Interesting IB........
I am not able to understand the rules for DISJOINT..........
Disjoint is also known as "Offset" sudoku. Lets take cell R1C1 for example. That cell is top left corner of Box 1. Lets assume that it contains number 1. So in short the number 1 cannot repeat in any top left corner of boxes 2 to 9. (R1C4,R1C7,R2C1,R2C4,R2C7,R3C1,R3C4 and R3C7 ) . Hope this clarifies.

Country : India | Note for paper Solvers : As discussed here, we have added 2 text boxes for each grid.
For the answer key, it will either be 2 rows, or 2 column or a row and column.
When filling in the answer key using the text boxes, please note that
If the Answer Key is 2 rows, then please fill the top row first and then the bottom row next.
If Answer Key is 2 columns, then fill the left column first followed by the second column.
If the answer key is 1 row and 1 column, Then fill the row first followed by the column.
This is to ensure there is no confusion when submitting answers.
There is no change for online solvers.

R6C6 is a 7 I think (5 is in R4 in the same column )

Zalak,no 2 adjacent cells can be consecutive. Even if they are across 2 boxes. Fred was correct when he said that R6C6 is a 7 not a 5.

Country : United States | motris posted @ 2011-02-13 1:24 AM I have two instant reactions to this test. First, absolutely incredible puzzles, beautifully constructed and amongst the best I've ever solved. Phenomenal job Rishi. Second, I'm kicking myself for answer entry problems which spoiled a much better score. Not the fault of the new entry mechanism. Just bad transcription from paper. |

Thanks a lot Thomas... Means a lot coming from you.... and yes... I was awake keenly watching you solve... Your timing was not far off from my estimate.... then I saw the entry typo... was sitting here hoping you notice it and you eventually did ... Great job once again Thomas..
