The Random To Do List Challenge - Season 2018 Trimester 2


The Great Annual Random To Do List Challenge was originally the brainchild of @FacialLaFleur. The idea was to use the TA “Add Random Achievement to the To Do List” functionality to add 100 randomly generated achievements to work on over the year, and the winner was the person who’d unlocked the most achievements after a year.

There were great prizes throughout the year and the grand prizes at the end of the year. There were always a lot of sign ups and good progress for the first month or two, but then things fell to a trickle once the list became more challenging. It was a lot of fun, but after the initial push, participants tended to lose interest and only a dedicated few could really get this list down. Only one person ever completed unlocking all of their achievements.

in later iterations of the contest, our own @zzUrbanSpaceman got involved and started adding advanced features such as exclusion lists, removing discontinued and unobtainable achievements (and in fact, this is where the terms “knobs and discos” originated from), and more.

@FacialLaFleur decided to stop running the contest, and so @Freamwhole and @zzUrbanSpaceman got together and decided to run their own variant of it.

With the help of the good folks over at True Achievements we were able to improve on almost all aspects of the contest and automate scanning, scoring, and many other cool things!

The Challenge

Every month, each player is given 25 semi-randomly selected achievements to work from. The achievements will be randomly selected from several bands of your available achievement pool. Your achievements are ordered by ratio, then your draw is selected from the following bands:

  • 14 achievements from the lowest 50% (up to the 50th percentile)
  • 7 achievements from the next 25% (50th-75th percentile)
  • 3 achievements from the next 15% (75th-90th percentile)
  • 1 achievement from the final, and top, 10% (90-100th percentile)

Points are scored based on the ratio of the achievements times 100, e.g. a 2.45 ratio achievement would be worth 245 points. Ratios are updated daily and so your scores may fluctuate based on changes to the achievement ratios on TrueAchievements.

Every month your progress is recorded, your list is wiped, and you’re given another 25 achievements.

This goes on for 4 months (one trimester), after which time the totals are tallied and the winner is crowned.

Good luck!

The Leaderboard and Statistic Tracking

We automatically select and record unlocks of the achievements in a public spreadsheet:

[Monthly Leaderboard] (

Additionally, global standings and historical lists are available in this spreadsheet:

Global Standings

As people unlock achievements, they will be automatically scanned and updates will be posted in the following thread:


  1. Achievements will selected from games listed in your TrueAchievements game collection based on the following criteria:

    • Games with a status of anything except “Done with”, and:
    • Games with an ownership status of “Owned” or “Games with Gold”
  2. Achievements will not be selected from DLC, title updates, or those flagged as discontinued, unobtainable, partially discontinued or unobtainable, or leaderboard required (TruSkill).

  3. Achievements will only be selected from Xbox 360 and Xbox One titles.

  4. You must maintain an achievement list of “locked” possible picks of at least 1,000 throughout the competition. This will ensure an appropriate pool of achievements to pull from as well as curb those unscrupulous hunters stacking their lists. You can see your current pool on the contest spreadsheet linked above.

  5. Each month starts on the 1st of the month at Midnight UTC (Universal Co-ordinated Time).

Contest Requirements

  1. Xbox LIVE Gamertag with at least 10,000 GamerScore
  2. Have a TrueAchievements account in good standing.

That’s all great but how do I join this crazy thing?

I’m so glad you asked! You can join at any time by simply posting in this thread with your gamertag or shoot zzUrbanSpaceman a message on TrueAchievements, Discord, or twitter @zzUrbanSpaceman.

It is highly recommended that you go over to and update your Game Collection:

You can edit the status of games by clicking on it’s boxart image when in Image View:

Or on the Edit button on the far right in List View:

Set the Ownership value as appropriate (usually “No longer have”) or set the Play status to “Done with” to avoid having achievements from that game selected.

You can also add games you have not started yet to your collection by going to the game page itself and selecting “Add to my Game Collection” from the Game drop-down menu:

I have an achievement in my list that I don’t want!

Don’t panic! We will reroll achievements in certain circumstances, including but not limited to:

  • Any Windows Phone of Windows 8 App achievement can be rerolled as these platforms are particularly flaky and can bug out or simply be wiped or lost. Additionally, many of these achievements are so ridiculously grindy that nobody in their right mind wants to do them. For the sanity of the organizers though, please remove these games from your collection if they are selected and you need them rerolled. Tarragon can get cranky if he has to reroll the same achievement multiple times.
  • You are new to the contest and didn’t understand how the TrueAchievements Game Collection worked.
  • An achievement has subsequently been flagged discontinued, unobtainable or PDU since it was selected.
  • An honest mistake was made when adding a game to your game collection, for example you added the wrong regional version of a particular title.
  • Other reasons at the discretion of the organizers.

UGH! Adding all these achievements to my TA todolist is painful, surely there’s a better way?

Indeed there is! Now, this is not compatible with all browsers, but is known to work in Firefox and Chrome. Firstly, go to your page on the public spreadsheet.

This is cell A27: it looks blank, but it’s actually a secret field which has some text you can use to populate your TA todo list.


  • Copy cell A27 from your sheet
  • Go to your homepage on TA
  • In the address bar, type javascript: then paste the text you copied earlier
  • Press enter
  • Wait a few seconds - it takes a little while to make a bunch of calls to TA, if you navigate away you may miss some todo list items
  • Go and look at your todo list
  • :dancer:

ENDED - The Random To Do List Challenge - Season 2018 Trimester 1

New lists are up, enjoy!


Let me guess… Over max draw value, will keep trying to find a list etc.


Correct, along with @SkepticalMario.


Seems to have found lists now.


I would like a list


Hi - I took the first few months off, but would like back in please. GT is MinPin. Thanks!

And at least for the cold I have, the secret is Mucinex + Ludens, with the occasional Excedrin. Feel better!


Too late for me to sign up? Or is this only for people that survived last round? Also, how much effort on your part is it to add someone that isn’t really trying? If the answer is virtually none, and I qualify for this round, put me in coach. Otherwise, see you next year. :slight_smile:


Same questions as LaFleur. Now that I’m out of GTASC I might be able to pop a few of these. :slight_smile:


Please add me back @CallSignIceMan


@FuFuCuddilyPoof, @FacialLaFleur, @jblacq, @CallSignIceMan you have lists now.

@MinPin Your pool size is 991, you’ll need to add some games before it will generate a list. This will happen automatically during the scans (every hour).

@FacialLaFleur it’s not a lot of effort, basically just adding some details to a spreadsheet and either letting the regular run do the work or kicking it off manually. :smile:


Weird, my collection on TA is showing me 1007 after I exclude all the Windows stuff. I’ll make a couple changes. Sorry!


We have some extra exclusions in the calculation - no leaderboard achievements, for example.


Thanks. I realized I messed up the dlc setting. Have the list now, really appreciate it!


Thanks! [toast]


How exactly does the exclusion of the leaderboard achievements works? I have this on my list: and it has the “Online Skill” flag. Not really complaining about that, just curious.



Well, they are supposed to be excluded:

The achievement flags should not be any of: “discontinued”, “unobtainable”, “partially discontinued/unobtainable”, or “leaderboard required”.

So, that would probably be a bug.

Happy to re-roll any leaderboard achievements.


In that case I would like a re-roll for that one. Hopefully I will get something that I will complete. Thanks. :beers:


Cleared it, it’ll reroll during the next scan.


I was bumped as last month was too busy for me to take part, any chance I can get back in?
