Hello Keith! I'm loving the new attention to achievements. I'll likely have some more thoughts & feedback as I keep trying to earn more (haven't spent much time on Tiles or HA contests) but figured it might be useful to share some things I've noticed.

edit: sorry, the tiered lists don't seem to be working, I'll try to play with formatting to make this more readable]

Actual achievements

• Prismatic achievement is unclear or is unachievable --> What is this achievement looking for? Based on the current wording ("All six colors maxed out? You've mastered the left side."), it suggests playing a game where you have 36 points plus the bonus on the left side (or functionally, getting "unified matter" 6x in one game, once for each color). I think that's pretty much impossible to get, especially given how rare it is to get unified matter for any color, so I'm hoping I'm misunderstanding it.
• Crack the safe 30 days in a row seems unachievable --> Attempt to crack the safe 30 days in a row seems very achievable, but actually cracking it 30 days in a row seems wildly difficult (but it's possible I'm just bad at safe cracking :P)
• Shiny minion popping might be bugged, or description needs clarification --> "Trapped Minions: pop this many rare shiny (golden) bubbles." --> A friend shared a screenshot of popping a shiny minion (yesterday, so not a cache issue), but her shiny minion achievement count didn't go up. The minion went to someone else, which may be relevant. For another shiny bubble, she got the minion but not the final pop, and her count also didn't go up. Do you have to pop the bubble and get the minion? If so, would love to make that clearer in the description. If you just need to get the minion or just pop the bubble, we think there's a bug

Achievements page

• Make All/Earned/In Progress/Retired filter choices persist --> Right now, if I go to the achievement page and click "in progress" (which I do 95% of the time I am checking my achievements), each time I click into a sub section or use the search feature, I have to select "in progress" again
• More readily differentiate between fully completed achievements and incomplete achievements --> Laurey suggested this here
• Show secret/hidden achievements --> Some achievements seem to be "hidden" i.e. not findable except by search. E.g. the safe achievements should be in the games section
• Add some way of showing how rare achievements are, ideally % of users who have the achievement --> I'm sure you have visibility into this, but it would be very cool for users to see! --> This would also help users understand how feasible achievements are. E.g. Prismatic
• Improve searchability or organization --> We have a trapped minions section - could that be a subsection under games? and maybe could we get more subsections? or just for ease of searchability, could grouped achievements use the syntax that trapped minions does? --> "Angrybeard's Expedition" is an example of this syntax, but the game is called Leviathan Harpooning. Could we either change the game name to "Angrybeard's Expedition" or update the descriptions to have the prefix "Leviathan Harpooning" instead of "Angrybeard's Expedition" to reduce confusion?

Other

• Achievement counts are incorrect --> See topic ">here. There are two separate issues: one where achievement counts are far higher than they should be (true for HST, hovering over a username, & on user profiles), and one where achievement counts are far lower than they should be (showing on forums below people's HAs)
• Achievement widget sections ("Your Achievement Progress") under their relevant pages don't seem to be updating --> E.g. on the trapped minions page, my progress seems to be stalled: it shows I have fed minions 1,060/1000 times and have none of the other achievements, whereas I have actually fed over 14k and have completed multiple tiers of most of the others.

Let me know if I can provide more detail or screenshots! I figured screenshots would be overwhelming/overkill given how long this list is, but happy to provide anything that might be helpful.

Ooh glad to see this thread! My feedback is about the look of the achievements page:

1. earned achievements are red, unearned ones are neutral. seems like at least earned ones should not be red; i keep thinking that means i DONT have them
2. on this note- for achievements that require multiple items, im having a hard time differentiating now between what I do and don't have. when it loads the required items, ALL of them are red, even the ones I have. looks like there is a slight color contrast but its super subtle. so just something more high contrast here
3. this is so stupid but to me light blue text means hyperlink. on earned achievements now, the number for the tier is blue so i keep thinking its a link or a clickable button and it isnt and its driving me insane bc i feel so dumb that I keep doing it LMAO (probably bc the things that are clickable are also blue). (you can see below that the "1" is not clickable, but the 2 dropdowns are. could also just be because Im used to the star next to these types of achievements being the thing that pops up the reward.

ty for taking a look! i forgot to upload a pic to illustrate point 2 so here you go~

I love the links, thank you for adding those to the new ones! I am legitimately happy to help with backfilling if you want - if you can get me a spreadsheet or list of achievements that need links, I can add in a column with links. Or even just tell me to go do that and I will go through the achievements page and come up with a achievement name/id/link spreadsheet or whatever format would be easiest for you to ingest/use. If you're open to that, feel free to message me on discord or sMail me here or whatever's easiest, it sounds like a mindless fun project to me xD. (and I bet I can find a few more folks willing to help so we could spread the work even more if you're okay with that)
