Yes, the first puzzle has a unique solution without information from the second puzzle. |

In your different solution, have you taken into account that there must be a specified number of corresponding digits per row in both grids on the same page? |

Of course the XV has multiple solutions on it's own (without the grid to the left). You can see that even without solving. In a unique XV at least one of the givens has to be a 1,4,6 or 9. Otherwise you could use a permutation (1,4,6,9)->(9,6,4,1) to create another solution.

can anyone explain me Rules of Greater or lesser sudoku ? Only one of the rules is true. It is part of solving to figure out the correct rule. See Sudoku A or B IB for more details.

Location: India | so it means that only the two cells where clue is given in center are of importance. And then the clue is either greater or smaller than other digit that will be part of those two cells ? |

The number in the clue is greater than the other cell for ALL given clues
OR
The number in the clue is smaller than the other cell for ALL given clues

hie
i think entering 5 at r2c5 itself is a wrong step , in that row 5 can be at r2c8 :) |

Ah! No, I had not. I am notoriously bad at reading the full instructions ... even as I wondered what those numbers in the middle were doing there ...
