Math books/pages to do for fun

 My mother does Sudoku puzzles almost daily so at one time I bought her a large book that had about 900 problems, 300 problems per skill level (easy, medium, hard). Is anyone aware of a good math equivalent to be done for fun? I'm talking at a calculus or algebra II level. I enjoyed calculus and algebra II (but loathed trigonometry; I'd love to get better at it). Algebra I is just too easy at this point that I can still remember most of it. I wanted to keep the knowledge because at this point I can barely remember derivatives that well and my work doesn't require calculus.

Here are some resources that I use a lot that might be useful to you:

Project Euler is a collection of programming challenges. However, many of them can be solved with math instead of programming. They're fun either way.

A weekly puzzle series, where each puzzle is meant to be solved using some form of math. Most of the math isn't too challenging, but rather tricky.

Quanta is a great publication that puts out science/math articles. It also has a pretty good puzzle series.

These puzzles are meant to be solved using operations research techniques, but calculus, probability, and other approaches can also be used.
