Skanda decided to leave SG :( so she put me in charge of the thread now. This is my first time hosting it, so bear with me if there are any mistakes.

[This year the themes/challenges are staying the same throughout the year and it’s up to you to pick one from the list every month.]

List of challenges:

1. Oldest wins - Take a look at the 10% of your earliest wins and pick one (or more) that you’re going to finish this month. If you’ve already finished all of them, pick the game(s) from the oldest 20% (and then 30%, 40%,…).
2. Most recent wins – Take a look at your 10% most recent wins and pick one (or more) that you’re going to finish this month. If you’ve already finished all of them, pick the game(s) from the newest 20% (and then 30%, 40%,…).
3. Short wins – Play and finish a game with an estimated time to beat of under 5 hours (according to How Long to Beat), but aim to beat at least 2 of them in one month.
4. Long wins – Play and finish a game with an estimated time to beat of over 15 hours (according to How Long to Beat).
5. Untouched wins – Play and finish a game that you have not played before – 0 achievements / 0 playtime.
6. Unfinished wins – Play and finish a game you’ve played (but not finished) before. You need to have between 25% and 80% of the How Long to Beat playtime in the game already.
7. Neglected wins – Play and finish a game that you’ve been meaning to play for a long time, but always ended up playing something else instead.
8. Wins idled for cards – Play and finish a game you’ve only idled for cards so far.
9. Wishlisted wins – Play and finish a game you won while it was still on your wishlist.
10. Number of days in a month – For games with achievements: get 1 achievement for every day of the month; by the end of the month you should have (at least) 28/30/31 new achievements in games you’ve won on Steamgifts. For games with no achievements: make 1 screenshot for every day of the month; by the end of the month you should have (at least) 28/30/31 new screenshots in games you’ve won on Steamgifts. In both cases you don’t have to actually finish the game(s) for the achievements/screenshots to count.
11. Month/season themed games - Play and finish a game you won in the same month (this year or in the previous years) OR a game that is somehow related to the current month (check out the October 2017 thread for more details and ideas).
12. Random wins - Submit yourself to chance and use www.random.org to roll a number of the page from “giveaways won”, then roll 1-50 for the specific game on that page. Reroll only if you’ve already beaten the game or if it’s an endless/multiplayer game that can’t be finished/doesn’t have an ending.

BONUS

13. Custom theme – Come up with your own monthly theme, tells us what the criteria are and which of your SG wins satisfy the requirements. Other people can join your custom monthly theme by replying to your comment.

Extra information (let’s not call it rules):

• You can pick the same challenge multiple times, but not more than 4 times in one year, or 2 times in one year if it’s the bonus (custom) theme.
• For a SG win to qualify for the challenge, you must have less than 40% of playtime (according to HLTB) in the game when starting the challenge. This does not apply to challenges 5, 6, 10, 13.
• If you’ve already finished 90+% of your SG wins, feel free to be more relaxed with the challenges/rules.
• If you’ve already finished all your SG wins, feel free to join the event with other games from your Steam library.

To participate:

Reply to this post to tell us which challenge you're going to do this month and which game(s) you're going to play.
Don't forget to include a link to your current progres in the game (if it has achievements). Once you finish the game, edit or reply to your post with a clear "finished". If the game doesn't have achievements, include a link to a screenshot you took while playing.

[OPTIONAL] “Challenge me”

Instead of (or in addition to) doing one of the 13 challenges listed above, you can ask for a challenge.
Reply to the application post saying that you want to receive a challenge and someone will give you a list of 3-5 SG wins to choose from.
If you want to challenge users make sure to pick SG wins that haven't been played yet (you can use the "Do You Even Play, Bro?" script) AND at least 3 games in the list need to be less than 20 hours long!
