Are there any good math puzzle sites or apps?
I remember doing combinatorics puzzles and number theory exercises in platforms like Brilliant when I had a bit of free time. All the while learning something. But the last time I tried Brilliant I did not enjoy it as much and I can't afford it not anyway.
Does anyone have any recommendations of websites (or webrings), apps or games about or that touch on:
- combinatorics puzzles
- modular arithmetic puzzles
- concepts or exercises of number theory

Nerdle is a daily math based worldle that is quite fun IMO.
The problems are designed for programmers, but Project Euler comes to mind.

If you like geometry and trig, the apps Pythagorea and Euclidea are very fun puzzles. They're free and there are hundreds of puzzles. They get very difficult.
The app Mental Math actually improved my mental math indeed! While division can typically be estimated because it never goes into mixed numbers/fractions, it does eventually go into 5 digits' worth of all the 4 basic operations; you set the difficulty and climb as you like. I'd never multiplied so accurately in my life, haha.
i like simple math, i love this app. just cruise through; even has tutorials for tricks and stuff.
its called FastMath
