My intended break-in for Akasuke was that 2003 can only be placed in either of the two right vertical rows. Then 0103 and 1103 needs to be placed in 2 of 3 possible horizontal rows (not the two columns where 2003 could fit since that would make it impossible to fill in 2003) - and there would only be one possible combination to fit the two hanging 3s. From there, the next leap is looking at 0200, 0201 and 0202. At which point the grid would have 2 of 3 places where there's a 020X pre-determined. Afterwards, using simple Akari rules, everything should fall neatly.

After solving the centre, the Nansuke's focus was that all 5-digit numbers start with 5,7 or 9. Also to be noted is that all 5-digit numbers starting with 7 has 8 as their third digit. Knowing this, simple logic is enough to finish Nansuke.

With the Searchdoku, after solving the Wordsearch part of the puzzle, you will notice BADMINTON is missing and since the sudoku grid is surrounded by E's, the BADMINTON (with two Ns) must be placed diagonally. Using crossings from the Wordsearch (especially TEAMMATE), the puzzle simply becomes a sudoku.

The 6 highest rated puzzles were all from the fused types, which is great news to me, because that means the fusion was enjoyed by the solvers.
Thank you once again.

I think the first part of this description is slightly wrong, at least from my solving experience. The either/or on 2003 was also my first step, but then I can't follow up as you say to place the other entries with 3's. There aren't three posssible horizontal rows to take the 0103 and 1103, just two with the second digit 1 impossible in two of the four horizontal choices that can take a trailing 3, and you can't put both of them in these horizontal rows as they share too many squares. Instead the second of 0103/1103 has to be in one of three VERTICAL spots on the left of the grid or in the middle of the grid. I don't think you can even say that one of them has to be horizontal, to be honest, as there are valid arrangements that use the top-left vertical, the middle vertical, and one of the two far right vertical, for all of 0103/1103/2003, only failing when you pack in the rest.

I didn't find any trivial logic to eliminate all these possible placements of either/or pairs, but I did think the easiest situation to experiment with to eliminate one spot was the top-left most vertical entry, which with a horizontal option forces itself to be a 1103 as it only leaves a spot for a 0103 going in just one place. Fortunately for me, this ended up being the correct situation to get to an answer. I've struggled in looking back at it since to prove it is the only one, but satisfying the 2's is indeed the most challenging part. I just don't see what the "next leap" is actually meant to be with them, unless there actually is a good way to get the 1103 and 0103 down as I guessed them to be.

In other words, I think I got a little lucky, and this puzzle probably is the hardest of the set as there is no trivial first deduction.

In terms of issues such as the legibility of text, both for entering solution keys and also the tiny kakuro clues (which I too couldn't read that clearly once printed, even though I used a laser printer), now that there are so many excellent puzzle competitions on LMI might it not be possible to summarise for authors what text sizes and shades of grey "work" and which don't? Also important are page sizes and margins - this test had huge white margins which were unnecessary and made things smaller than they needed to be, and I've also noticed page sizes varying between authors (perhaps Letter versus A4, but I haven't checked to see).

Maybe, when a page is printed without any scaling, there could be a suggested minimum size of clue text and maybe even a minimum size of cell for sudoku-esque puzzles? And page sizes could be chosen so that they are scaled equally when printed on both A4 and Letter? (i.e. pick the minimum of the two sizes in each dimension so that whether you print 'to fit' or 'at original size' you will get a test that prints at a consistent size and is not cropped). In that way tests would generally print with content at the same size no matter where in the world the solver is. It's easy to do this if you're aware of it but possibly something that puzzle authors don't always think about.

Can someone tell me how to solve akasuke?
I only find two "0" by "2003" :(

Tawan and Thomas have given some hints a couple of posts earlier.

I had to miss this test, and I'd like to download the booklet. Unfortunately, the [url=http://logicmastersindia.com/lmitests/?test=M201111P]test page[/url] links to the PDF that is still password protected, and the password is not listed on the test page. Could somebody post the password?

Forgot to remove the password after the test. It is removed now.

In any case the password is TantAluM_tungsten and Tawan never told me what it means

A bit weird, but on the periodic table I once deleted Re (Rhenium) an substituted it for An (some random element), leaving Ta (Tantalum), W (Tungsten) and An which spelt out my name and bragged to my friends about how the table contained my name. The capitalized T A M is merely my nickname. :)
