I’ve started compiling a list of interesting Math problems and riddles spanning Probability, Geometry, Logic etc. along with my solutions for them. My sources currently are FiveThirtyEight’s The Riddler and The Guardian’s Alex Bellos’s Mon Puzzle. My submissions have also been featured on The Riddler!
