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.

If you're on android check out the puzzle suite app on fdroid

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.

If you like doing long paper working, a youtube channel called mind your decisions has a vast wealth of problems. Some of them are duplicates with different variables. If you turn on youtube history you can effectiveky mark off how many you have solved.

I think scientific american has short maths and logic puzzles publiahed maybe weekly or daily. https://www.scientificamerican.com/games/math-puzzles/

Also shout out to cryptogram/cipher style games, which i see as reasonably mathematical

https://cyphrgame.com/ https://decipher.wtf/ https://cryptograms.puzzlebaron.com/play.php

I think the puzzle baron one might be dominated by bots because it has solve times of 1 second listed when i do it.

The @daily_fourmula@lemmy.ml bot posts math puzzles daily to !dailygames@lemmy.zip

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.
