I have shared quite a lot of sites in this blog about places where you can find challenging math problems for your intellectual satisfaction. In this post, I am going to introduce a website called **Brilliant.org**, a problem solving website which provides different levels of physics, computer science, and math problems depending on solver’s ability.

Brilliant.org provides different levels of physics and math problems, from practice to Olympiad level. Recently, it has also added problems in computer science particularly on data structures and algorithm. Math problems include challenges in algebra, number theory, geometry, and combinatorics. Physics problems include challenges in mechanics, electricity and magnetism.

Just like in other challenges and games, problem solved at Brilliant.org have corresponding points. Players can exchange points for corresponding prizes. Players can also discuss problems within the website.
