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...

Sorry, I don't still understand the 16th question. Original, I have the same idea with Wicktroll. But after Para's reply, I was confused. Could anyone explain how you solve this puzzle at first 3 or 5 steps? thanks.

About Para's reply, he said "The rule only states that one of the neighbors of a GIVEN digit, must contain that digit." what is the GIVEN digit? thanks.

For example: 6 is GIVEN digit (left grid) on R6C1. This digit 6 in solved grid must be on R5C1 or R6C2 and for sure this 6 doesn't leave region (bottom left).
GIVEN 6 on R5C1 must move on some of next cells: R5C2, R6C1, R4C1. First digit 6 is on R5C1 or R6C2, so that leaves only R4C1 as position for second 6.
After that you can conclude that first 6 is on R6C2.

You can try to continue using similar logic...

About Movable Digits, in pictures

Any given digit in left grid, must appear at one of the 4 adjacent cells in the right grid.
In the grid below look at the marked cell with "A" in the left grid. It means, "A" must appear at least once in the marked cells in the right grid. (It could appear twice, but at least once).




Now here is the sudoku from the instruction booklet, with the solution next to it. You can see the rule being applied for each of the given digits in the left grid.
