After you joined, don't forget to sync your account to make the giveaways from this group fully visible (Account → Sync Account → Force Sync).

You can find the first group giveaway, visit this page to choose the next and last group giveaway, pick one or more games in the list by adding a comment.

This first giveaway ends on 10 September 19:00 CEST.

Two solvers didn't follow my instructions on how to join the group («Don't forget to post a comment if you are interested to receive an invite for the group»), actually they have 0 comments in their SteamGifts profile. Maybe they don't even know there is a group giveaway too. I'll replace them inviting two of the solvers of Award's Alchemia puzzle, Robbed and Rosebuster, who entered the giveaway for this game without winning (the remaining two entries are the winner and an user who already own this game now). Dura lex, sed lex.
