Nikola further suggested that the winner of this year's contest should be given the opportunity (or challenge ) to write the contest for next year. I think that is a very nice idea. At the same time, it is not a rule (it is not written in the IB  ), just a suggestion at the moment from Nikola, me and others at LMI.
Careful... let it not demotivate players to vie for the top spot ;-)
On a serious note, I think its a nice simple idea and I hope the trend catches on! |

This test is an exception - we are not going to have samples as mentioned in the IB. |

Location: India | Oh, yes. I didn't notice that part in the booklet. BTW can you give more elaborate explanations for the rules in T-crossword, aspirator and diagonal path sudokus? |

Hi Mohan, Please be specific with your questions. If you can post the exact difficulty you are facing while trying to understand the rules, we will be able to answer. |

Location: India | "Each number from the top row of the grid has its own diagonal way(at least one) throughout the same numbers to a couple in the bottom row." This is in the diagonal path sudoku. What does this mean? |

"Each number from the top row of the grid has its own diagonal way(at least one) throughout the same numbers to a couple in the bottom row." This is in the diagonal path sudoku. What does this mean?
In image below, see how the 3 in the top row can be connected to the 3 in the bottom row diagonally. Similarly 6 in the top row can be connected to 6 in the bottom row diagonally.
At least one such diagonal path must exist for each number in the top row.

Location: India | "to a couple in the bottom row",what does this mean? And in your reply, you mentioned "Similar diagonal path (at least one) must exist for each number in the top row." . Can you also illustrate this?

Location: India | Moreover, since in a sudoku one digit can appear only once in a column and row, the path will always be diagonal. Why do you keep mentioning it? |

"to a couple in the bottom row",what does this mean?
That probably needs to be phrased differently, but the rule means is the numbers in the top row has to be connected with the corresponding number in bottom row.

And in your reply, you mentioned "Similar diagonal path (at least one) must exist for each number in the top row." . Can you also illustrate this?
In image below, 2 different paths exist for 6, one in red, other in blue. This is valid. More than 1 path may exist for a number, but there should at least be one.

No particular reason why I mentioned it so many times (Possibly because in most puzzles involving paths/loops, paths always consists of vertical/horizontal segments) |

Location: India | OK :). I have two more questions. In the aspirator sudoku, what do you mean when you say the aspirator sucks up cells? That is, how do the aspirator and the sucked cells change after the aspirator sucks them? |

Nothing changes actually. Numbers in aspirator or sucked cells do NOT change.
It just means number in "the aspirator cell" is greater than numbers in all the "sucked cells". Also, all possible sucked cells in 8 directions are given. "Suction" stops when they hit the wall or a number >= the aspirator cell.

But, don't certain instructions seem misleading or far-fetched or is it just me? None of the above.
These are 9 never seen variants, and we expected many more questions about the rules than what we have seen so far. |

Location: India | OK, then let me add to the question count. This is in the T crossword sudoku:"Place the given list of words into the grid (across or down) to form an interlocking crossword, so only the words in the list are formed and no others." "only the words in the list are formed": does it mean the relative positions of the digits in the word must be preserved? And if the word is "451" ,are both "451" and "154" valid? |

Location: Indonesia | I'm pretty sure that you cannot reverse the words, just like in regular word placing puzzles (and in particular T for Trees, the inspiration for this variant) you cannot reverse the words. |

No, '154' is not valid. The numbers should be formed either across (left-to-right) or down (top-to-bottom) in the standard crossword-style. |

Location: Estonia | This ""Suction" stops when they hit the wall or a number >= the aspirator cell." sentence is confusing for me.
So, as I understand, it starts sucking at some point and goes clockwise (anticlockwise) until it hits greater or equal numbers or the wall and then stops even if there would be more smaller numbers on the way? Do we have to figure out by ourselves in which way it must go and where it starts? Although the example is totally confusing to understand that sentence.
Also the quiestion about diagonal path. Can the path turn direction if it hits the wall?

No, the path cannot turn if it hits a wall.

There is no clockwise/anticlockwise. You need to look in the 8 directions from the marked cell.
Check these two examples below. See if you understand:

Location: Estonia | Oh, ok. Big thanks. I think I got it now. I was looking totally in the wrong direction. These images are good for explanation.
