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.
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.
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!
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?

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.
