My best puzzle friend Arvid Baars (Eisbär ) and I have made a sudoku-advent-calender in the puzzle portal of Logic Masters Germany. Every day one of us will publish a sudoku variant that has not appeared in the portal so far. The First puzzle was published on december 1st, the last one will appear on december 24th.

This summer we were thinking about a theme for the calender. Around the same time there was the ‘Classics vs Innovatives’ sudoku test here at LMI. We were suprised and amazed about the fact that still every now and then a new variant to the famous sudoku appears on the internet or in a contest. Unthough there are already a lot of different sudoku variants in the portal of LM Germany, we found lots of sudoku variants at different places that had not appeared yet in the portal. So we assembled a calender with 24 nice sudoku variants; some ideas came straight from other authors, some puzzles were inspired by others and some inventions are from us. We didn’t do an exhaustive search on the internet to find all possible sudoku variants, so we don’t claim to have invented new types, although I am pretty sure there will be some new things in our calender.

Meanwhile the calender has started with the following puzzles:
1.dec: Thermometer sudoku
2.dec: Search nine sudoku
3.dec: Quad max sudoku
4.dec: Odd max sudoku
5.dec: Toroidal Bricks sudoku
6.dec: Rank sudoku

I hope you will try some puzzles and enjoy them!
I will keep you all informed about the coming puzzles by updating this thread.

Once again I would like to mention what a great inspiration the LMI sudoku test 'Classics vs. Innovatives' has been to me. Today's puzzle in the advent calender is a Between sudoku from that test. I only adjusted the lay-out, so it would fit better in the series.

Links to the most recent puzzles:
13.dec Pinocchio sudoku
14.dec Outside twin killer sudoku
15.dec No three in a row sudoku
16.dec Between sudoku

Have fun with these new puzzles again!

Hi puzzle friends,
Today the last advent sudoku appeared, the calender is completed. I like to say once more how the tests here at LMI are a very great source of inspiration for me. LMI is a vivid place with nice puzzle ideas from various authors, that are for sure inspiration to others. I hope to enjoy that for a long time to come!

Links to the last puzzles:
21.dec: City construction sudoku
22.dec: Rhombus sudoku
23.dec: Domino sudoku
24.dec: Clone sudoku

Also on behalf of Arvid I can say: It was a pleasure to make this calender!

Have a nice Christmas!

For those who aren't LMD-active. I've combined all 24 puzzles into this PDF file.
You can save/print it at http://roygbivpuzzles.wordpress.com/2012/12/30/dutch-sudoku-advent/

(Am I allowed to do this? If this is inappropriate/illegal I'll be happy to take this down.)

I hope people who sovled the puzzles will enter the solution codes and/or some comments on the actual website of Logic Masters Germany, links provided in the threads above.

I was just about to ask if a combined pdf is available earlier today, because if at all I solve Sudokus non-competitively, I like solving as a set :P Thanks Tawan, and Richard for allowing it. I'll get it printed and go through them on New Year's day

One of the solvers pointed us at a small mistake in one of the puzzles. In sequence roundabout there was an arrow missing. Meanwhile it is repaired. Here is the link to the corrected puzzle.
@Tawan: maybe you should correct it in your booklet too.

I had a few unused puzzles for the calender; they are published now.
Outside twin killer
Between sudoku
Coming friday there will be one other 'Leftover', it will be the last one.

Shortly we will be starting to think about a brand new version of the calender. Any requests?

I always thought Advent Calendars with 24 doors are outdated. Something like 300 feels more appropriate ;-)

Advent Calender 2014: Double Dutch Sudoku Advent.

We would like to inform you all about a unique Sudoku advent calendar that I created together with my good friend Arvid Baars for the puzzle portal of Logic Masters Germany. We have chosen 12 very well known sudoku variants and 12 much less known variants. Every day we combine two of these in the schedule AB - BC - CD - ... - LM - MA. We believe that combining variants leads to very interesting solving steps, which really adds to the solving fun. We provide solving hints every day too, that might help you getting started.
