It was 10°F this morning in Colorado so it's probably time to put out our Winter 2013/2014 quarterly. In this puzzle you'll find some Trividoku, Stars & Stripes puzzles and also a few Atlantis style puzzles. Additionally you'll see a few more puzzle styles we're trying for our next book, Sudoku in Wonderland.

The Quarterly is here and is about a 600k PDF file. Enjoy!
