There is a difference between OEVS and OEVSS. If you have in one row numbers "213..." the first visible odd skyscraper is 3, because 1 is covered by 2.

Ok. I get it. The example doesn't have any such case, so it was misleading. Thanks.


It did have a few examples I think, not exactly like the 213, but skyscraper logic was required. The "2" below R6C5 had to be satisfied in the first cell itself, since the 5 would block vision towards the 2. This is not the case in Even Odd View I guess, you could've had 5 in the first cell and 2 in the next with the "2" outside clue. (I'm saying this with memory of solving yesterday, so the placements may be a bit off, but the logic was there)

I have one question about B6 (Surplus-deficit sudoku).
Are there any restrictions for regions with exactly 8 cells?

We will update the instructions - "In regions with less than or equal to 8 cells, the numbers should not repeat."

In the competition, there will be no regions with 8 cells.
In the IB, you should aply both rules at once - in region with 6 cells no digits may repeat and each digit should appear at least once.

This test is all about Sudoku 8x8, so all the puzzles will have such size.

The theme of part B is ...without regularly placed regions... but most of the example puzzles are 'regular' 2x3 blocks. How do I have to see this?
Thanks in advance!

Best regards, Richard

It is just a IB. We were not able to construct 28 original 8x8 puzzles for Instruction booklet. We believe, that for understanding the rules/instructions it is enough to have smaller puzzles in IB. And also, it is not possible to rotate half of the rectangles in 6x6 puzzle as in 8x8 puzzle (see the classics A1-2 and B1-2 in the IB).

No problem!
I just wondered if more grids would have irregular shapes than the presented puzzles in B1-2, B4, B5, B6, B11 and B12.
I know how much work it is preparing a test plus IB. Having no less than 28 puzzles (x2) isn't making this easier!
I am looking forward to the test, since 14 puzzles for a bit over an hour seems like that there are a few quickies to be done, even for a midrange-solver like me.

Richard, you´re absolutely right. Some of the puzzles will be easier (it is not hard to discover which ones), so that is why we even haven´t tought about bigger (harder) puzzles in IB. And of course, we want to keep the best puzzles for the competition.
All the irregular puzzles (as Irregular sudoku, Surplus-deficit or Irregular without regions) are irregular in IB. Only the usual variants, which will have rotated regions, are unrotated in the IB.

Dear puzzle friends,
in Foursome sudoku (A11-14) there are four sudoku grids and the points may be distributed for each grid independently. However we accept only solution, that is valid for all four puzzle grids together!
This sentence is missing in the IB, but we believe, that it was clear also before.

Thank you for understanding!

I think there's a typo in B8: the 8 on the right edge should be 3+5+1 = 9.

Looks like this will be a fun test!

In X sum sudoku: the clue is on the right puzzle at column 4. The number 8 is wrong. 9 is correct?

An updated version of IB is now available with this typo fixed.

As mentioned earlier in this thread, the IB is just for illustration of the rules.

Announcements - No Online Solving

LMI flash interface does not support Cube Sudoku. Also, it is very difficult to solve Irregular W/O borders on the flash.
So, it is decided that online solving will not be available in this test.

I really need to learn how to use the printer :| Also probably not a good idea to give the test tonight, still need to work on my patience.
Anyway, some really nice puzzles, will need to get back to all the ones I solved wrong. :P

Wow, lots of fun puzzles, thanks!

I'm pleased that I turned one in with about 30 seconds left on the clock in part B. I hope I got it right.

One small correction, perhaps: It seemed like several times the input instructions said "row" when they meant "column" based on what was drawn on the paper.

Now it seems like about half the time when I reload, it comes up blank, and the other half it gives me all the information as usual. (Of course, I only get to test once per hour or so.)

Checking what could be the problem.
As admin, I can always see the results. So didn't realize that there is a problem.

I also didn't see the results page after I completed the test - table was blank. So I've no idea how many puzzles I solved correctly, and how many not. Well, I can see the results in 22-nd of May when I come back from China. Until then the excitement stays...
Puzzles were nice, except I didn't like pencilmarks so much. Probably, because I spent so much time on it:)
