I love this!

Haven't yet really tried the full level but really liked the tutorial, and the quality of the build

update - wow the actual level is better ;)

nottheg•3w ago
Also OMG I've just read your bio - I saw and wondered what someone more from the software side (rather than philsophy) would say: https://open.substack.com/pub/mcauldronism/p/the-maintenance...
eru•3w ago
Seems like the same idea as treating your LLM as a compiler.

When you write code in Rust and user your compiler to produce an x86 binary, you don't maintain the binary. If you want to make a change, you toss away the old binary, change your Rust code, and recompile.

codingdave•3w ago
That concept has been floating around a few places recently. It is wishful thinking. Your userbase won't accept constant small changes in UX, functionality, or the same bugs returning every time you update the production code. And that is what you will get if you run a non-deterministic compiler that hallucinates.

lovegrenoble•3w ago
I love games where the rules can be understood in seconds
romanhn•3w ago
That was fun until I got to the point where no progress could be made and I had to undo a whole bunch of times to get to a workable configuration. Perhaps add a notification of some kind that I've gotten myself in that situation, rather than letting me kill a bunch of time solving an unsolvable puzzle. Still, very enjoyable!
trueno•3w ago
lmao same. actually a really cool fun/concept it's definitely wordle popularity caliber, but once i got to the last 3 words and ended up in this scenario and the hint button said that i was like -_- owned.

not sure what the right game experience would be for that. a notif that says "You can still solve more words but you'll never solve them all!" doesn't quite work here, because it's sort of saying "there's only one _right_ way to win, but good luck figuring out the right order". Still, it would be better than me finding that out at the very end.

it would probably be pretty important to design levels so that the unwinnable states can't happen early in the game, but it's getting a little abstract to think about at this point. sort of brings me back to that unblock it game from the old ipod touch days.

bryanrasmussen•3w ago
maybe a percentage chance of solving puzzle tracker that updates a bit randomly slow so you don't necessarily know right away that you made a mistake, although it would have to be a bit weird, for example when you start you are not at 100% of solving puzzle.
hahahahhaah•3w ago
There could be a 2 player game where whoever gets stuck (or empty board) loses.
BoppreH•3w ago
Same here. On yesterday's puzzle I got into an unwinnable state on my very first move, using the topmost word (spoiler: I made "hut" instead of "out").
aszlig•3w ago
There is a "Auto-hints" setting that should highlight the undo button in red once you're in an unwinnable state: https://uncrossy.com/settings.html
paulnpace•3w ago
That option shows up in the Puzzle Solved! dialog box.

#Uncrossy Jan 8 in 18 moves, in 2:23, no hints, no resets, no undos, auto-hints on ⬅⬅⬅⬆⬅⬅⬆⬇⬆⬇⬅⬇⬆⬇⬅⬇ https://uncrossy.com

emzo•3w ago
Yes it's annoying, but that's part of the puzzle right?
jrboyens•3w ago
Very nice. Easy to accidentally cheat, however. Shift a word to an invalid position, but right click instead of letting the mouse up event fire. Then shift the word back to the original position: win!
ocdtrekkie•3w ago
This is really, really cool. I think telling me how many moves I have to go back in the hint was absolutely a must-do, and shouldn't cost two hints... Second-guessing every single move I made would be insane, but knowing I had to go back seven, and pick something different than the last thing I restored, that worked fine.

It's easy to assume making a word disappear is always the right choice, but you forget it changes the word it leaves behind as well. Very clever.

It does have the same quirk Wordle had that bugged me: Treating browser storage as useful in our multidevice world.

degamad•3w ago
> It's easy to assume making a word disappear is always the right choice, but you forget it changes the word it leaves behind as well. Very clever.

It's also easy to make the opposite assumption, that the goal is to change the other word. I initially felt weird about changing from a letter at position 3 to the same letter at position 1, but eventually realised that the goal is just to slide the word around, not necessarily to make a new word.

mb7733•3w ago
Really fun. The undo/redo functionality is much appreciated.
incr_me•3w ago
Fun! On first thought, I'd prefer knowing when I'm in an unwinnable state instead of having to keep clicking the hint button.

