Hello all. I'm doing a new Sudoku Advent Calendar at The Griddle this year and wanted to invite you all to participate. It's not too late to start - so go grab the grid and the first piece of the puzzle at http://thegriddle.net/tags/advent2013
David is doing a new Advent calendar this year, based on Area 51 (a combination of loop-finding puzzle types), so check it out! http://www.thegriddle.net/
