Show HN: Logiquiz - Daily Self-Referential Puzzles
Hey HN, About twenty years ago, while I was in college, I first
stumbled upon James Propp's Self-Referential Aptitude Test [1] and
absolutely loved it. Ever since then, I've had this idea of turning
that concept into a daily game, and I've finally built it:
https://www.logiquiz.com/ The game interface checks each question
against the answers you've given, so it doesn't spoil anything by
giving away the answers. There are five different tests each day,
from very easy to very hard. I'd love to hear what you think!

| These are really fun, thanks for posting this. Only weirdness

| Puzzles [1], where each clue is validated against whatever is
| on the grid right now, not against the expected answer.

|
| If Q1 is "the answer to Q2" and I mark A:A, Q1 should be red
| if A is crossed off for Q2, yellow if A is still an option
| for Q2, and green if A is the chosen option for Q2.

| "what is the only answer with ${q}?" seems like a bug.
| slig wrote:
| Indeed, thanks for spotting. Deploying the fix right now.
|
| edit: deployed, sorry about that!

| It took me a second to realize "has the answer E" meant "as the
| answer" not "as an option," but I think that's a glitch in my
| brain, not the puzzle.
|
| I did accidentally pull down too hard on my screen when I was
| trying to scroll up, which accidentally refreshed and deleted all
| my answers on all difficulties, not even just the one I was
| working on/hadn't solved yet, so that's less than ideal. I almost
| had level 4 done, but no way I wanted to go back and redo it all!
|
| I'd also love an "answer lock" button, and/or floating undo/redo
| buttons, because sometimes to take the next step, I need to put
| in an answer and game out how the rest of the puzzle comes
| together with that answer, and it would help to be able to undo
| back to that point, not just try to count my steps and keep
| scrolling down to the undo button for more of them. I'm not
| likely to get out a piece of paper or pop open a notepad app to
| game it out that way.

| Argher wrote:
| Maybe "Which question is solved by E?" or "How many
| questions are solved by E?" - another way would be "Which
| question has E as its correct answer? // Which question is
| answered by E?" or "How many questions are answered by E?"
|
| I personally like the solved wording.
|
| Also another vote for clearer colors about possibility
| state - for example, the cells are marked green if that
| specific answer is internally consistent, but it can still
| be an incorrect solution overall, which means you did not
| get the correct answer whatsoever.
|
| I think people (myself included) have been trained to think
| green = good, meaning that answer is correct and shouldn't
| be moved, you found that one, now work on the others - so
| an intermediary color as mentioned, like yellow, meaning
| 'yep that's plausible but not necessarily _right_ ' would
| be a good fit there.
| smeej wrote:
| I would go with, "Which question has E as _its_ answer? "
| or " _the_ answer " instead of " _an_ answer " would fix
| it for me.
|
| Similarly, "How many questions have E for _the_ answer? "
| smeej wrote:
| I think it also threw me because we have a trick question
| in English, "How many months have 28 days?"
|
| All the months have 28 days, but people usually answer 1,
| so for those of us who are used to approaching questions,
| especially logic questions, as literally a as possible, all
| the questions have the answer E. It's just not the _right_
| answer. "How many questions have E _as_ the answer? "
| would clear that up for me.

| Sorry about the pull to refresh glitch! Completely forgot to

|
| Thanks for the other feedback!

| Not really surprising, but was still nice to see
