UPDATE: Nothing to see here, move along.
Note to self: remember to check stickies ;)


I couldn't find the relative thread or official news post, if there ever was one... Did I miss it?
Anyway, I found this on Reddit.

"1. Listen to 7 music fragments
2. Guess all 7 great games
3. Send the names of those games to contest@gog.com
4. ???
5. Profit

The video above contains 7 music fragments coming from 7 great classic games. Can you name those games? If you think you can, there's a free GOG.com game in it for you! Just send the correct game titles (in the order that they're presented in the video!) to: contest@gog.com (enter "Music contest" as the topic, please)

The first ten people who email us with all the correct answers put in correct order will receive a bonus code. Another batch of 10 codes will be distributed among the users who sent their correct answers later. The awarded codes will allow you to redeem any GOG.com game with a regular price up to $9.99.

This contest lasts until Friday, September 14, 9:59 AM GMT, so put your headphones on, sit back and just go with the flow of the music, while your memories begin to kick in!"

EDIT: Sorry for the very official-news-like topic.

The sticky can indeed be hard to miss.

Ha!
Thanks guys, completely missed the sticky ;)
