What is killer sudoku and how to solve?

• it starts with an empty grid and only given the sum of caged cells written in small font on the upper left corner of the cage. 
• No number can be repeated in any row, column, region or cage. 
• You have to work out the summation and find the numbers in the cage, region, row, and columns. 
• Of course, you will use every tip and trick used for traditional sudoku and more. 
• There are many tips to solve traditional sudoku especially elimination and exclusion and logic
• But for killer sudoku, the rule of 45 and unique sum are the most important clues to solve the puzzles. 

• Diagonal Sudoku or Sudoku X has an extra rule where the numbers 1 to 9 must fit in the diagonal lines and no repetition of any number in the diagonals marked by the gray X lines.  
• Jigsaw Sudoku the 3x3 blocks are no longer square, instead it’s irregular region of 9 cells. As twisted as it sounds, these puzzles are challenging and addictive.
• Killer Windoku has extra four (3x3) blocks (shaded) where the numbers 1 to 9 can fit in without repetition.
• Girandola Killer Sudoku has an additional rule where the scatted shaded cells must contain the numbers 1 to 9 with no repetition in those shaded cells.
• In the Anti-diagonal variation, the diagonal lines should only have at most three different numbers. Repeated numbers are okay in the diagonal line, that is why it’s called anti-diagonal.
