WCPN Author Posts: 191 Location: The Netherlands | rakesh_rai - 2012-06-24 3:38 PM OK. Somehow, I initially thought (wrongly) that the non consecutive constraint only applies on the gray bold lines. No problem. It's good that IB's appear and that forum threads are opened before a test is hold.  | ||

The numbers 1,4,7 in C7 and C9 in R2,R6 and R9 can be interchanged to form another valid solution. Plus, there are three more valid solutions (most probably). Exactly. The 4 is given in R9, so swapping digits is limited. The puzzle has definitely a unique solution. During solving this one, I had the feeling that it was not the first time I solved it. Just for my curiosity: is it an already published puzzle (perhaps from a previous year IB of DSM?), or have I dreamed it?  Fred | ||

Just for my curiosity: is it an already published puzzle (perhaps from a previous year IB of DSM?), or have I dreamed it? Fred Well, yes and no. The nonconsecutive ascending puzzles where among the hardest to make for this test, at least smoothly solving ones. So I wanted to use my older puzzle from the puzzle portal Germany first. (You solved it a few months ago.) This one. But it turned out to be a bit too hard, even for the IB. Since I liked the constellation of the puzzle very much, with the long line in the middle, I tried to reuse the idea and make an easier puzzle out of it. I think the one that is in the IB now is much more suitable than the earlier one would have been. So your feeling is correct and you are well awake! | ||

WCPN Author Posts: 191 Location: The Netherlands | Fred76 - 2012-06-25 12:13 AM Haha ! you really like this configuration ! Yep! I will be honest, it is one of my favorite configurations. I used it here for the first time. Only problem with it is that as soon as it is known by the puzzlers community, the power of it is gone. So it is definitely suitable for the IB, not for the real test. Consecutives are (next to irregulars) my favorite sudoku variant for a really loooong time, so this variant was the first one to put on my list for Copy Paste.

For the die hard fans of consecutives, here are a few more links: 1 2 3 4 5 But beware: most of these puzzles are too hard for a timed test! But they are fun to solve. | ||
