Websites with different types of problems to solve. Doesn’t necessarily need to be programming or math, maybe something similar would be a daily reading challenge or a vocabulary quiz.

Only a few problems here but they are very hard, and they pay you $1 million for each one you solve: https://www.claymath.org/millennium-problems/
Only one person has solved one so far, and he turned down the $1 million. Go figure.
For programming, try rubyquiz.com. It’s supposed to be Ruby exercises and some of the problems are Ruby specific, but lots can be done in any language you want.
I was showing a student the Collatz conjecture last week. It would be a nice way to enter the millionaire class.
