Last week’s “Windows” variety mix from Prasanna Seshadri can be found in this PDF.

For the last 18 months, GMPuzzles contributors have been providing sudoku variations to the magazines Sudoku Spectacular and Will Shortz’s Sudoku. Some of the submissions are too hard (or too unique) for those publications, and I keep those submissions for our web site. We will have another collection of these “extra” sudoku puzzles next week, specifically:

Monday: Isodoku by Serkan Yürekli
Tuesday: Tight Fit Sudoku by Thomas Snyder
Wednesday: Consecutive Pairs Sudoku by Thomas Snyder
Thursday: Thermo-Sudoku by Prasanna Seshadri
Friday: Even/Odd Sudoku by Swaroop Guggilam
Saturday: Arrow Sudoku by Rajesh Kumar

Our supporters will also be receiving a bonus Arrow Sudoku from Prasanna Seshadri, access to puzzle solutions, and a video walkthrough of the Saturday puzzle. If you’d like to receive some of these special rewards, please click here for more info.
