Prasanna: this looks like a great set of puzzles! But the instructions for "their universe" are really worded confusingly (on purpose, I assume) -- the "our universe" instructions not only are much clearer but also, in many instances, rightfully avoid assuming that one version is more standard than the other. Perhaps it is not a bad idea to make it clear that there is just one set of puzzles, and that people who like me have trouble with the "alternate universe" instructions should just use the version from our universe and that the other instructions do not actually add anything (except maybe a good dose of confusion)?

Or did I get so confused that I didn't even get *that* right?

Hii!Perhaps you have not noticed the Author's note at the top in 'Their Universe' Booklet ? :

"Author’s Note (regardless of the universe the author is from) :

This Instruction booklet contains the exact same types but just presented in
a different (maybe interesting) way. Consider this as a “Translation” for
another Universe. It is the same contest explained and presented in a
different way, just for fun"

Hi Denis,

Kishore's right. The first page of the "TheirUniverse" IB contains a note with that clarification. Please let me know if that's unclear in some way.

Ok, it's pretty clear, thanks! I did see the note but I was so confused by the whole "their universe" IB that I wasn't sure it would be completely clear for everyone. With this discussion in the forum I think it should now be completely clear.

I'm having trouble understanding the rules to the linked consecutive sudoku. Could you clarify what is meant by "The edges that are adjacent across two different grids"?

The password protected Puzzle Booklet has been uploaded on the submission page.

Notes about Online solving:


1. Players solving online can check the results only after 111 minutes. Bonus will be computed based on last submission time.
2. Hamle Sudoku will not have marking possibilities on the left grid.

Hi Prasanna, the timers on the submission page seem to suggest the contest will only be open on April 19-20, not 19-21 as advertised. Would it be possible to extend the test to also run on Monday as I think was initially planned, since I am not sure I can do it within the currently listed 48-hour window? Thanks, Denis

For Quad Max Sudoku, does the rule imply that if an arrow is not provided, that number is not greater than all the remaining 3?

I think thats mostly an error. We do intend to run it on Monday too like we usually do with LMI Contests now. I missed it, it should be fixed by tomorrow morning (India time). Sorry for the confusion.

No added implications. Only where the arrow is provided, the digit must be greater than the remaining 3. No Min/Max restrictions otherwise.

I also presume THEY will solve THEIR contest.

Will there be a unique classification at the end, including both US and THEM? Or there will be a separate / different leaderbord for each universe? Or the average of the two rankings for each player with his/her counterpart?

Anyways,
Awesome test Prasanna. Thanks for beautiful puzzles.
My favourite: Hamle
I did many mistakes while solving like trio, arrow and had to reprint page. I bymistakely entered wrong answer in classic sudoku dont know how, but corrected it immediately as instant grading is there.
Could have completed two more if no mistakes at start, linked and maxed quads.
But Overall i felt i have improved in sudoku than previous performances.
Thanks again LMI and prasanna. Will have to solve remaining ones later.
But wanted to request that" can we submit the other puzzles even after time is over just to check if its correct or not? - at present it displays cannot submit after 111 min "

A fairly good contest for me. As Aaron says the linked consecutive was a bit vicious and I had to force through the solution and costed me some time.
IMHO The Hamle was the best one, very logically constructed.

That was a feast of sudokus!Last night I was thinking how it would be like to complete all sudokus except the 2 155 pointers and end up with 800 points.I remember number 8 as being the last thing on my mind before I dozed off....
So the first thing I did during the test was keeping the 2 bigger pointers seperately away from the rest and solve the remaining.As I see, this had worked to my advantage.Not sure if I would have touched even 500 if I had got a bit 'greedy' and attacked any of the higher valued ones.
Keep my story aside and the test itself was incredible and fascinating!
Of the ones I completed ,the stand-outs that I liked very much were Palindrome Search sudoku,Arrow sequences Sudoku and Consecutive sudoku in that order.Looking to complete the Hamle and Quad Max later.
Incredible test Prasanna with lovely solve paths in all !Keep up the good work.Oh! should I say this to the Prasanna from the Parallel Universe too?! :-p

I wish I did the Hamle. Tried it after the contest was over and it took 1/2 the time as the quad max, for the same amount of points.

As I see the IB, I believe you've interpreted that numbers must move by a distance of 1 cell, whereas the rules say the movement will be the distance of the number's value. The two 4s in the IB move to R1C1 and R6C6.

Very nice set. But as already pointed out above, the Hamle was (for me at least) easier than the Quad Max and in fact no harder than the Linked Consecutive.
Still not sure if starting with the big ones was a reasonable strategy, but at least I had a lot of fun with those harder puzzles.

Thanks Prasanna (from both universes)!

happens to me too.

Aaron, Hamle is a type of puzzle relatively uncommon. Not surprisingly, puzzle players like you and me find it easier than those who are mainly sudoku players. Hence (i guess) the relatively high score

Yup, this was exactly the reason I placed a high value to it. The logic of "movements" and using the second grid will be new to many. I just compared it to where something like a Tapa being valued higher than something like a Domino Hunt will still make me always go for the Tapa first and mostly finish it faster, the puzzle solvers would find this one over valued but thats part of individual strengths/weaknesses. I just went by tester timings which basically happened to invert (one had the Quad Max being much harder and the other had the Hamle being much harder) and my own feeling and placed the same value to both.

