Free GOG Games

You can give them away here in the forums for free. There are a couple of threads you can use already.

I accept any game 👍

You can absolutely ask people here in the discussions if they want keys for games on GOG for free - no problems.
List the games and/or make some hoops for people to jump through, like puzzles, jigidi's, or just give 'em straight up to anyone that asks - it's all your choice.
You can't make GA's for them - that is Steam keys only as the site is not built to check you redeem keys properly on other sites/launchers. But you can for sure make a discussion thread (or even edit this one) and give such keys away. If you look through discussions you'll likely find more than one such thread from before if you want to see how/what others have done in similar situations.

Just don't post the keys openly here, there are to many bots crawling the site looking for codes - they will likely be ninja'd before anyone gets to have some fun with them.

Have fun!

Hi! Thank you very much for the opportunity. I might be interested in some games that I didn't redeemed in time, like Thronebreaker and Stray Gods, do you have them? If yes, can I have the keys? Can you also make a list please?Thank you

Thanks for the answer, my idea was to post a list with all of them, for free or if I find any way to do puzzles
I will do it later
