Once again, on occasion of a big sale, external sites have partnered with GOG to give away some juicy games! So far I have found:

PC Gamer: 500 games, 3 days left.

TechRaptor: 25 games, only 29 hours left! (It says "Part 1" but I can't find a Part 2 yet).

There's still time to enter and try your luck, everybody! ;)

Thanks for digging these up!

So both use Gleam, but while the TechRaptor one just gives one entry for visiting from there and the rest only if you follow stuff, the PC Gamer one gives 5 entries PER DAY for visiting GOG from there, so anyone signing up just now already lost 15 entries, since I see it was posted on Dec 23, but can still get the rest to the end if they don't forget. And there are additional entries for just visiting stuff too, though yet more for following and tweeting, all these being one time things though.

Thanks once again for these, ConsulCaesar!

Thanks. Made some dummy accounts and entered a few of them. Good luck to anyone doing it.

Thanks ConsulCaesar! we will try searching luck and if the game doesn´t like always could go to the Giveaway Community Thread.

Thanks for sharing :)

Thanks ConsulCaesar.
Does anyone have a direct link to the Gleam giveaways, btw?
(they don't load properly for me due to the anti-tracking plugins)

-- Same, but Twitter likes locking new accounts, asking for a phone number -_-'

I happen to have an old Twitter account I don't use anymore, so it was a chance to put it to good use. ;) But even just visiting GOG (or Facebook pages, you don't need to be registered) you can get some entries. Here you go:
PC Gamer: https://gleam.io/DHsQF/pc-gamer-and-gogcom-holiday-giveaway
TechRaptor: https://gleam.io/5yxui/techraptor-winter-gog-giveaway-part-1

Thanks.
Yeah, but I wanted the extra ones :P

Part 1 of the TechRaptor Giveaway is over, Part 2 is up! Another bunch of 25 games, it will be running for the next 7 days.

Direct Gleam link: https://gleam.io/3ObN9/techraptor-winter-gog-giveaway-part-2

They already did. Can't use the same account for the part 2 without entering a phone number :D. Like hell I am.

So I either have to make another one for part 2 or just ignore it.

Quick reminder: PC Gamer's giveaway ends today December 29, 2019 at 23:59 London.

TechRaptor's Part 2 will close on January 3, 2020 23:59 Eastern Time (US & Canada) .
