I was thinking to share some cool problems that users have been posted with my math class. I also would like to include some problems in a computer game I'm developing. I was also thinking to post them on some other forums.
I wanted to ask how the problems are licensed?
I'm also aware that some problems here are taken from somewhere else, some problems gave credit to their origin and some did not. What about those that did not give proper credit to their origin, i.e. we don't know if they have a foreign origin?

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

You are definitely welcome to share problems from Brilliant with your classmates!
When sharing problems, we encourage you to use a link back to the original problem, so that it allows them to engage with the rest of the community. This can be easily done through the share options on the problem itself.
For licensing questions (which always involves lawyers) -- please refer to our terms of use.
TL;DR :- I'm not an admin, but I'll try to answer. You most probably won't have to ask to take questions from Brilliant if you're using it for non-commercial reasons. Most people won't care about you taking recreational math problems. Even fewer would do anything about it.
From a legal perspective, (Also not a lawyer, so don't take my word for it), it depends on the questions you want. I doubt most of them would pass the threshold of originality. On the off chance they do, it depends whose question it is.
If it's Brilliant's question, i.e, the practice questions, wikis, or problems by the admins, then Brilliant owns the license to these questions. To use them without liability, you would have to ask them for the right to use it.
If it's a user's question, then Brilliant assumes the the license for the question lies with the user, and when the user posts a question here, the user is authorizing Brilliant to use it .As you correctly reason, the user most likely doesn't hold the license. In that case, when the user uses this site, Brilliant disclaims all liability and the user is liable to any legal action. To use these questions without liability, you would have to track down who holds the license to that questions and ask them for permission to use the question, or would have to do the same thing Brilliant does, i.e., push all the liability on the submitter.
