PUZZLE NO. 307 : KILLER-KROPKI PAIRS-XV PAIRS HYBRID SUDOKU

 


RULES : Classic Sudoku rules apply. Additionally, 
  • Killer Sudoku rules apply, i.e., there are some cages in the grid. The number on the top left corner of each cage is equal to the sum of the digits in that cage. Digits do not repeat inside a cage.  
  • Kropki Pairs rules apply, i.e. if the absolute difference between two digits in neighboring cells equals 1, then they are separated by a white dot. If the digit in a cell is half or double of the digit in a neighboring cell, then they are separated by a black dot. The dot staying between 1 and 2 can have any of these dots. All possible dots are not marked. 
  • XV Pairs rules apply, i.e., if the sum of digits in orthogonally adjacent cells is 10, then they are separated by an X. If the sum of digits in orthogonally adjacent cells is 5, then they are separated by a V. All possible Xs & Vs are not marked;
