From 1st-24th of December, Richard Stolk and Arvid Baars of Logic Masters Deutschland dished out one sudoku variant a day. The 24 artistic puzzles are of very high quality. If you’re not active on LMD, I’ve gathered all 24 puzzles into one neat pdf package you can click right here.
Edit: 31/1/13 – New file uploaded. A minor mistake in Puzzle 19 was fixed.
I am gingerly working on future puzzle projects throughout 2013. Announcements will be made when I’m happy with them.
I wish you all prosperity for 2013 and have a Happy New Year!
