On Wednesday my son will tie the knot, so I wil be probably either too drunk or too tired to compete for the rest or the week.
Lots of luck to all players, and thanks to Riad for organizing this tournement, which will certainlay be fascinating as usual.
Stefano

Stefano, I sincerely congratulate and wish the newlyweds happiness!

Is there something wrong with the Optimizers column on the potential score page? I have submitted 2, but it says 3. For Christian, it says 4...

In task 7 are there two different sets of numbers for Battleship and Pentamino or are the numbers the same for letters in both problems?

Thanks for the answers... however, I haven't checked, but I thought it might be possible to form a polygon (possibly concave, which I suppose is permitted) by using the S clue twice and the NE clue once, for example, if the clues for a row are S and NE. If this were indeed possible, would it be allowed?

The numeric values of the letters are the same for both puzzles.

Concave polygon is allowed. It is also allowed to use a triangle (I received this question by mail). You can use the S twice and also NE if these clues are in the same row.

For the third optimizer (counting names), the words have to form a single connected component, isn't it? The rules don't mention it explicitly.

You need to get a single connect crossword in which each word intersects with at least one other. That's right.

For the second optimizer, Easy as Opti; do circles between the two grids have to conform to both grids, even if it is left empty? i.e. is a row allowed to have something like (1) --1234 ( ) 1234-- (3) where the (x) represents a circled cell? Or should something like this always hold: --abcX (y) --dXef where the relative of X is fixed even if there is no digit in circle y? I hope my question makes sense. So if both grids have to conform (the second case), a solver can use this information in the way we could use it in puzzle 6 Easy as First and Second in the sense that if an empty circle is deducted to contain digit X if it was not empty, then the other grid should also conform to that digit X being in the first or second position, right?

Cheers :)

The same as in puzzle 6. In the circle between the grids, the digit is common to both grids. If the circle between the grids is empty, you can find a digit from one grid and use it for the second.

Thanks for the answer to problem 10 (By compass). And for problem 12 (Counting names), if we can choose the value of a letter in certain cases (D which can be 10 or 19, for example) I suppose that the choice made for a certain letter in a certain place must be the same depending on whether we consider the letter horizontally or vertically, right?

Ah, I didn't understand we were taking those rules from puzzle 6. Good question Leonardo.
To clarify, is this statement correct Riad?:
"There must be a unique solution, which has a digit in every circle and both square grids filled according to the rules."

Thanks for the info! I updated my grid. In that case, for clarification one can think of placing the digits in the circles in the example solution, as they were also part of the solving process.

It is not necessary for each circle to have given digits. You need to create a puzzle with a unique solution within the rules of puzzle 6.

The translator gives a sentence that I cannot understand.
When you solved puzzle 6 letters appeared in the common circles that were correct for both grids. The same should be true here. When checking, I will write the digits only in the circles common to both grids. These digits should work for both grids.
To achieve a unique solution you can additionally enter numbers in the squares.

For the answer format for optimization problems, what exactly is meant by "Type one answer key per line"? Compared to the 'Answer format' examples in the booklet, you have to go to the line after each comma, right?

In puzzle 12 - Counting Names, are you allowed to submit an empty grid, or is it required to have at least one word in it?

You need to enter a word and cross it with at least one other word, so as not to break the rules.

Hello Riad,
I gave my answer for problem 12 (Counting names) before your answer saying it must be a single connect crossword. My answer has three non connected groups and in each group each word intersects at least one other word. Could you confirm that it is not a valid answer ?
Another question : If in a row or a column all the cells are blackened, this row or column has the score 0 in the corresponding oval. Is this right ?
