Also, 4 becomes 7 and vice versa. Same with 6 and 9.
Remaining digits 0 1 5 8 don't change when turned upside down.

In Superimposed Loop, can both the grids contain a black cell in the same position?

Indeed. Just their superimposed form is given, the two grids are actually independent. They do not put any constraints on each other.

Small clarification: Sorry for making the diagram borders bold on the Symmetric Loop example, it led to some confusion with the actual regions. Contest puzzles do not have them bolded.

Puzzle Booklet uploaded. It has 11 pages, each page has puzzles (no cover page)

Starting this test, we are making one change
If somebody doesn't want to include this test's results in LMI Ratings, they must unselect the checkbox.



After clicking on "Start", the checkbox will be invisible.

To add to what the Admin said, if a player does not uncheck the box then irrespective of whether they submit the answers or not, their scores will be taken into consideration for the ranking and that can affect their standings too.

Thanks for a very fun test that went by too fast (I guess 101 is a rotationally symmetric number of minutes, but I think we'll all comment that we would have loved more time to be MAY-nipulated). Still, I worked a little past the test to finish everything up and enjoyed it all.

I'm really glad if it was enjoyable. About the time limit, it was adjusted from the times of the test-solvers (many thanks to them). Competitively solving must be more stressful though. I also have to say that some of the harder ones are difficult to start, then goes smoother. This may cause loss of time as well.
Anyway, thanks for the nice feedback!
Regards,
Murat

Very nice puzzles. Among the ones I could solve, I liked deformable kropki (bottom) very much - Kropki can indeed be fun with hidden black dots, although it took me quite a while to get the right idea.

I don't know that 1001 minutes would have saved me today. Fortunately I have a rather large set of enjoyable looking puzzles to dive into tomorrow. Thanks Murat.

Similar sentiment from myself as well I'm afraid. Too many silly mistakes, including counting the bottom line on one of the corral instead of the one above it. STUPID me!

Thankyou for a great set of puzzles, sorry I couldn't do them justice.

@standupcanada and puzzlemad: I'm sorry things didn't turn out as you had hoped. I should be the one thanking. Thanks for participating!

Wow, that test really played to my strengths. Spiral galaxies, all kinds of path puzzles, grid jumping... just the Kropki and Skyscrapers that threw me a bit. Great fun!

Thanks for the test. Very nice puzzles.

I have solved the bottom puzzle of "First Seen Corral" correctly but entered the wrong solution code. If you look at my answer you will surely see what I did wrong and that my answer key fits to the correct solution of the puzzle. Actually I can give a good reason why my (wrong) way of entering the solution is actually the correct one. :-)

As I recall from earlier events, full points were awarded when entry mistakes happened and it was obvious that this wrong solution code fitted to the correct solution (e.g. entering the wrong row in a sudoku). I kindly request you to do so for my "First Seen Corral". If you cannot see my point or doubt that I have actually solved the puzzle, please write me a PM.

Have fun,
Stefan (euklid)

MellowMelon, I'm glad it did. Thank you!

euklid, I have sent you a PM, please check.

could you please double check my solution. I entered the solution to the first deformable kropki with about 1 minute to go but the system has registered my last submission with 15 minutes to spare. Something must have gone wrong.
my server page is still open and says "An error occurred while submitting. Please try again" and the server time is 8:00:49 (local), 7:00:49 GMT.

Hi forcolin,

I checked your standings. Your last submission is 99:59 and you have indeed received 35 points for the first deformable kropki.

Murat

Excellent 'difficult' puzzles. Many times, there are difficult puzzles where the toughness tends to diminish the fun of solving it. But this test had the 'other kind' of difficult puzzles in which the toughness added fun of solving. Lot of brainwork used for this test, and loved the puzzles (most of which were solved after the test ;-) ) Thanks and hope to see more from you in the future.

Thanks for the compliment Rohan. :) I'm glad I was able to make the harder ones enjoyable.

thank you Carton Mutant. Noticed the change, I thought it was an effect of your amendment. perhaps I checked the results only seconds after the end of the contest and the result shown did not keep into account last minutes submission.... Deb is this possible? of course then I could check again only after 30 minutes.... Thank you for checking anyway.
very good set of puzzles, very challenging and of excellent quality. thank you, and congratulation for your success

Well, that was not my doing but I'm glad you got the points you earned.
Thanks for the kind words! I'm happy you enjoyed the set.

Enjoyed the test, ACM - thanks for your time and effort! Best regards, Dave

Welcome back Dave! Haven't see you at LMI for a while!

Enjoyed the difficulty level of this test! But... I cannot understand why my answer to Spiral Galaxy I is wrong... as far as I can tell, the answer I have is correct (although I am tired! it's late here!)

Perhaps I misunderstood the answer key?

Edit: hehe sorry, I typed the answer key with one too many repeats... will you consider a correction?
Thanks :)
Ronald
