzerland are asked first. Learn how Google uses information from sites that use its services, and manage personalised ads at Google Ad Settings. You can also opt out of personalised advertising from many ad companies at aboutads.info or, in Europe, Your Online Choices.
