Country : India | rvarun posted @ 2014-09-05 6:46 PM Thanks guys for the explanation and example. With respect to T-Crossword Sudoku, I assume that all combinations of words that will fill up the 81 cells will be given. Can you explain the following line.
Within each bold-lined 3×3 square, the cells occupied by letters (numbers) must form a ”T” in any one of 4 possible orientations. --> How this T is determined. What must be the numbers forming this T.
One letter (number) is already placed, and all words must be used. --> Is it one number per T or one number per 3x3 or one number per word. |

Within each bold-lined 3×3 square, the cells occupied by letters (numbers) must form a ”T” in any one of 4 possible orientations. --> How this T is determined.What must be the numbers forming this T. It is part of the solve to determine how the T is oriented.But just by looking at the example you can safely assume that this T is completely formed by numbers which are given outside the grid. One letter (number) is already placed, and all words must be used. --> Is it one number per T or one number per 3x3 or one number per word. It can be any of the 3.The deduction that you can arrive at by looking at the 5 which is given in the grid is that the T can be oriented in only 2 out of 4 possible ways.Because in the other 2 ways , 5 won't be a part of the T.The next logical question that you might ask is why should 5 be a part of T ?.Look at these sentences together and you will understand why "Within each bold-lined 3×3 square, the cells occupied by letters (numbers ) must form a ”T” in any one of 4 possible orientations.One letter (number ) is already placed" (It is implied that the one number which is already placed is part of the T ) If it helps,try reading this sentence in the IB "Within each bold-lined 3×3 square, the cells occupied by letters (numbers ) must form a ”T” in any one of 4 possible orientations" in this way--->"Within each bold-lined 3×3 square, the cells occupied by letters (numbers ) must form a ”T” comprising only of numbers or part of numbers given outside the grid (Read from left to right or top to bottom ) in any one of 4 possible orientations". |

In Rolling the Dice Sudoku: The two adjacent shaded digits should be such that they are adjacent on the dice is implied right ?
Correct.
For me it's still unclear. So does the dice needs to be rolled exactly according to the numbers on the dice and the next number must be exactly adjacent digit of the dice according to where I roll it? Or does the next digit just needs to be any adjacent digit?
I hope my question is clear. Sorry, if it's a stupid question.
Tiit
Your statement "the dice needs to be rolled exactly according to the numbers on the dice and the next number must be exactly adjacent digit of the dice according to where I roll it" is CORRECT.
Try out these examples:
In the top left image, if the 5 is replaced by 2, is that valid?Similarly can I replace 2 by 5 in the bottom middle image and 5 to 2,1 to 6 ,2 to 5 in the bottom right image?

See the first two images (top-left and top-centre ). One has '5' and one has '2'. One is right and one is wrong. Maybe you should take an actual die and figure out why. |

Sudoku Day has started.
This thread will remain unrestricted during the test, so that questions from players, if any, can be answered quicker. Please note however that organizers / authors will not be available round-the-clock. It is best to ask the questions before you start the test than asking it after you start.

Country : United States | Thanks! I don't expect to be able to complete them all anyway, but it's makes me glad that there is at least a *hope* that I won't have to skip a puzzle that seems particularly fun just because I realize that I can't quite figure out the rules...

That's precisely what I tried doing, but unfortunately I did not have dice in my possession.That has been taken care of now by sticking numbers on the 6 faces of a cube! (which I had by the way ).The next instant I understood how this sudoku works.Thanks a lot Rohan!

Country : Serbia | Nikola posted @ 2014-09-10 7:44 PM LMI September Sudoku Test - Sudoku Day 2014 is now over. 241 players participated, 160 non-zero scores.
Congratulations to deu (Hideaki Jo from Japan), Kota (Kota Morinishi from Japan) and Semax (Sebastian Matschke from Germany) for taking the top 3 places. There were several very hard new sudoku variants but deu and Kota managed to complete the test much before end of time.
I'd like to again thank my test solvers Goran Vodopija, Zoltan Horvath and Rohan Rao (he solved all 9 grids in 98 minutes).
Thank you all for participating. I hope you enjoyed it as much as I creating new variants and following the live results.

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

Country : Switzerland | Fred76 posted @ 2014-09-11 12:50 AM Thanks for the very nice tournament.
It was fun to have a tournament with only new variations.
My strategy was to solve all sudokus in the order except T crossword which is too puzzlish for me.
I broke the second even product 2 times and had not enough time to try the T crossword during the tournament.
I already look forward to take part in the tournament next year
