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 !

Hi Ronaldo,

Please try a easier windoku first and then come to this difficult. Try to understand the logic from the solution from the solutions as a last resort, as advised by the admin.

Hi again,

This is the first Equal Sum Lines Sudoku I have solved since starting to solve variants some 10 months ago. So I am not a expert and the experts have already given you hints. Still I will add one more. Please read this with the earlier posts with others.

The minimum sum must be 21 has been established. In box 9, since 1 can't be in R6C6 (minimum can't be reached, same logic to have put 2 in R1C2), we place 1 in R7C6, This means that 4 has to be in R6C6 or R6C7. So the maximum possible sum of the line in R6C6-9 can be 21 only (4+8+9). So we conclude that the Equal Sum is 21. With this deduction you must be able to solve, I suppose.

I am reluctant to post this because I am new to this and so I might have missed something. In some other variants after solving it in the Instructions I have found out that further insights are needed to solve the variant.

Keep trying and solve more of the same variants to understand it fully. You are bound to improve over time.

Beautiful set of puzzles. Loved x-sum, kid, and unique sums. Broke renban and got overwhelmed with rhombus during the test.

Thanks Rakesh!

That question on the feedback page can be ignored as mentioned earlier in the thread. Thanks Sedho!

Thanks Aashay! You started very well actually but hit a roadblock somewhere - either the killer or the slightly unfamiliar variants.

Thanks Kishore! Kid sudoku clues were kept simple with the only catch being that those rows/columns were blank. Otherwise, it was easy to deduce the different combinations to make 99999.

Thanks Harmeet! Unfortunate that you were not able to complete Renban and Rhombus within the contest duration.

Thanks Priyam! Glad you enjoyed the contest.

Loved the Little Killer and Kid sudokus. Thanks for a very nice contest!

Yeah, I broke the Killer 4 times, which ruined my contest, leaving me little time to attempt the unfamiliar variants, which I had left for the end.

Thanks to all 148 participants!

Congratulations to all winners, especially all participants who scored above 80. No surprises in the top 5 - Kota Morinishi, Seungjae Kwak, Hideaki Jo, Endo Ken and Michael Ley.

It was a challenging test - with some easy ones to start, some unfamiliar variants and some moderate to tough grids in the end. Also, special mention for Vijaya, Ritaban, Priyam, Aashay, Swaroop and Gaurav who were able to solve 10+ grids during the contest.

Rhombus and Equal Sum Lines were the least solved variants and Mini and Classic were obviously the most solved ones.

Hope you enjoyed the contest. And good luck to everyone for the upcoming WSC!

Great work Rakesh ! loved the variants .... ( did solve the IB ones at leisure) . Just wondering what the title was all about ? PENTAKAIDECA ( I must be missing something ! ) ?

Pentakaideca = "a fifteen sided polygon" - If you look at the contest image, it is a fifteen sided polygon, loosely representing fifteen sudokus in this contest.
