This game stores challenge choices and move history in localStorage on this website. This data stays in this browser. It is not sent to a game account or our server. Each game subdomain has separate storage.
No account required
The game does not ask for a name, email address or payment details. The game code does not load advertising or analytics scripts. The hosting provider can process standard request information, such as IP address and requested page, to deliver the website.

Restart replaces the selected challenge after confirmation. To remove all saved progress, clear this site’s data in your browser settings. Private browsing, blocked storage or cleared site data can prevent progress from saving.
When storage fails
An on-screen message explains the failure and offers a retry. Unreadable records are kept until you explicitly choose to replace them. You can keep playing temporarily in the current tab.
