Location: France | Looks great, but... the example for 1-2 Log Sudoku seems to have multiple solutions? I seem to have another solution with rows 1432,2341,4123,3214. Or am I misunderstanding the rules? |

The example changed at the last moment. This is really bad. I will return the original example, albeit without stripes with the same parity.

Location: India | Nice contest. Have a few queries.
I) In Log sudoku, suppose the strip falls into category b), would it be easy to discern the direction or could it also be ambiguous ? For example, if there is a 3x3 box, how do you arrange in ascending or descending order ?
II) In Pin sudoku, if a block is rotated, does a 6 become a 9 or it would still be a 6 (I assume it's the former but still would like to get it clarified)
III) In the 6th sudoku, does the value of N match between grids (i.e.,7 digits of let's say Row 1 will match exactly to 7 digits of Row 1 of second grid or it could also be a case of 7 digits of Row 1 to any other Row in grid 2) ?

Location: United States | I don't see that anyone's mentioned it yet, but the solution for SSC sudoku is clearly wrong, yes? The 3 and 4 in the leftmost column should be switched. |

I) The numbers increase from one end of the strip to the other. The direction is to be determined for each strip.
II) Yes, the number 6 after the turn can become 9.
III) Matches. |

Yes, of course, thank you! |
