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.

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.


There is an error in the example. There is a 3 where there should be a 4 in the puzzle. I came upon this error when, in the first two columns, there was no 4. Therefore, because no 4 could be entered legally in the first column, the demo has no valid solution. This is confirmed with five 4s and seven 3s in the puzzle layout.

Additionally, I find it hilarious that my own posts are restricted from my view during the test. LMAO

Very nice tennis theme through all puzzles.
It will be interesting to watch results if someone will solve all puzzles in time limit, because this time it will be difficult quest I think.
Little Killer got me, I spent a lot of time there and couldn't solve it, but I had to try for that massive 157 points.
Almost same happened with Movable digits, but luckilly I solved it. And it was my favourite puzzle from the set (together with Frameless).

Thanks for great test!

I'm embarrassed that I missed so many of the tennis references during the test... after time ran out I asked my fiancee (who also competed) what she made of the recurring 15-30-40 and then everything clicked and I started to notice the theme in puzzle after puzzle...

Like Gotroch, I gambled on the Little Killer, but for me it paid off. Looking forward to solving the ones I skipped at a leisurely pace. My compliments to the chef!
