I wrote a script which generates all possible solutions for a given puzzle.
I made the site a few years ago, but I've refined it and added some features over time. Hopefully it's worth another mention!

I made summle.net a while back, which is similar.
After I while I found that this type of game can be frustrating as you are not incrementally solving the puzzle - instead there are multiple dead ends before stumbling upon the solution.
Today's puzzle was difficult I admit. It's tough to find a balance, I'm still working on it!
Can I ask which device you're using?
I think you meant to post in the thread about the emoji game?
Thanks for the feedback. Re: the scrolling issue - can I ask which device?
Thanks. The 'share results' grid is about as minimal as I can make it without it being devoid of information!
The reset upon completion is intentional, as there is (usually) more than one solution to be found. For the purposes of stats recording, only the first successful attempt is registered.
Thank you. I do actually have another mode planned!
I wanted to keep it to operators everyone would understand, though it would be interesting to use exponents!
I am only recording successful attempts, which for the regular puzzle is around 33% so far today. I might compile stats on solve time too.
I'm still working on the difficulty levels. I think recognising factors of either the target number or nearby numbers is key.
Thanks, all feedback is most welcome. I tested it with only a small number of people.
You can click on numbers to remove them, so that you do not need to refresh the page.
The rules are on the info page - maybe not that obvious.
You won't like the extreme mode I have planned.
The undo function is in the works.. to clear all you can refresh the page (or click the logo). There is an effect when a tile is filled but perhaps it needs to be more dramatic.
There is a kids mode in the settings. Today's one is hard, I must admit (though it can be done in 3 steps) - they did well when I was testing the site!
Indeed. Everything old is new again. There should be 6 numbers - perhaps one is cut off. Are you on mobile?
Thanks. The backspace is something I considered, but it would have to function more like an undo button. You can refresh the page (or click the logo) to clear all the cells.

I made this game for my children to play, as they are heavily into Wordle, and I thought they'd also like something maths based!Every puzzle is solvable and has at least one solution (usually more).There is a kids mode in the settings, plus a hard mode for extra difficulty.
