Hello everyone,

almost a year later, I thought I'd ask here as well...
This time it's about the online qualifier for the German Puzzle Championship. If you are interested in test solving and have time within the next two weeks or so, please send me a mail: hausigel@gmx.de

Thanks in advance,
Roland

Many thanks for a beautiful contest, David.
My favorites were the Sums and the Consecutives. To be honest, I was a bit skeptical about the latter (usually I prefer this variant with full information, i.e. all possible circles are given), but it turned out they had nice smooth solving paths.

Skyscrapers - oh happy day!

Hello, as part of a beginner series I have posted a set of Fillominos - including a guide to solving techniques - on my blog a short while ago, and I am happy to share them here: https://hausigel.de/blog/2020/06/20/classics-collection-fillomino/ https://www.hausigel.de/blogdata/cc_6/Fillomino.pdf Th...

I received a message that the GP website uses a certificate which has expired on August 22, but told the browser (Firefox) to continue and accept the risk, which worked for me.

Thanks James, Liane and everyone else - I am glad to hear that you enjoyed the puzzles.
The scoring is finalized; everyone who didn't have the chance last weekend can start the contest now.

The contest hast started. Have fun!

Hi folks, you are hereby invited to take part in our annual Skyscrapers contest which takes place this weekend (only Saturday and Sunday, 48 hours in total) on the German web site. You will find more information in the German forum. Sorry for making this announcement at such short notice - I hope yo...

This is actually a flaw of the Sudoku Solver you are referring to: The step where it excludes the other four solution is critically based on the assumption that the solution is already unique. But since the assumption itself is wrong, the outcome is meaningless. Basically, any argument based on an i...

It doesn't matter if you write "best", "strongest" or whatever. The puzzle has five correct solutions, and you are simply wrong to assume that one of them is preferable to the others. Uniqueness can only come from an additional rule , but since you are not providing one to resolv...

Hello,
the scoring table is now final, the contest can be started again (but new results will not show up in the table).
Once again thanks to all participants; congratulations to uvo an to the runner-ups.

Hello,
the scoring table is visible now, but changes are still possible. If you want to request a score adjustment, please send me a message until Wednesday.
In any case, many thanks to all participants.

Hello, the Skyscrapers Contest will start in a couple of hours. A few last-minute remarks: Please note that there is a time change this weekend. Incorrect solutions which are - based on my assessment - only due to typos will be corrected directly; in unclear cases I will inquire via email. (Please c...

The points for the indiviual puzzles have changed (sorry), I have uploaded the new versions of the contest files.

Hi folks, the sixth annual Skyscraper Puzzles Contest will take place in two weeks (Oct 25+26). The contest will run two days in total, the solving time for each participant will be 120 minutes. The instruction file is available since today; you are welcome to ask questions in this forum. I haven't ...

... by Richard Stolk, actually.

Hi,
the discussion of the first DP week (including solving times) is now available on my blog. Many thanks to James for stepping in as the first expert.
Hausigel

Hi there, thanks for your feedback. I find it counterproductive to release expected solving times before the actual solving; many solvers - including myself - adapt their solving strategies if they know what time to expect / to beat. Thus I am planning to publish the expert's times after each week o...

I rarely use any other browser but Firexox, but I visited a java applet forum and was led to believe that it should work on other browsers, too. Very sorry about the inconvenience!

Hi, the test phase of the Daily Puzzle applet ends tomorrow; the DP officially starts on Monday (September 1st). In case you are not able to solve the puzzles on the respective day, they will remain available in PDF files (probably delayed by a couple of days). Furthermore, a weekly discussion of th...

Hi folks, there is a new section on my homepage which includes a Daily Puzzle which can be solved in an applet (follow the link near the bottom of the page linked below). I wrote the applet myself; it is not signed, so your browser might send you a warning which you have to override manually. If you...

Hi there, I worked hard to make sure that the "No Four in a Row" puzzle wasn't just an exercise in searching for three identical symbols in a row. Many puzzles of this type include only this kind of step; let us call it a "one-stage" reasoning. The intended solving path for the c...

Looks interesting. To clarify, the Rallye mode means that the total time begins on 24/12 for everyone (not when we click the Start button), and also we can (re)submit answers without penalty and see our current score on the Ergebnistabelle. Is that correct? Pretty much. You should not view it a con...

Hello, I have set up another contest on the LM initial page, "Dream within a Dream". The contest takes place in "Rallye" mode, which means that there will not be a short time window for solving the puzzles; the contest will run over a year in total. Since I designed the puzzles a...
