Posts: 739 ![]() ![]() ![]() ![]() Country : India | vopani posted @ 2018-03-09 1:05 PM Why these Sudokus were rejected for WSCVariant: Alphabet Sudoku Round: Welcome Author: Prasanna Seshadri Reason: This was initially to be the first sudoku of WSC. But when we decided to theme the first round with 1 Classic and 1 Variant, we decided to drop this since it is just a Classic in its raw form. Variant: Classic Sudoku Round: Welcome Author: Rajesh Kumar Reason: The theme was too similar to the 'Hash'-themed Classic in WSC, which had a better solving path. Variant: Group Sum Sudoku Round: The Duets Author: Prasanna Seshadri Reason: Math variants contributed to a higher proportion of total points, so we replaced this with a much easier non-Math variant to balance it out. Variant: Group Product Sudoku Round: The Duets Author: Rohan Rao Reason: Math variants contributed to a higher proportion of total points, so we replaced this with a much easier non-Math variant to balance it out. Variant: Trio Sum Frame Sudoku Round: Two To Tango Author: Rohan Rao Reason: We chose not to include any variant with outside clues in this round. Variant: Classic Sudoku Round: The Originals Author: Ashish Kumar Reason: We had two equally good Odd-Even themed Classics for this round, and picked the one which was created first for WSC. Variant: Symmetric Dots Sudoku Round: Think Different Author: Rohan Rao Reason: There were a lot of ideas and sudokus for this round, and this didn't make the cut. Variant: Hamle Sudoku Round: Is It A Sudoku? Author: Prasanna Seshadri Reason: The variant was too puzzlish in nature and the theme seemed a bit too cool even for a WSC. Variant: Instructionless Sudoku Round: What Is It? Author: Prasanna Seshadri Reason: We decided to avoid any non-9x9 variants for this round. Variant: Killer Joker Sudoku Round: The Joker Author: Prasanna Seshadri Reason: We felt the rule of the Joker digit assuming a digit already present in a cage a bit ambiguous with regard to Killer rules in this round. Incidentally, this was the sudoku that actually ignited the idea of this round. Variant: Touchy Sudoku Round: The Usual Suspects Author: Rajesh Kumar Reason: We could pick only 12 variants for this round, and this one had the least interesting theme. Variant: Just That Cell Sudoku (Extra Region) Round: Do Not Blink Author: Deb Mohanty Reason: We reduced the number of sudokus in this round, and this one didn't have a particularly good appeal. | ||||||||||||||||||

So many mathsy sudokus! I suck at math. Was so happy to solve the instructionless sudoku in the last minute, but it doesn't show up on the score page. :-( | ||||||||||||||||||

Posts: 1 Country : Denmark | CSteinhardt posted @ 2018-03-10 1:58 AM I also submitted a correct answer in the last 5 minutes, for 9 (first try) and for 12 (not first try). However, neither is reflected in the final score, even though the online form marked both as correct. Did I do something wrong in submission? | ||||||||||||||||||

I don't like math variants in usual. So apart from leaving that, i was able to solve most of it. Definitely hard set of puzzles. But nonetheless excellent quality and wonderful puzzles. | ||||||||||||||||||

In some cases I got the idea why they were not included in WSC. Few of them were quite tricky to solve and rather required some other skills than sudoku. Few of them on the other hand were really nice and such a pity they didn't appear in WSC. But this is the idea of having this competition. Still a chance to try them. And generally all the puzzles were interesting. -Personal favourite was instructionless. Wonderful idea. But I kind of understand the reason why it wasnt included. -What I don't understand is why extra region wasn't included. It's 10 times better puzzle than this coded sudoku which was ridiculous just to see by looking it. ER was perfect to see the solution in 1 minute. -Hamle would have been a better sudoku than battleship. But that is just my opinion. The idea of having digits in second grid is a good idea because it turns it closer to sudoku. -Group sum and product included a bit more serious math than it would be appropriate. Good to see them here. Also just my thoughts. In some way trio frame felt also a bit frustrating but maybe I just don't feel well with these math puzzles. Joker would have fit well also in wsc same weay as clock faces or battenburg. I actually liked the killer more and at the same time I liked it less. It was one controversial round for me then. -In symmetry dots it was difficult to get the rules at first. I think I got the rules after 4-th reading. But I have never said that I am very good at english. -Touchy was tricky and challenging, but very nicely and logically solvable. | ||||||||||||||||||

Posts: 152 ![]() ![]() ![]() Country : United Kingdom | detuned posted @ 2018-03-13 2:39 AM Whilst I feel the concept of "is it a sudoku" is a little too experimental for a world championship, I find its exclusion because it was too puzzle-ish to be a little strange. If you were erring on the side of caution here, the best thing would have been to can the entire round - but given that didn't happen I felt that the Hamle clues resolved very quickly using simple sudoku-like logic scanning rows and columns, and would have been perfect for the concept of the round. I imagine its evil "logidoku" twin could also have been made sufficiently awful to solve too! Can't say I much enjoyed the Touchy puzzle (these are in general not particularly fun to solve), so I'm glad that didn't make the cut. The instructionless also looks pretty tricky, but I haven't yet started to solve it. | ||||||||||||||||||
