    Hi Jan,
    Thank you for preparing IB in English! Here are some questions and comments:


    LITS: In page 3 the title is “5+6) LITS”, but on the list in page 2 it’s “5) LITS”. How many puzzles in the actual test?
    JAPANESE CORAL SUMS: In Czech version there is a sentence “Součty jsou uvedené ve správném pořadí.” which means “Sums are listed in the correct order”, but not such a sentence in English version.
    SIZE MATTERS: In Czech version there is a sentence “Některá černá políčka jsou již vyznačena, vyznačte všechna ostatní.” which means “Some cells are already shaded”, but not such a sentence in English version.


    LIAR SLITHERLINK: The first sentence says “Draw a single, non-intersecting loop that only consists of horizontal and vertical segments between the dots”, but there must be diagonal segments as the last sentence states.
    PERSISTENCE OF MEMORY: The example has multiple solutions. (in 2*3 rectangles, the loop can pass the middle two cells vertically)


    List: In Czech version “Diagonální cihly” is only No.11 and there is Kakuro in No.27, but in English version there are two “Diagonal Bricks” in No.11 and No.12, instead of Kakuro.
    DOMINO SKYSCRAPERS: In the example, the right-side clue in the 2nd row should be 2, but it leads multiple solutions.
    TRIPLE DOUBLE BLOCK: In the example, the 4th-column clue on the left grid should be 2. In the 3rd and 4th rows in the middle grid, 2 and 3 can be swapped.
    DIFFERENT VIEWS: The example has multiple solutions. (in the 1st, 2nd and 7th row, Some digits can be placed in other cells)


    Overall: In Czech version, the contents of round 4 and round 5 are switched.
    NEIGHBOURS: Do neighouring regions share only one edge-segment? (If they can share more than one segment, the example has multiple solutions)
    COUNTRIES: In the example, the bottom clue in the 1st column should be 3.
    FILLOMINO: The example has multiple solutions. (the shape of right 5-cell region can be slightly changed)


    Overall: In Czech version, the contents of round 4 and round 5 are switched.
    EASY AS ABC: In the example, the right-side clue in the 4th row should be B.
    INNER EASY AS ABCD: In Czech version there is a phrase “(v druhé tabulce A, B, C, D)” which means “A, B, C, D in the second puzzle”, but not such a phrase in English version.
    ABC BOX: The example has multiple solutions. (some letters can be changed in the 4th row)
    DOMINO: The example has multiple solutions.
    STARBATTLE: There is a hyphen in the example, which isn’t mentioned in the rule. Can cells with hyphen contain a star?
    DIAGONAL HALFDOMINOES: In the example. the clue “5” should be 4.

    Thank you for reading!

    12. TWO STEP MAZE
    like in round 7, are bold segments (mean that the way should not pass through them) given in the grid?
    If so, is it true that all such segments in the grid are not the borders of puzzles but the clues of Two Step Maze?

    13. YAJILIN
    Suppose there is no statement that the grid must be rectangle, is it allowed to arrange shaded cell(s) like the attached image?

    17. CAPSULES
    The following rule seems to be missing:
    No letter (number) is repeated in any outlined area.

    Is the size of all outlined areas the same and equal to the number of given letters?

    16. FENCES SWITCH
    Like example, is a blank grid printed next to the actual puzzle?
    If so, should the digits after switching be also written in?

    6. MATCHING PAIRS
    My teammates would like to know the definition of “vertices” in this puzzle.
    (For example, is it allowed that more than two vertices are placed on single line?)

    4. PENTOMINO 2 in 1
    Are 12 pentominoes given for each grid (24 pentominoes in total), or allocated into 2 grids (12 pentominoes in total)?
    If the latter is correct (12 pentominoes in total), does each grid contain exactly 6 pentominoes?

    Quick confirmation – is it mandatory to shade unpassed cells?

    Yuhei, this is exactly an example of a puzzle that needs clarification. We want to avoid any inconsistencies when marking the puzzles.
    Yes, the rules will be published in a written form and no, it won’t be on the competition days. I think it is fair to publish it online before the Q&A session if further clarifications are needed. Is that OK?

    Thank you so much!
    If there is further confirmation regarding answering needed, I will post it on appropriate thread of each round.

    3. – 4. FULL CAVE
    I think there is a typo in the following rule;
    All shaded cells must be connected to the edge of the grid through other orthogonally adjacent unshaded cells.
    should be
    All shaded cells must be connected to the edge of the grid through other orthogonally adjacent shaded cells.

    Hi again,

    I’m sorry for bothering you so many times; here are additional questions which came up with from our team members.
    1) Search 9 Sudoku: if there is an arrow pointing a diagonal direction, the number placed in this cell indicates the position of “first seen” 9, or it is possible that other 9 can appear closer than the position which the number indicates?
    2) Team play-off: I would like to know the form of the one of the four corner 3×3 areas which Irregular Sudoku and middle Classic Sudoku shares; in Irregular sudoku, is it an outlined square (recognized as an one region) or not?
    3) I do hope that the following situation won’t happen, but if a competitor were to believe that there would be a problem with a puzzle in play-off rounds, what should she/he do?
    (e.g. write “Wrong puzzle” next to the puzzle and submit it to the checker, tell that to the checker, etc)

    Thanks a lot,
    Yuhei

    To be awarded points for each grid, on the completion of the round does the grids need to be physically piled up in the correct order, or it is enough to write in all the digits except cells with holes?

    1) If a no-solution grid is marked as having multiple solutions, does a solver get -24 points, or -38 points?
    And how about the opposite pattern (a multiple-solutions grid marked as having no solution)?
    2) It’s not a realistic situation, but if a solver somehow marks more than one area how the points will be given?
    For example, what if both no-solution and multiple-solutions are marked in correct/no-solution/multiple-solutions puzzle…
