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.

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) ?

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.

Very hard set. I broke at least 2 of the puzzles, dumping something like 25 minutes total into them.
