Since it coincides with TVC XIX, this will start a day earlier (i.e. on 12th) than usual SM episodes.

Can the duration of the test be added to the IB?
I'm sure most of us know the timings and duration, but it was pointed out last time and there's a chance a newcomer 'might' miss it too.

Just to clarify . Please correct me if I am wrong.
In QuadMax 4Odd 4Even Sudoku ,the arrows provide 2 kinds of information.
i)All 4 cells comprised by a single arrow are of the same parity .
ii)The arrows point towards the cell with the highest digit.In case there are 2 digits with the highest value,they will be represented by arrows with double heads.

Also ,apart from the above,I remember seeing Average in an earlier SM round (not this year) and finding it unpleasantly sticky.Can someone direct me straight to that round? I think that round was authored by Rohan or Rakesh ?!

In kropki, if no dots are there can it be supposed that neither the difference is 1 nor one one digit is half of other ?

And one question more, can someone give me few starting clues as to how to solve average 6*6 and average 9*9 in IB because I am confused from where to start

For 6x6, look at 3rd row. There will be 1 at R3c6 and 6 at r4c1. This should give you start. Remember Extreme numbers can never be on the cell with average symbol. i.e. 1,6 for this example and 1,9 for 9x9 grid.
I am posting one more post with practice links and tips. That will help you to get started.

In addition to Swaroop's post of assembled links and tips, I thought I'd share the only site where I have prominently seen Quad Max 4 Even 4 Odd - http://www.argio-logic.net/ . If I remember right (I have been auto-logged in for years now), registration is done by clicking on the forum link. Once registered, clicking on the 'Sudoku' link near the top left of the home page link I shared should give a list of Sudoku variants where Quad Max 4 Even 4 Odd will be there.

We will add to the IB in the next version when we also add the points table.

Precisely! There are three possible cases - (a) No arrows: The 4 cells do not all have the same parity, (b) One sided arrow: All 4 cells have same parity and the cell where arrow points has the highest value. (c) Two sided arrow: All 4 cells have same parity and both cells where the arrow points have the highest value.

It is an interesting twist that the number of points that the X-sums frame sudoku is worth must be figured out during solving!

For those who missed the Sudoku GP Round-2 last weekend, it might be useful to try out some of the variants. Though, not explicitly mentioned, many of them turned out to be 'Converse'-like variants. Good practise before the Converse round in SM.

A partcipant asked this question. Sharing it here as it may be relevant for all.

i hv a question regarding x sum frame in converse variations sudoku instruction booklet
in the 6X6 grid m getting left with numbers 4 and 3 left in the second column of the first grid and same numbers in the parallel grid in 5th column.
can you tell me where m getting it wrong.

Since there is no X to the left of the first row, by converse rule, the sum of the first three numbers cannot be equal to X. (X=7 here) If row 1 column 2 has a 4 the sum of first three numbers in row 1 becomes 7. So this cell must contain 3.

Anybody give some clues on kropki sudoku 9*9 from IB. I want to know how to start as there are very few clues and I don't know where to start.

And also please give some starting clues for x sum frame 9*9 from IB.

Anybody give some clues on kropki sudoku 9*9 from IB. I want to know how to start as there are very few clues and I don't know where to start.

Look at column 4. Because of the 2s in col5 and col6, a 2 must come in C4R1 or C4R2 -> this means C4R1 and C4R2 must have the numbers 2 and 3. Then C4R4 has possible options as 5,6,7. 5 and 7 are not possible because of converse rule. So it must have the number 6. C4R6 now has possible options 5 or 7. If it is 7 then C4R8 and C4R9 will be 4 and 5, which is not possible. So C4R6 must be 5. Now C4R9 must be 4 as we have a black circle. And C4R7 is 7.

In general, try to start around black circles, as they are the most likely places to start. Then try to look for long consecutive sequences in a row/column/box. If you are stuck or there is less progress initially, some amount of pencilmarking around the marked circles can help get the breakthrough. After that make sure you do not forget classic rules AND converse rules. For example, if a cell has 3 and there are no circles then the neighbours cannot be 2,4, or 6.

I hope you will be able to solve this one now.

IB X sum frame 9x9: C4R4 = 4 (singlet). Concentrate on C5... C5R4 and C5R6 must contain (2,6). So, R5C4 and R5C6 must contain (3,8). Also observe that, C3R4 = C7R6 = 8.

Can you explain how you got (2,6) and (3,8) ?

>>>And also please give some starting clues for x sum frame 9*9 from IB.

The starting approach has to be to find the possibilities for X, without forgetting classic rules.

For example, in the IB, if we look at column 6, the first three numbers can have three numbers from 3,5,8 and 9. So the possible values of X are 16, 17, 20 or 22.

Now look at row 6. The possible values for first three numbers are 2,6,7,8 and 9. Using these numbers, we cannot make 20. So X cannot be 20. Also, if X=16, then we need to have 2,6 and 8 as first three numbers. Then we cannot place any number in R6C5. So X cannot be 16 either.