In the IB, the Hamle Sudoku had two given 4s overlapping each other. Is this possible?


As I see the IB, I believe you've interpreted that numbers must move by a distance of 1 cell, whereas the rules say the movement will be the distance of the number's value. The two 4s in the IB move to R1C1 and R6C6.


Thanks Prasanna and Matus,
Sorry, had a mind blank.

I enjoyed the puzzles, but most were not worth their awarded points. I had a feeling that they have the same difficulty. I do not know why, but the three most expensive sudokus (Quad max, Linked Cons and Hamle) were the easiest for me (besides the classics). On the other hand, I had many problems with both Arrows and Trio Sudoku. Also broke Palindrome Search few times, but it was just because of my stupidity, not the difficulty of that puzzle. Anyway, nice test, looking forward to the puzzle PU II.

Dear All,

Can anyone kindly explain, what does the question actually mean for "2 Even 2 Odd Sudoku - 70 Points"; which says

(“Their” Straight 2 Even 2 Odd Sudoku):- There can never be more than 2 consecutive digits of the same parity in a row or column.

What means parity over here? I am slightly lost in here.

Thanks

@shameem
Parity refers to odd (1 3 5 7 9) or even (2 4 6 8) property of the digits.

All the rule means is : There can not be more than 2 odd digits placed next to each other in a row/column. Also there can not be more than 2 even digits placed next to each other in a row/column.

Firstly, I liked the whole idea behind the 'Parallel Universe'. Congratulations !
Anyway, great set of sudokus, Prasanna ! Most were manageable for an average player like me.
Linked-consecutive looked simple, but swept away a lot of time. I had to skip Hamle as I did not understand the rules till the end. So maybe a bit more 'non-standard' and simplified rules for the not-so-easy-to-understand sudokus would be great !

Overall, it was great fun !

Someone, please throw some light on Hamle. I still havnt understood the rules and the anti-rules for starting this sudoku. Thanks :)

Hamle Rules:

It's just one basic rule i.e. It says each given number should be moved that much number of cells as that number's value ,within the grid i.e. not crossing the border of whole sudoku.
After you find new positions , you solve it like normal sudoku. There is no Anti-Rule as such.

For eg: in IB, r1c3 "5" it cant move left or right as not much space, so it can be only moved down. Similarly for r6c4 "5".
Other simple trick is numbers like r6c1 "1", it can be moved right or top so it can be at r5c1 or r6c2 in either case it remains in that 2*3 box. So clue "r5c1" must move to r4c1. This kind of technique is used most in the actual puzzle too.
Hope that helps. :)

(Bit late to get to this due to getting PU-II ready) Parallel Universe is over.

Our Universe Prasanna - Congrats to Gotroch, deu and sinchai4547 who take the top 3 spots respectively. Also, congrats to Kishore (kishy72) for topping the Indian rankings with a well-planned performance. I was happy to see a good participation for this contest with 248 solvers in total. It was quite a wonderful experience authoring this one. Quad Max was the highest rated Sudoku, but its nice for me to see that 5 Sudokus (Linked Consecutive, Quad Max, 2 Even 2 Odd, Arrow Sequences, Palindrome Search) got a high rating. Even the classics, which I don't think I'm that good at writing in general, were well received. There were a few negatives of course, like points allocation being off for some solvers. But I feel there'll be an element of this in many contests, especially ones involving newer variants (like Hamle) because it comes down to the author taking factors into consideration like solvers being new to it, etc. It's not an exact process but obviously the intention is to have the points distribution as fair as possible. I think most of them were accurate, for which I thank my two great testers, Bram and Salih (and also for getting the testing done pretty fast as I was probably a bit on the late side with getting the set ready ).

In general I hope everyone enjoyed this contest, and I hope you enjoy the Puzzle version of it this coming weekend!


Their Universe Prasanna - Congrats to Gotroch, deu and sinchai4547 from your universe. I can't reveal the winners on this side because it'll break the time-space continuum. It was really fun translating the puzzles to my people and letting them enjoy the contest too. Obviously, we shall meet again, very soon, in Parallel Universe II! Check it out on the top right. I took a more active role this time in providing a list of types in our Universe for your Universe's Prasanna to pick from! I hope you enjoy the puzzle types from our side!

Nice puzzles - good for mid-level players like myself. Didn't get the parallel universe part but that didn't seem to be significant.

Anyone else have trouble with Linked Consecutive? I wasted a lot of time on it and came up with an ambiguity that I couldn't overcome.

Actually, one of my testers had this problem, and I had to show them the next step too, so yeah, it can be a bit difficult to spot. I assume the image they sent me covers the portion you're stuck with. In the bottom left grid, use coloring to prove that R1C1=R5C2=R2C3 and you should be able to finish things from there.

I don't know what "coloring" means. Perhaps this is the short-cut that I'm missing? Please explain.
I solved it both ways and had initially thought both worked tho' now I see the mistake in my "other" solution.

Coloring is basically a way to set placeholders meaning that certain cells will contain the same digit X. R1C1 is 3/6, so are R5C1 and R5C2. So if digit X is in R1C1, it'll be in R5C2 by eliminating itself from R5C1. This same digit will now eliminate itself from R1C5 (because its in R1C1) and R2C2 (because its in R5C2) and will therefore be in R2C3. Coloring's just a simple way of getting to this because you can color (or mark in some way like circling) the cells I mentioned instead of going 3/6 in your mind for each one.
