prasanna16391 - 2013-08-05 7:06 PM It will be exactly same layout. The organisers have decided not to throw surprises after the IPC. 2 things - In overlapping Sudoku - Do we assume that the overlap will be "clean" like the IB example, or is it possible that it will cut into boxes? (e.g. I think the one at the WSC in 2012 had just 2 rows/columns that weren't overlapping, instead of 3 as in the example) prasanna16391 - 2013-08-05 7:06 PM Answer key for Overlapping Sudoku can be 9 digits or 12 digits. Answer keys - Again, in Overlapping Sudoku, I assume that the non-overlap parts will also need to be entered, making the key possibly longer than 9 digits? Also, in Smashed Sums Sudoku, how should the black/blank cells be denoted in the key? Smashed Sums Sudoku : Enter X for black cells, although you will also be awarded points if you enter anything like 0 or - |

There is no option to mark 7 in smashed sums sudoku. instead there are two options to mark X and . which i think both to mark blank cells. Please check it. |

Dileep Singh - 2013-08-09 11:48 AM instead there are two options to mark X and . I think this is there for a reason. You can mark black cells with X and mark a . for where you think a number should be (as in, not black) and that marking will certainly help in solving this one. |

debmohanty - 2013-08-09 2:49 PM Congratulations on your blue star Thanks I just checked the submission page. There seem to be points assigned to each Sudoku there. Since these aren't updated into the IB, I assume these aren't the final/official points distribution? |

deepika m - 2013-08-09 3:49 PM what is sudo-kurve?not getting it. There are 9 distinct digits in each 3 groups of 3 cells that are connected by gray lines. Example of this - The first row of the top left box, the 3rd column of the middle box and the first row of the bottom right box are connected by a bending gray line, and so there need to be all digits from 1-9 in those 9 cells. |

deepika m - 2013-08-09 4:41 PM still not getting it.my doubt is whether it's a 9x9 sudoku or not. I suppose it is more of a free-form type but the range will always be 1-9 as in the example. The example has just 3 boxes, but it has in all 6 different sets of 1-9 as Ravi pointed out. If you google Sudo-kurve you'll see many other possible layouts, the base theory in all being that there are such sets of 1-9 formed by the connecting gray lines. |

Hi! In smashed sums sudoku,can the shaded cells be orthogonally adjacent?It is not explicitly stated in the rules that they can't be.So i assume they might be when a sum is not given?!Also in the example puzzle i dont see that case happening as all row and column sums have been given already/// |

kishy72 - 2013-08-09 5:37 PM Firstly, unlike the example, there will be some rows or columns without any outside clue in the actual puzzle. Hi!

They could be adjacent or not be adjacent, in that row / column. |

deepika m - 2013-08-09 4:41 PM still not getting it.my doubt is whether it's a 9x9 sudoku or not. Deepika, not all sudokus need to be 9x9. There are so many variants which do not conform to this design. For example, Isosudoku, Snowflake sudoku. The only constraint we need to remember is that the digits do not repeat along the path denoted by the grey lines. Rishi |

One question related to 6x6 Sudoku point distribution. Will the 100 points given only when all the 6x6 Sudoku solved correctly or each given mini Sudoku will have some points assigned to it? |

rajeshk - 2013-08-10 2:17 PM They are all independent of each other. Points are assigned to each of them. You get points for what you solve. One question related to 6x6 Sudoku point distribution. Will the 100 points given only when all the 6x6 Sudoku solved correctly or each given mini Sudoku will have some points assigned to it? If you have logged in at the submission site, you would have noticed that there are 6 of them, and the points are as shown below. (Top) 5 + 10 (Middle) 15 + 25 (Bottom) 25 + 20 |

I had a question on the Bonus points. It says that all answers with a maximum of 4 wrong cells will get the bonus of 7 points per minute saved. Now I assume the 4 cells are related to the answer keys that we key in. So do we get full points for a puzzle if we key in a wrong answer with a digit mistyped or do we get partial points or 0 points for the puzzle yet eligible for time bonus?
