Made a free mental-arithmetic game — would value teacher feedback on whether the difficulty progression actually makes sense
I'm a solo developer, not a company, and I'm not selling anything. The browser version is free, no ads, no sign-up. I'd rather get this wrong in front of teachers than in front of students.
What it is: a target number and a pool of numbers. Combine them with + − × ÷ to hit the target exactly, using each number once. Essentially the Countdown numbers round, or a cousin of the 24 game. Sixty seconds a puzzle.
Why I'm posting here specifically: I built it for general players, but the feedback I keep getting is that it's most useful for kids building arithmetic fluency and number sense. I don't have a teaching background, so I honestly can't tell whether the progression is pedagogically sound or just feels right to me.
Three things I'd genuinely like your view on:
There are four difficulty levels. Do they map onto any sensible age or ability bands, or is the jump between them arbitrary?
Is the 60-second timer helpful for fluency, or does it just manufacture maths anxiety? This is the one I'm least sure about and the easiest for me to change.
Would something like this work as a lesson warm-up, or is the setup cost too high to be worth it?
Being upfront about one thing: the Android app is ad-supported. The browser version has no ads and no login, and that's the one I'd suggest for anything classroom-adjacent.

Happy to answer anything, and equally happy to be told it isn't useful.
