If you haven't already, check out https://projecteuler.net/ https://projecteuler.net/. It's a huge collection of logic problems of varying difficulty that require a mix of math and programming to solve. There are 723 problems at the time of this writing, and a new one is added each week. After solving a problem (you need an account to submit solutions, but can view all problems anonymously), you get access to a discussion thread where you can gawk at the often mind-blowing solutions that other solvers have hacked up in all kinds of languages.
