Hi! I'm looking for test solvers for the upcoming German Sudoku Championship. If you are interested, please let me know, preferably via e-mail: uvo42@gmx.de The championship will be held online, open to everybody (there will be an official German and an unofficial international ranking). Test solver...

Roland invented a puzzle type he named corridors:

With some minor changes (regarding the sizes of the regions) it was used in the WPC 2013.

It is probably the printer. I've had the same experience before, printing pink usually means you have to refill cyan ink.

This weekend the online qualification round for the German Puzzle Championship takes place. The online round is open for everybody. The contest has already started and will end on Monday at midnight (CET DST). http://www.logic-masters.de/LM/qualifikation.php?chlang=en In the instruction file, some g...

I expect the puzzles to be a lot easier than in the previous round; my guess is, total points / 10 equals the time in minutes that is expected from the top solvers. Last year, every round was normalized to 600 points, and the target for the puzzle authors was a round that could be finished in 60 min...

I did, and I have no idea how to solve them in a reasonable time otherwise.

There is no such thing as a best solution. If your puzzle has five solutions that meet all conditions, it doesn't matter which solution you had in mind; all solutions are created equal.

Stop making these announcements, please. Show us one of these supposedly hard puzzles or don't, but the way you present yourself at the moment is just annoying.

Congratulations to James for another clear win!

Contest has started. Enjoy!

An updated version of the instruction booklet has been uploaded:

- The Divide and Conquer example had two solutions, which is fixed now.

- The rules for Plates and Doors have been amended: "In the beginning, all doors are closed."

Thanks to kiwijam for noticing.

To pay homage to this great contest series, I have prepared another contest: Best of HCS It consists of 12 puzzle types, one from each HCS contest, with one or two puzzles each. The instructions are available both in German and in English. The contest runs from May 30 to June 2 - the upcoming weeken...

I wasn't sure about the upper half, but for the lower half there is only one solution.

There are a few more German puzzlers who have been to the IMO - Martin Merker, Philipp Weiß, Georg Schröter (AFAIK).

I am using Foxit as well, and it works fine for me.

Thank you!

Just to make sure - the instructions are also available in English.

I find the nurikabe was very easy, considering that each letter was part of a different name. and yes, every name had to form a snake like strip. The assignment of PAL and BRAM were immediate, shortly after NIKOLA; then the pair ULRICH and HIDEAKI, then the others. Definitively not worth the highes...

Not yet, but it will be soon.

The online qualification round for the German Sudoku Championship will take place this Saturday: http://www.logic-masters.de/DSM/qualifikation.php The instruction file contains examples for all types of Sudoku variations that may appear (some variations mentioned there will only appear in the offlin...

This was the WSC, not the WPC. What euklid wrote is correct.

These three hour sessions will almost certainly consist of several rounds. In fact, I do not recall a single three hour round in any WPC since 2000; there may have been 150 minutes rounds, but very rarely. A typical WPC consists of: 2-3 long rounds (90-120 minutes), several intermediates (about 60 m...
