Very nice set.
For the 6x6 No Even Neighbours, I directly filled the 5 remaining cells of the answer key (3rd row) without putting any other digit :-)
Thanks for your feedback. Will be more careful next time in selecting answer keys. |

The main problem was the answer keys, because there were few sudokus where I filled less than half cells. It's perfect competition for the beginners, although I found the last puzzle very very uncomfortable to solve (quite hard). So, it matches the idea about not to put too hard puzzles there, just you need to use a bit more narrow solving paths or just work more with where to putt the andwer keys.
Thanks for your feedback. I hope you enjoyed the test overall.
Can you specify the Sudokus where you filled less than half cells ? . I hope they were all 6*6 size sudokus where this was possible. I like your idea of having bit more narrow solving paths, which will reduce this issue to some extent in such small grids. The challenge was, we are experimenting to have just 1 answer key for 6*6 size sudokus instead of 2 answer keys which we usually have. So I believe it is difficult to find just 1 row or 1 column which will be filled last in 6*6 size grids. But definitely we can improve the choice at least in some of them, for e.g. No Even Neighbor 6*6 as pointed by Rohan. Will try our best to improve upon that in upcoming tests.
Once again thanks for your suggestions. |

A fun and excellent test!The pattern of digits and the theme in almost all the sudokus were really nice.
I greatly enjoyed solving No Even neighbours(12) which forced me to use some marking for odd/Even that I usually forget in sudokus.
The Odd Even Count was exciting too .I enjoyed spotting the triplet (3-4-5)in the middle Box.In addition,I remember doing something with the 6 which was really good too.Of the Classics, the 1-9 theme and O and E theme stood out.I never really thought about points as I completed all sudokus until the last digit was put even though the answer keys came earlier.Had my own share of problems in the form of catridge drying out and me replacing it in the middle of the test,printing the alignment page (which I was forced to do)but they never diminished my experience of the test in any way.
Regards share of creation,I can almost say which were created by whom :)

Thanks for the test!Good work.

Location: India | In odd even count 6*6, I had put incorrect answer keys. But when I tried to correct it, the previous incorrect keys couldn't be deleted. Why ? |

Location: Switzerland | Thanks for the tournament !
Nice sudokus ! Appropriate level of difficulty for intermediate players I think.
It was nice to restart playing sudoku after WSC with this test.
About the answer keys and the choice of rows/columns: I didn't care that much about codes on this tournament, perhaps because since WSC I'm used to fill all cells in each sudoku I solve.
However I also noticed here and there that the choices of rows/columns for answer keys were not always optimal.
On a few 9*9 sudokus, the 2 rows/columns choosen covered only 3 regions (for example on 9*9 No Even Neighbours). While it can be a good choice for some sudokus, you have to be sure that these 3 regions are really the end of solving path of this sudoku. It's always a risky choice. On the 9*9 No even neighbours I found that it was not optimal. |
