The current giveaway on the main page (for Blacksad, at the moment) isn't working. The place where there'd usually be a button to claim the game just has three cycling dots which never load into anything else. Clicking on the giveaway itself just takes me to the store page and a "Go to giveaway" button that takes me right back to the non-functional banner on the main page. I've tried turning off all add-ons to my browser, which did nothing. Logging out DID make the claim button appear, but clicking on it just makes me log in and takes me back to the (now, once again) broken banner without claiming anything.

EDIT: Never mind, clearing my browser cache seems to have fixed the problem!

GOG Galaxy finaly added it dont know why suddenly worked.

WOW!!! This is the only post in fifteen years that actually seems to help with the broken giveaways, great work!

Has this been a problem for a while? I never had any issues until this one and I've claimed dozens of giveaway games. As for the clearing my browser cache "fixing" it, I seem to be mistaken. I somehow got it to work well enough to claim it, but when I look at the banner on the main page, it's still doing the three dots rather than saying it's already claimed. Oh well, at least if it happens again I've got a workaround. Thanks, everyone.

I had that issue as well. I had to clear browsing data and enable cookies for GOG to get it o work.

I've used this found by Palestine trick with internet adress:

"change the "www" in the URL to "embed", and press enter if this is not enough, press Ctrl+F5 to force reload the page"

It's works for a moment, just enough to grab GA.

Also I checked foad01 link: https://www.gog.com/giveaway/claim and it's work well.
