Serbian Puzzle Championship

This test will also be used as Serbian Puzzle Championship. So this test will start at a time which is most convenient to Serbian participants, i.e. at 22:00 hours Serbian time on Friday. Submissions until 00:40 hours (next day) Serbian time will be considered for the championship. So Serbian players must start early enough to permit themselves full solving time.

The given ships in Sea Battle are wrong. In the solution, there are three 3-cell ships, I think one is missing in the given :)

Thanks so much. We had few new players from China in the last Sudoku test. Lets hope that repeats this time.
By the way, I find your new method of translation much interesting. I reckon it is easier than the previous method of copying all images.

In the Sea Battle you have to recognize that there are 22 ship elements. And there are 11 regions. Hence all regions contain exactly 2 ship elements from 2 different ship.
(I think there are just some places where the 4-long ship can be.)

Acorrding to sum, like 31 in r4c3, we can figure out r56789c3 must have digits.
4 in r8c4 shows r8c68 contain 1 and 3, because of the rule "empty cells cannot be adjacent".

Then

In Col 9, the sum is 10, so only two more cells can have digits.

r79c8 must contain digits.

r7c7?4, r7c8?5, so r7c6 must be blank.

if r8c8=1, then r7c8?8 r7c8+r7c7?12, so r8c8=3, r8c6=1.

In r9c78 only one can be 9, so r7c7=45, r7c8=56,
then r7c9=1->r7c7=4, r7c8=6...

Same logic is applicable to 11 in Column6

Only if there is some blank between rule and puzzle image for typing, I can do like this

Do you know the software "HyperSnap"? It's easy to snapshot picture and edit it.

See the picture before it.

Remember the rule "empty cells cannot be adjacent", and Col 9 only can have two digits more.

Maybe this question was answered somewhere before, but I am too lazy to look for it now. In Number Skeleton puzzle does it matter in which direction are the numbers fill in? The IB has also another solution, when you turn it (199, 2X8, 357).
Thanks

Have the solutions to the practice test been vetted? I believe I found multiple solutions for the Sea Battle. And I found 2 solutions for Liar Slitherlink [the cave end in the lower right that surrounds the 1 in R6C5, could also be shortened to only go around R6C4 and still be valid]. Just checking.

All the puzzles from IB have only one valid solution. In the Liar Slitherlink you probably forget to use columns, where is also only one incorrect clue.

The row/column marking is incorrect here. First row and first column should have been marked. The answer key, in that case, is 199#123 or 123#199.
