Two important notes:
1. Examples in IB are taken from various sources.
2. Authors had excellent test solver who also reviewed IB and PB, so Nikola prepared appropriate gift for him

Hi everybody,
I have one question on the ninth sudoku - Frameless: What does mean this sentence? "The amount of digits can differ from sum to sum and CAN BE ONLY ONE DIGIT." I believe, that I understood the rules, but the ending of this sentence worries me.
Thanks a lot.

If the number outside is 7, for example, then the first digit could be 7, or they could be 34/25/16/124 in various permutations. So the sum can be the sum of a single digit.

Numbers outside the grid are sums of some number (from single digit to all nine digits) of digits from that side of grid (first N numbers).

Fred, Branko, thank you. I got the rules at first, but then wondered why it is said, when it is clear. I need to improve my English first

Hi everyone,

I have a question about puzzle 16 Movable digits. The puzzle rule says (I'm sure I misunderstand it...):

"However, for any number placed into the grid, at least one of its (at most) four edge adjacent neighbour cells must contain same number in the solved puzzle as the cell itself has in original grid."

Could you please tell me why there's a 1 in R3C1 in the solution grid? I tried to understand this rule in 2 ways, but
1. None of the neighbours of R3C1 is 1 in the original grid.
2. None of the neighbours of R3C1 contain the same digit in the solution grid as in the original grid.

The rule doesn't apply reversely. The rule only states that one of the neighbours of a GIVEN digit, must contain that digit. This doesn't mean that every cell must be one of its given neighbours as equal digits can transfer to the same cell. For example look at R5C5. The clues in R4C5, R5C4, R5C6 and R6C5 all move to this cell.

I tried to solve the IB (not only to read the instructions). When solving the puzzles number 4, 10, 11, 12, 13 and 14 I realized that I am not able to read my digits and pencil marks (all written by pencil), because the grey colour is too dark. Would it be possible to use a little bit lighter grey in the PB, please?

We'll prepare version 2 of IB with lighter grey to check is it better and after that define grey for PB.

Updated version of IB uploaded, with gray cells being 25% gray. (Images for 13 Placement and 14 Thermo are not fixed, but they will use 25% gray in the puzzle booklet).

Hope it is better.

About word search:
1.The rule says that Find all given words. Do I really have to find all the words or do I need to solve the sudoku? Or you just want to say that it's not solvable if you don't find all the words?
2. What do you mean about Find all given words (only words with capital letters) in the words list? Do I have to find all the words or do I have to find only the words with capital letters. The rule speaks against itself.

1. I guess we have to read it as "words can be found in the grid and you'd better search them if you want to solve the sudoku", indeed.
2. I may be wrong but I suppose there will be something like a text accompanying the competition puzzle, with only some words in capital letters.

All words written by capital letters (there will be additional words in competition puzzle, that you can completely ignore during solve) are placed somewhere in solved sudoku. You don't need to mark words in solved grid. It is enough to solve sudoku according to this additional rules.

For example: BUENOS Aires, New YORK. Only BUENOS and YORK must be in solved sudoku.

About New YORK, actually the capital letters are NYORK, do I need to find N_ _ YORK somewhere, or NYORK somewhere (how do I need to take blanks). Or what if there is like SeRbIa, how do I have to act then? I just don't have it clear and I would like to avoid unpleasant surprises.

Tiit, sorry if I confused you. There will be no surprises in competition puzzle. Words completely written using CAPITAL letters must be found somewhere in solved grid.
For New YORK, you need to place YORK somewhere in grid.

In the IB, rules of sudokus: "placement (shape) sudoku", "thermo-sudoku", "killer sudoku" and "movable digits" contain words "bolded region" instead of "bolded 3x3 box".

Will they all be irregular or is it just a little lack of precision of rules (examples have 3x3 boxes, except movable digits)?

Can we know exactly which sudokus will have irregular regions (example of movable digits has irregular regions, but the actual puzzle in WSC 2011 had 3x3 boxes)?

Thanks,
Fred

Movable digits has irregular regions, all other sudokus are with 3x3 boxes.

P.S. In all three sudokus (placement, thermo, killer) will be some non-box shapes for sure...
