Posts: 13 Location: USA | For Kid Sudoku, is it allowed for consecutive digits in external sums to overlap? That is to say, could "3412..." be represented by 78573... or something similar? Also, are all cells in rows/columns with given sums included in at least one sum? So that 341 could NOT be represented by 31...? For Renban Sudoku, does the "distinct consecutive" refer to within each shaded group (so no repeating in a shaded area) or to each group in the puzzle (so no two shaded regions can contain the same combination of digits) or both? These are ambiguous to me from the instructions and the solutions, and I can see them having an impact on the solving. Thank you! | ||||||||||||

Within each shaded area no numbers can repeat. But the numbers must form a set of consecutive numbers. 2. It is possible for two (or more) shaded regions to have the same combination of digits. | ||||||||||||

So that 341 could NOT be represented by 31...? 1. No overlap is allowed. So 341256789 will be represented as 876789. We keep on adding numbers till the sum is less than or equal to 9. There is only one way to represent any row/column. 2. All cells are included if a clue is given. The sum of the numbers in an external clue willl always be 45. Some examples: 829356471 will be represented as 82986471 356271894 will be represented as 888894 192837465 will be represented as 192837465 And so on | ||||||||||||

Also, you can refer to the attached image (from sudokuwiki.org) for hints. All cells of the same colour must contain digits 1-9 exactly once. | ||||||||||||

Posts: 14 Location: India | Hi Ronaldo, Let me try to help you. You rightly found that 1's spot to be R6C9. The next number I placed was 7 in R8C7, by this sequence of eliminations: Because of 7 in R3C1 & R5C9, 7 can be only in one of R6C2 or R6C3. So 7 can be only in one of R9C2 or R9C3.(R6C2 and R6C3 are part of the same window so other cells in that window can not have 7). Because 7 is either in R9C2 or R9C3 and there is a 7 in R5C9, so we can place a 7 in R8C7 for that box. The next number I placed was 7 in R7C5, now find the logic behind it and you are on your way to solving this. It took me much longer than usual to solve this sudoku, so I think the level of difficulty is rather very high. So do not sweat it, if you can not solve this. Try the web for some easy Windoku puzzle and you will be able to solve I suppose. Again this is only the Instruction sample and it indicates that in the test this puzzle carries only 2 points, so I expect this puzzle to be very easy in the test. Best of luck | ||||||||||||

Mean Minis (2020) Author Posts: 749 Location: India | Ronaldo - 2019-09-18 9:25 AM Try to find out what the "equal sum" could be. What could be the minimum possible value on the slanting line. Also try to look at other lines and eliminate possibilities. Also, you can fill some cells by classic rules.Hey can u help me with equal sum line sudoku also¿I am also not able to fill that also | ||||||||||||

Posts: 9 Location: India | Hi I can try helping you. Look at the long slanting line and calculate the minimum sum. There is a 5 in box 3. The minimum in box 5 will be 1,2,3 which is 6. The minimum in box 7 will be 1,4,5 which equals 10. so the minimum possible sum in a line is 5+6+10 =21. Now look at box 1. 2 can come only in R1C2.or R1C3. If 2 is in R1C3, you will need a minimum of 19 in the 2 cells below (R2C3 and R3C3) which is not possible. So 2 can fit only in R1C2. You can try the rest after this.

Feedback page asks for 3 favorite puzzles, but the choices are about whether the puzzles were worth the right amount, so I'll answer here instead: 3 favorite puzzles: Little Killer, X-Sums, Odd-Even Bridge | ||||||||||||

Thanks Rakesh for a refreshing set of Sudokus. Really enjoyed solving them. I was a bit patchy and messed up Killer multiple times, but the overall quality of Sudokus was quite good. | ||||||||||||

Great set of sudokus Rakesh ! I thoroughly enjoyed the contest and it was hard to choose a favourite amongst these.However, if I were to pick a few, LK, X-Sums and Equal sum Lines would top the list in that order. The sudokus were very nicely constructed and were clean as a whistle.I was mostly concerned about Kid sudoku as I haven't seen this type much before in the past.Fortunately, I got through that rather fast after getting the idea.I had major hiccups in Rhombus and Diagonal towards the end but thankfully I didn't break those. Thanks a lot for the contest ! | ||||||||||||
