How to use Offline Manager
What gets stored
The site's own shell — pages, styles, scripts and icons — is kept on your device after the first visit, so a game you have opened once still opens with no network. Game files are stored when you first open them rather than all at once, so a first visit does not pull down a hundred games you may never touch.
The check reports the real list
This page asks the offline worker what it actually has and shows the count and the file names. When it cannot get an answer it says so, rather than showing a reassuring tick. A tick that was guessed at is worse than a plain 'cannot tell' — you would rely on it, go offline, and find the page will not open.
Clearing is safe and reversible
You can clear the stored copy at any time. The button right beside it stores everything again, because clearing something with no way back would be a trap rather than a choice.
Newer versions replace older ones
When the site is updated, the previous offline copy is discarded rather than kept alongside. Keeping both would mean loading a file the site no longer expects, which is how offline modes end up showing a broken page.
Only this site is stored
Nothing from anywhere else is kept, and no part of your progress is involved — the offline copy is the site's files, not your scores. Clearing it does not touch what you have played.
Offline Manager — Frequently Asked Questions
Why does it say it cannot tell me what is stored?
Most likely because this is the first load, before the offline worker has taken over — reload once and it will report properly. It also cannot work if you are opening the files straight from disk rather than from a web address.
Does clearing this delete my scores?
No. This is the site's own files. Your progress is stored separately and is untouched. To clear progress, use the clear progress page.
Do I have to do anything for offline play to work?
No. It happens as you use the site. This page is here so you can verify it rather than take it on trust.
Can I play offline right after the very first visit?
The page you are on is stored on that first visit, so yes for that page. Other games are stored when you first open them.
Does it need installing or an account?
No. It is a web feature of the site itself, with no app and no sign-in.
