From the name, I'd guess something like: once you solve one grid, you need to copy and paste certain digits from that into another grid, and so on. But I'm just guessing- I hate it when they announce a test before the IB is ready, because I always hate the suspense!

Then you should hate LMI
(From experience of being an author) LMI announces a test 'after' IB is ready, the suspense is just to tickle some players like you

NO IDEA!!!

Infact i should have used the word Title instead of Theme.....very interesting title....
eagerly waiting for the IB....

I can confirm that the IB is indeed ready (actually it is for quite a while...) Nice to read that the 'suspense' works!

Just a couple of days patience guys!

I remember that last time I saw Richard, he told me about a next test he was preparing for LMI. But it was after 5 hours of sudoku playing and trying to speak in German and English all day...

So I don't remember what he said actually

I hope there will not be too many irregular sudokus

Fred

I welcome Irregulars now, bring it on :P But I'm sure thats got nothing to do with the theme/title.

Perhaps we need to paste the same answer key to all the puzzles

Wouldn't that be so cool?

Just like for my previous test ‘Shapes and Sizes’, I have gathered a few links to more practise material. The following puzzles appeared either in the puzzle portal of Logic Masters Germany or in a German Sudoku Championship.
If you have any question about one of these puzzles or regarding ‘Copy Paste’, please do not hesitate to ask; I’ll be happy to answer.

After completing the Copy-Paste test, I had a few unused puzzles. I have posted them in the puzzle portal of Logic Masters Germany yesterday. Here are the links to the leftovers:

Arrow
Sum 100
Ascending
Consecutive
Minimax
Maximin

With exception of the Arrow sudoku, all of the puzzles above are a bit harder then the ones of the same type in the real test.

Please look at my comment at the Arrow sudoku in the puzzle portal, explaining why I use a different lay out then the international standard. I hope my puzzle doesn't lead to too much confusion.

Does the ascending nonconsecutive grid in the IB have a unique solution?

Yes, and that is same the solution given at the end.

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).

In that case the 1 comes direct under the 2 in row 9, which is not allowed.

I'm not sure, but 4 can't be at R2C7, and neither at R9C7 because of the non-consecutive constraint.

Exactly. The 4 is given in R9, so swapping digits is limited.

The puzzle has definitely a unique solution.

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.

Copy Paste from here

It is easy to figure out that both SudoClones and Copy Paste have similar themes. It is interesting that Richard and Sylvain came up with similar ideas with few weeks apart (much before Clone round in BIST). Thats when we decided to schedule these 2 tests one week apart and to publish the IBs at the same time.

Luckily, the variations in these 2 tests are very different and I'm sure players will enjoy these tests like every other LMI tests.

Has anyone tried the consecutive from unused puzzles, not able to crack it

At a glance you can get the entire middle column using the fact that the upper part cannot be 4-3-2 and has to be 4-5-6. If you hadn't done that already, maybe that helps.

The upper right block provides very much information if you take a close look at it.

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

Haha ! you really like this configuration !