Also, the site worked for me in Chrome but doesn't work in Firefox (145.0.2). Do `window.cookieManager = ...` (or even `var cookieManager = ...`) instead of `const cookieManager = ...`. This goes for all variables in the global lexical scope you intend to share across source files.

eru•3w ago
Worked for me in Firefox 146.0.1.
ninalanyon•3w ago
Ditto.
Grom_PE•3w ago
It doesn't work when uBlock Origin blocks uncrossy.com/js/cookieManager.js?v=7
incr_me•3w ago
Oh, that's it. My bad!
truekonrads•3w ago
Cute. Lots of "-ed" matching tho
Snacklive•3w ago
Fantastic work, very fun ! I actually only ran into the dead end scenario right until the last few words so not a frustrating first experience. But reading other comments maybe a setting to prevent the player to take a route that ends up unsolvable would be great. Kinda like the "Normal" and "Expert" Modes in worldle
mlavgn•3w ago
I was hoping this was like the game Crossy Road, but your goal was to throw yourself into traffic
mastermedo•3w ago
Love the idea. It's fun to play.

I didn't like that it's possible to leave the underlying word unchanged by dragging the word containing a letter twice to the second occurence.

Tiberium•3w ago
Was a bit disappointed when I almost "solved" it but couldn't solve the last 2 words, finally clicked the hint and it told me to undo 12 times.. would have preferred if there was a warning earlier.
oliwary•3w ago
Nicely done! This is an excellent experience, both visually and gameplay wise.

The only thing that felt a bit weird was being able to change the word to the same word, if the slid word had the same letter twice.

deviation•3w ago
I love it. My bets are on that this idea will be stolen and turned into some micro-transaction plagued app on store before the end of the week.
greener_grass•3w ago
Tutorial was pretty confusing to me. I formed "HIM" and it rejected it, no explanation why.
sp8•3w ago
Oh that was way more fun than I expected! I feel I shall be playing this regularly!
spuz•3w ago
This was really fun. I actually went back to the beginning of the archive to find more puzzles to solve. I think it would be nice if when you have solved one of the historical puzzles it would give you a button to click onto the next day's puzzle.

I actually never came across the situation where my grid was unsolvable. As I was playing I was wondering what kind of algorithm you used to come up with grids that have no possible dead ends. Since this is clearly an issue, I wonder if it's possible to come up with puzzles that always have a solution similar to how the algorithm for creating Sudoku puzzles always guarantees it can be solved without guessing.

immibis•3w ago
There's a dead end in today's puzzle, if you make TIGHT instead of RIGHT, and the hint will tell you you're at a dead end.
latexr•3w ago
It’s stuck at “Loading…” on both Brave with no extensions and Safari with adblockers. It was only after I tried it on Firefox without anything that I realised the cookie banner is the issue.
perlgeek•3w ago
In Firefox with ublock origin, I got in the console:

"Loading failed for the <script> with source “https://uncrossy.com/js/cookieManager.js”." looks like a false positive in the ad blocker. Allow-listing the site fixed it.

T0Bi•3w ago
Same on brave when block is enabled. I think it's because of the cookie banner.
jnovacho•3w ago
In tutorial, it did not accept HIM as a solution, because it wanted DIM. Kinda confusing.
tobr•3w ago
You have to form a new word. It starts as HIM.
xibbie•3w ago
The finishing move on Jan 1st was gorgeous, nice work!
earlyriser•3w ago
Yes, it was a complete wow moment.
knuckleheads•3w ago
thanks for your comments, got me to play that one, and it's great. very well done!
moritonal•3w ago
Okay, amazing. (https://uncrossy.com/index.html?p=2026-01-01)
alvsilvao•3w ago
Cool game!
glkindlmann•3w ago
The website says "I basically need to design puzzles in reverse and have built a set of tools to help me with that." Does that mean that each day's puzzle is essentially built by hand? It seems like an interesting and non-trivial search problem to automatically generate puzzles, given a dictionary.
rjagnow•3w ago
Uncrossy creator here. Yes, I design each by hand using a highly custom editor that I built to help with many of the common challenges. People keep asking me if it's a job that AI could do, but I think it would be really hard to get right. There's a lot of craft in building the shape of the puzzle and picking words that allow as many spaces as possible to get filled in.
glkindlmann•3w ago
That's super cool! Thanks for explaining. Just to clarify myself - when I was thinking of automation I was not thinking of AI, or at least not how its popularly understood these days. I was thinking more like how 2D mazes can be automatically made by non-AI methods. Uncrossy would need a kind of constraint solver that can navigate words lexically and the spatial intersection of words (and their possible slides). I'm certainly not telling you anything you don't know. There are some algorithms for these (general) kinds of constraint satisfaction problems and they long pre-date "AI", but I think the application to uncrossy and refinement would be quite challenging.
phyzome•3w ago
Oof, visiting the settings page means you lose your place in the game.
2bird3•3w ago
Nice concept! A lot of modal spam could probably reduced, very distracting.
causal•3w ago
My friends love this game, but we've found a bug: The reported time in the win modal differs from the time copied to clipboard when you share.
