A friend of mine on Altitude has his own online puzzle website called
Pathery. The point of the game is to, using a set number of walls (and any of the given terrain), design the longest maze possible. There are small, simple levels, and there are some completely obnoxious levels featuring teleporters to build your maze around. New puzzles are given daily, and you can compare your old maze designs against others once a new maze is up. There's a tutorial that briefly explains everything you'll see on the site.
I'm not very good at the game (namely because I've zero forethought/planning abilities), but I do enjoy the game, and I'd like to share it with everyone.
If you want the site to keep score/progress of what you've done, you'll need to login via a Google G-Mail account (or at least, that's how it wanted me to login).
Have fun!
