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!<p>Every puzzle is solvable and has at least one solution (usually more).<p>There is a kids mode in the settings, plus a hard mode for extra difficulty.
> <i>I made this game for my children to play</i><p>Mathematician here. It's fun, but it's quite hard! How old are your children?<p>[spoiler alert?]<p>I finally solved it in 4 steps. It needs a lot of backtracking planning. I has to guess which will be the last expression and try to reach the numbers that it used.<p>I don't play too much Wordle, but my approach was just trying to find a word that is not to stupid (like reusing a lot of letters that are already grey) and just hopping that that the new info will make the next step easier.
Quite hard dude! I'm still going at it. Once you put down an equation like 100x3=300, your mind becomes committed to it...which biases your future choices & quickly leads you down the wrong path.
Awesome game. Pls compile stats on average solve time. I'd be interested to know how long it takes to solve the daily summle on average (aka how dumb am I compared to rest of population )<p>You have +,-, * ,/. But no ^. Why ?<p>I used to ask a^b * c^d=abcd as an interview question. In most programming languages its a 4-line nested loop to find the unique solution.
Nice, very similar to countdown. If you've not seen it then '8 Out of 10 Cats does Countdown' is a great comedy version of the classic show on Channel 4 in the UK.
Nice work! The Countdown model works well for this format. Best maths Wordle variant I’ve seen so far. The video really helped to see what to do (minor point: had to scroll down to see numbers on my phone). Did feel a little cheated when my iteration was locked in as a solution and I could immediately see an improvement!
Pretty fun, few comments
1) The Share Results currently includes a few spoilers as it shows that the player has included the result of one of the previous steps. This makes it considerably easier for someone to get the answer.

nice! instant throwback to childhood watching Des Chiffres et des Lettres on TV<p>a bit of feedback, can you make it so that if you type an operation on the first block of a line it takes the last result as the first item and fills the op as the second item?<p>the thing that trips me up playing is thinking like:<p>"50 plus 3 is 53, minus 7 is 46, times 3 is 138"<p>so I'd type 5 + 3 - 7... i.e I press the operation right away instead of typing the last result before the op... oddly frustrating! and I keep on doing it over and over again!<p>oh, and I second the request to clear the board, reloading just doesn't cut it: it's a full, slow enough RTT to the server that I type on all inputs to clear them up instead. plus when added to the home screen as a web app on iOS there's no way to reload except killing the app... a bit frustrating also!
Nice one and an interesting twist from the classic Wordle. If I may one small suggestion, please add a clear and/or backspace button. Like the buttons present on most real calculators: CE (current entry), C (clear), AC (all clear). I know that you can click on an occupied cell and clear it, but backspace is more convenient :-)
[Spoiler alert] Terrible brute force program in JS says there is (possibly, didn't prove it) 6368 different solutions: <a href="https://gist.github.com/mvladic/9b2f2025a8c54aca78649ce1776600b6" rel="nofollow">https://gist.github.com/mvladic/9b2f2025a8c54aca78649ce17766...</a>
I found a "normal mode" solution in a couple minutes after some trial/error. But then I spent 10 minutes trying to find a solution in "hard mode" to no avail. I ultimately gave up and wrote a recursive solver in python. Now I feel better about myself and can continue about my day.
I really like this and find it much more engaging than mathler, which is my current favorite (nerdle doesn't really do it for me).<p>The difficulty levels seem right for my level at least - kids mode was almost instant, regular took a bit of thinking, advanced still has me stumped:(<p>Please consider a "clear all" button. I know you want to keep the UI simple and that I can refresh the page, but this seems like an omission considering how much trial and error I'm doing on advanced mode.<p>Also, maybe an "I give up" button, hidden somewhere in a modal. I suspect I'm not going to have time to solve this before the next puzzle comes along, but I still want to know the solution.
Consider a mode with limited uses of the operations too. I liked it, but I thought both normal and hard modes were too easy given I didn't have to think about what operation I was going to use at all.

=<p>I like it. Some UX tweaks would be nice, maybe an undo, a clear all, and perhaps some helpful focus shifting (of which tile is being intended for a click) depending on context.
This is brilliant, but impossible to learn how to beat on Hard mode without programming brute-force recursion. Even when we factorize the target number and its neighbors.<p>a) Can you publish daily solutions to yesterday's problems? I'd really like to see the solution to #8-Hard (1,6,7,7,50,100 Target: 875)<p>b) Can you add links to archived previous problems?
Well hello. I was in the middle of making a game with a very similar premise lol, apparently a few of those are around, but I do think the Countdown gameplay of 6 numbers is 'too difficult', you can't make poor guesses and still win like in Wordle.<p>How does the "app" feature work? Was it easy to make (given a static site)?
I clicked through and then immediately forgot the instructions so I tried to go back to read them. Now the button just says "Come back Tomorrow" and I can't even play. Stopping a person from playing again does only bad things for user experience. Please consider just not doing that instead of doing that.
Actually, it isn't that hard (took me about 5 minutes to arrive at the 3 steps solution). Especially with a number like 486 which you might have met in school, when learning multiplication... Then again, I like the mental exercise :-)<p>Edit: And another 6 minutes for the 'hard' version (4 steps).
I think I was a bit lucky, but solved today's (#8) optimally in a minute or two.<p>Pretty cool puzzle, reminds me of this: <a href="https://blog.plover.com/math/24-puzzle.html" rel="nofollow">https://blog.plover.com/math/24-puzzle.html</a>

=<p>Is "hard mode" based on difficulty judged by a solver? It feels like something that would more easily differentiate the modes would be adding extra numbers instead of 6 for all modes.
It was not clear to me that "the" solution didn't require all the tiles.<p>Or that there were multiple solutions.<p>In the end, I did all the steps in my head, and then refreshed the page to do it in 3 steps.<p>But it's not really an "iterative" game.

Got very intersted, then lost interest because I couldn't reload and get a new number when I was sure I had taken the wrong path. Is there a feature to start again from a new random number?
I built one less challenging in Java some years ago.<p><a href="https://github.com/teni/sumgame" rel="nofollow">https://github.com/teni/sumgame</a>
