Good puzzles, but really not a huge fan of 6x6 puzzles that are actually non-trivial.
I feel the best strategy is to trial-and-error through them since they are hardly worth any points rather than logically working them out (which takes longer).
When I look at the 6x6 XV or the 6x6 Consecutive, I am not convinced that these are great introductions for solvers before they tackle the larger 9x9.
I think the reason they are worth a lot less is because they are more prone to lucky guessers.
I suggest either: A/ having it worth more, since the steps are non-straightforward or
B/ have the 6x6 actually be simpler since they are worth way less points.
This is an interesting point to discuss.
So first of all, at least for this contest, the test solvers have solved the 6x6s and 9x9s logically. So guesswork did not factor into the timings, and the points were calculated and assigned based on the timings and not any external factors. So in that sense, I'd say at least in theory that they weren't intentionally undervalued or given a lower value 'because' of a quicker solving path via guesswork. So I don't think A can be done here since it would just be random subjective overvaluing.
But about them not being great introductions, I would love to discuss further because I see it going both ways. I think that if there is an introduction, an intermediate and then a final level, then what you say is definitely the way to go because then we can have the intermediate preparing solvers to tackle the regular difficulties while the introduction can be easy to be most approachable. But since we just have a 6x6 directly leading into a 9x9, a straightforward 6x6 leading into a difficult 9x9 doesn't do much in preparing you for it. So personally I think it is fine to have some easy ones and some difficult ones among the 6x6 variants within the format used here, to give options both of approachable variants and of variants where, if you attempt the 6x6 logically, you'll be better equipped to deal with higher levels and difficulties. |

Hi. The Instruction Booklet will have a Linked Sudoku example with its solution. The corresponding shaded cells in both sudokus will contain the same digits. So, if you get any digit in a shaded cell in one of the sudoku, then you can directly fill up the same digit in the other sudoku in the corresponding shaded cell. |