The possible values for X are now 17 or 22.

Similarly, you can deduct that X cannot be 17 as it leads to a contradiction in Boxes 4/5/6.

Once X is identified as 22, there are only two ways to make 22 (589 or 679). You will be able to solve easily after that.

In column C5, the middle 3 numbers (in r4,r5,r6) must add up to 12. Two numbers are 4 and 2, so 3rd one must be 6.
Why the middle numbers add to 12? Because in C5, 1st 3 numbers (r1,r2,r3) = (45 - X - 12), and last 3 numbers (r7,r8,r9) = X. So middle 3 numbers = (45 - (45 - X - 12) - X) = 12.

Really nice sudokus!
I was lost on both the Average sudokus... but otherwise it went smooth.
QuadMax 9x9 and X-Frame 9x9 were my favourites.

Thanks Harmeet and Rakesh.

Thanks for another great test Rakesh and Harmeet. All of the puzzles I solved were very nice, but my favorites were QuadMax 2 and X Sum Frame 2 (I really liked the deductions for X in this one).

Really nice sudokus....Liked construction of all of them.
Hats off, Rakesh and Harmeet.
Kropki seems to be a no starter for me logically, Rakesh/Harmeet, please provide me THE logical starting point.

Technically for me 2015-16 SM is ended as, I will be co-authoring last round of SM along with Amit.
All the rounds were really great and I enjoyed them a lot. Thanks for the authors and organizers for all great SM rounds throughout the year.

I guess you are referring to the 9x9.
(1) One starting point is R1C3/C4 -> one of them has to be 3. You can find out easily that the 3 must go in R1C4. You can then fill out all cells in row 1. R1C1 cannot be 5 (look at the long sequence in col 1) so it will be 1.
(2) R5C1 is even (count odd/even in box4). Using this, we can complete col 1, as there is only one place for the number 2.

After this, it should be simpler.

The puzzles were all right but the point distribution was rather poor. IMHO for the big kropki 16 points were faaaaaar too many, while the big average with only 13 points was underrated.

Thanks a lot Rakesh, I really forgot to use Even/Odd marking , it makes it so easy which was looking a non starter to me , I remember Prasanna also mentioned it earlier.

That is right. We would have extended the time only if we are requested before it is over.

Congratulations to jzverina, deu and jaku111 for securing the Top 3 positions. In fact, 4th to 10th positions were very close, with only 6 points separating them. Thanks to everyone who provided a feedback on the test. Glad to see the two relatively newer variations - X Sum Frame and QuadMax 4Odd 4Even - getting the bulk of the votes. Congratulations to Rohan, PRasanna, SuvaRna and ShaheeR for taking the top places for India. Also good performances from Amit, ManjiRi, KishoRe and NeeRaj. Thanks to Rishi for test solving this set.

Overall 315 users, and about 10% of participants (33) completed all 18. Average 6x6 had a lot of erroneous submissions (1 out of 3 wrong) as participants tended to guess since it was a 6x6. However, there is a neat logical path to solve it. Kropki 9x9 was the least attempted with only 93 correct submissions. However, I had expected QuadMax 9x9 or Average 9x9 would be the one with least submissions as the come last in the PB.

We have puzzle wise submission data for 6 of the top 10. Based on their timings, Classics should have had 22 points (we had 22), Consecutive should have 15 points (we had 13), Kropki should have had 18 points (we had 19), X sum frame should have had 13 points (we had 12), QuadMax 4Odd 4Even should have had 15 points (we had 18) and Average should have 17 points (we had 16). So, except for QuadMax 4Odd 4Even, the differences were less than 3.

HaRmeet: You may also share your impressions from this test.

Thanks to LMI for hosting the test and especially to Rakesh for guiding throughout. Together we came up with the set, the standard ones were kept reasonably simple to compensate for moderate to difficult variants. I hope all of you have enjoyed solving the sudokus. Congratulations to the winners! It was awesome to see 30 participants solving all 18 within time. The feedback is yet to be analyzed. This was my first attempt as an author and I have learnt a lot from the experience of creating them. My personal favorite was Average 9x9.

So, except for QuadMax 4Odd 4Even, the differences were less than 3.

Interesting. It might also be worth comparing on grid-size rather than variant.

I was one of the players who voted negative on the points distribution. It might be a personal experience, but I struggled on the Average 6x6 (spent 11 minutes), compared to the Kropki 6x6 or X-Sum 6x6, all of which were of equal points. I also found the Average 9x9 (13 points) much harder than Kropki 9x9 or QuadMax 9x9 (both 16 points).
Maybe I am just bad at Average :-(

Huh, I had just the opposite experience: I flew through the Big Average (probably took me less time than the small Average) but couldn't find any opening for the Big Kropki.

Thanks to the puzzle makers!!

Does anyone have general tips for kropkis (and kropki sudokus)? I always have a really hard time starting them, and I often just end up having to use trial and error until I find something that works.
