Hexle is a small number-guessing puzzle game based on Sudoku! Each number can only appear once per line and per 4x4 square, but also binary restrictions apply inside of each square, limiting the numbers that can be placed on any one tile.

Learn Hexle's rules with the game's introduction and then go forth completing generated puzzles in various difficulties. Come back every day to solve the daily challenges or to tackle the weekly 16x16 megaboards! As you complete puzzle grids you will unlock new color palettes to change the mood of the game! (light and dark palettes are available from the start)

You can stop playing at any time and continue your puzzle later. There is one save slot per difficulty which you may continue or reset at any time. The game plays entirely with the mouse.

This was originally Remy's entry for Ludum Dare #54 compo! The Ludum Dare version was made in 48h and had to fit the theme "Limited Space". Here is what it looked like, this version is still available on this page as a free download further down this page!

Can you please make Linux (and MacOS) builds for the main game? It seems weird to have it for the demo but not for the game itself.

We'll get to it soon! The demo version was mostly just a test, but we have the full thing almost ready now!

Oh this game is like 4 months old lol.

Thank you

This game has been invited to a co op sale! https://itch.io/b/2232/christmas-co-op-bundle

my brain is more damaged than my wrist even though it’s only the demo 💀.

worth the money 

This is a great game! Very fun logic with the shared-bits rule. 
There's too much clicking and right-clicking, though, I won't be able to play for long because it's going to give my wrist RSI.

I'd love it if this included some "Good Sudoku"-like tools, and to be able to swipe across multiple cells to add or remove possibilities.

(+1)

Hi! Thanks for the praise and sorry about your wrists! 😅

You can already swipe across multiple cells to remove possibilities, though you'll have to click them one by one to add them back. 🙂

The demo is so good! Hopefully, an Android app will be available.

This is mental

i like this!

very cool and fun my brain is not as big as i think it is but nevertheless i solved some with minimal error! :D

(+3)

Overwhelming at first, but really fun to figure out how to improve and make deductions! I wish I could draw on the screen; I stopped using the game and solved them in paint instead. And then eventually I went back to only using the game, to try to get my time down – here’s my fastest:

hard mode 2:51

What does the daily do? it seems to be completely random puzzles, not a single puzzle per day.

(1 edit)

Really cute puzzle game! Some fun logic going on with the restricted bits and the way you have very few ways of placing 1 - 2 - 4 - 8 and all the 2-bit numbers. You can go pretty fast if you're smart about the way you use the available info. For a first time puzzle game, this is really good I think! Also, love the confettis <3

looks nice dude.

and nice to have a linux build

will have a try

(+3)

Perhaps I've just got a bad memory, but I would have loved a way to note the restricting bits on the outside of the frames. Just keeps me from having to scrub back thru the rows and columns when I want to guess.

(+1)

I ended up with a puzzle during the introduction to Rule 3 that requires the not-yet-revealed Rule 5 to disambiguate. :/ (Unfortunately Itch isn't letting me post a comment with a screenshot, which has since vanished from my clipboard.)

What to say about a Punkcake Game. Nice visuals and VFX, beautifull pixel art, and a very fun gameplay!

this is a really fun take on a sudoku-like game! there's something very satisfying about filling up the 4x4 square.

(+2)

i might have been pampered by modern sudoku games, where clues get blurred once that number doesn't fit - just so you don't have to manually cross redundant clues


Still pretty fun for what it is

Well done !

Thanks for sharing the source too!

I was hoping to play this on macOS, but I’m missing the libs/gifkey.lua and libs/autosnaps.lua files, so I’d be grateful if you could point me in their direction 🙏

Hi! I'm not sure what you're trying to run the game with but unfortunately it was made with our custom engine Sugar which is not available to the public at this time. I shared the source files mostly to comply with the Ludum Dare Compo rules, and so people can have a peek at them, but there's no way for you to actually build the game sorry.

That being said, I'll be trying to provide a Mac version myself soon, and I will add a Linux build today as well!

I see! That makes sense, thanks for the info I look forward to trying the game out

You might also look into installing wine. It seems scary but once installed most windows games on itch should run perfectly (depending on your hardware/osx version). I use wine-crossover installed via brew from Gcenx's cask, see https://github.com/Gcenx/wine-on-mac#macos-catalina-and-later

Neat, I’ll check it out. I’ve used wine in the past pre-Catalina, but wasn’t aware of wine-crossover, thanks!

Hi again, we've just added MacOS support at last for Hexle, so you can check it out now if you still want to. :)

Thanks for letting me know!

Rule 5 makes no sense: how can all of the 16 numbers appear in each 8-number row and column? That's literally double the quantity that will fit. I seemed to solve the Rule 5 tutorial puzzle regardless of this, completely ignoring that "rule"... but the buttons that appear when it's completed are at least half below the bottom of the window and unreadable. (The "restricting bits" thing is NOT explained well AT ALL, but I was able to reason it out. I doubt many others will...) Needs more work to be interesting to anyone other than math/puzzle/programming geeks like myself, and even among us it's a stretch. There's a good puzzle concept in there somewhere, but I'm not about to try to make my own instances of it.

Okay, I think I know what you meant to say with rule 5: no number may be duplicated in any row or column. None of the tutorial levels required this, but the daily puzzle today did. That would be a failure of the tutorial. (Since none of the other rules make any quadrant of the puzzle dependent on any other, this would be a very important rule, and thus especially important to phrase correctly.)

Thank you for providing the source code. I don't have any puzzle games in mind but I plan to make some SDL2 games hopefully some day and this will help me learn.
