Earlier quoted context omitted.

The rules are on the info page - maybe not that obvious.

Yup - I skimmed them, so that's on me! Don't let me being relatively harsh discourage you. It's a good, educational game that makes you think. It just feels very different from something like Wordle, and that's OK. Now that I got the hang of it, I tried the easy and hard modes as well, and got them both on the first try without having to undo anything. But as others said, I looked at the available numbers, figured ou…

Thanks, all feedback is most welcome. I tested it with only a small number of people.

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. 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 lo…

Hard? I found the hard one fairly easy, and don’t think I accidentally spotted the solution early. For difficult, I would expect at least one division, as in (ax+b)/(c-d)

But yes, I factored the result in my head. I would have done the same with (result ± any of the other numbers), if necessary.

Also, for the simple one, I immediately recognized 243 as a power of 3, so maybe, I’m not in the target group ;-)

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 )

You have +,-, * ,/. But no ^. Why ?

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.

Countdown was inspired by https://en.wikipedia.org/wiki/Des_chiffres_et_des_lettres#Nu...

I'm still working on the difficulty levels. I think recognising factors of either the target number or nearby numbers is key.
