Zerrakhi is one of several names I use on the Internet, originally a character in some stories I wrote a long time ago. There's more information on the blog.
How I got involved
Arrived at Math Puzzle Wiki via a comment Oscar left on Richard Wiseman's blog (clicked on name). Saw puzzles in need of solutions; thought it looked like fun.
- Contributed solutions to some puzzles, including seven orbs (via Oscar's talk page), five towns, around the world, and several others.
- Some editing to improve grammar, clarity, etc.
- Initiated discussions that lead to creation of Help:Ways to contribute page, etc.
- Started Help:Editing page.
My favourite puzzle on the site is around the world. It is both elegant and challenging.
