I had a question on Hitori Chess.... in the example each chess piece attacks one number... however, can a piece attack 2 numbers in one line as in the example for Hidden Words... I am attaching an image of an alternate solution for Hitori chess.... Im not worried abt the dual solution of hitori chess in the example but want to confirm if the rule of hidden words (where the bishop attacks 2 Es in one line ) is also applicable in Hitori Chess.

In the attachment, one of the 4s in row3 has to be painted black. So it is not a valid solution.

sorry, I attached a wrong image... The correct image I wanted to attach is below...

As per rules, the example has more than one solution.

Please note that some of the examples are just for illustration purpose, and may not be valid puzzles by themselves. (Nikola mentioned this in IB )

Thanks, Rishi. Yes, we have a dual solution here but I'm glad that you understand the rules. As I said in booklet, this is not a puzzles.

In Hidden words, can the words be spelt in reverse??

Rishi

That is not allowed.

In Battleships, can a piece attack the same ship more than once? (Say the knight attacks two cells of the 4-cell ship)

Yes..........I think so.........because the instruction

each chess piece attacks exactly one ship of every kind

It dosent talk about the number of ship segments.......

That is allowed.
A chess piece can attack same ship more than once.

Puzzle booklet is uploaded

Now this was a completely new and refreshing set of puzzles :)

Though I am familiar with chess but never ever imagined an influx of chess into our normal day to day puzzles....

Great set Nikola... though not much to look forward to from my results point of view...

Rishi

grt set of puzzles..........very difficult from my standard....thanks

Great test !

Unfortunately I entered coordinates in alphabetical order instead of top to bottom for chess battleships and hidden words...
(I think the order required is not specified for hidden words.)

thanks for the puzzles

Fixed. Please check.

Wonderful puzzles! I love one more time your Tapa Chess. Thank you very much Nikola. I hope you keep the competition, Chess 2:)

Hi
During the last 3 minutes, I solved the Filomino Chess...
And when I clicked submission nothing happened.
I rated all the puzzles and re-submit each answer, still, nothing happened.
When the time was up, the page froze for the next hour and a half.
Now, I looked at the results to find that my Filomino-Chess and puzzle ratings weren't taken into account.
Could you somehow check this for me?
I sent you my answer to Filomino Chess, if its right then maybe is it possible to compensate for the frozen webpage?

Great puzzles.
Thanks for the great hosting.

Thanks for the beautiful puzzles.

1 minute before the end I finished a puzzle (on which I was working for 15 minutes), made some basic checks about the correctness and entered the solution code. Since I had 20 seconds to spare I continued checking the puzzle, and found one mistake! I needed exactly 17 seconds to correct the puzzle and the solution code. Thus I used the time perfectly with 3 seconds to spare. :-)

Of course I left some puzzles untouched (although not too many), but I could correctly solve all the puzzles I tried. Perfect test and good score for me!

Hi,

It was great set of puzzles, Due to project release I could not take the test early, atlast I made it.

Made simple mistake in Snake, first digit supposed to be A but entered B.It was Really Tough.

3 Cheers,Keshav

Great set of puzzles, handicapped only by my inability to spell and count... Tough but great fun. Many thanks!

I entered the weekend not expecting to find time to do this set, but I'm glad I carved out a chunk of this morning to do it. Really tremendous set of puzzles. Some of the older known variations (Chess Battleships, for example) solved very nicely while the new additions like Tapa and Fillomino were phenomenal. I simply wish I didn't make my classic Tapa error (thinking I was done before the whole thing was connected) on the first go around. Thanks Nikola!

Edit: Oh, and on a general site comment, the "discuss" button at the top of the results page should open in a new tab (if possible) and not load directly on the same page. At least if you are enforcing the 30 minutes penalty. Since now I have to wait 30 minutes to look back at the results again although I got a quick glance.

Another enjoyable set - I will now endeavour to complete them! My answer for ChessDoku doesn't seem to have registered (submitted with about 5 minutes to go) - unless I got it wrong and it therefore isn't appearing in my results section.

Congratulations to Ulrich, Thomas and Phillipp for topping in Puzzles & Chess.
Ulrich finished all puzzles in incredible 47 minutes ( may be because he is strong Chess player :-)
They are the only 3 players to complete all 10 puzzles.

We had 81 0+ scores out of 113 participants. The general puzzle difficulty level was bit higher than few previous tests, that might explain the unusual high number of 0 scores.

As everyone mentioned, the puzzles were very very well written and most of them were innovative too.
Thank you so much Nikola for the wonderful set of puzzles!

It looks like a connectivity, there is no entry registered in database for ChessDoku.

Yes, we'll have that next time.
But it is definitely best to get rid of the '30 minutes constraint'
