Hewo. :)))
One of my recent hobbies is to solve puzzle hunts with my friends.
If you're bored, I highly recomend doing some.
I figure that if you like math, you'll probably like this too.
Here's a list of puzzle hunts.

They can take anywhere from 5 - 100 hours depending on your skill level and the hunt.
