## Pi Day Sudoku 2009

by

Remember Pi Day Sudoku 2008?  Well the folk at Brainfreeze Puzzles have done it again!  Here’s their 2009 challenge:

Each row, column, and region contains the digits 1-9 exactly once plus three π symbols.  There’s a printable .pdf file here.

As a bonus, if you send a correct solution in to Brainfreeze puzzles in the next couple months, you’re eligible for a drawing for their book on Color Sudoku!  More details are on their website.

Happy Pi Day Week!

Edited 10/31 to add that the solution hasn’t been posted on the Brainfreeze site yet, but since it’s well past the contest deadline we approved a comment that has the solution (below).

There’s a contest associated with this Sudoku, so we can’t post any solutions [or allow any solutions or links to solutions in the comments] until that deadline has passed (June 1). We’ll be sure to post a link after that, though.

These poor people sound like they’ve taken a beating while the rest of us have the pleasure to solve this at their leisure.

I can honestly say that from what I learned from solving last year’s Pi Day Sudoku challenge has helped me greatly with this one. I am very proud, but I also hope more people submit a solution this year.
