Recently I posted a Tens Sudoku puzzle. The Fives Sudoku puzzle is very similar to the Tens Sudoku puzzle in instruction but it is very different while solving this puzzle. In the Tens Sudoku, one has to take care of the sum of the number 10 and there is only 4 combination forming the sum as 10 e.g. 1-9, 2-8, 3-7, and 4-6 pairs makes the sum 10. However, in Fives Sudoku one has to take care of the difference of the adjacent number being 5 which make many combinations of number using which the number 5 can be obtained with addition or subtraction. While creating this Fives Sudoku puzzle I missed any combination which could produce 5 and ended up creating the puzzle with multiple solutions on my first few attempts :).
Fives Sudoku puzzle recently appeared in the 2nd round of WPF Sudoku Grand Prix 2016. This is when I prepared a few puzzles of this type to practice for this championship. There is one more puzzle that I created at that time. I will be posting the remaining puzzle soon here.
This Fives Sudoku I am posting in the Fun With Sudoku Series as the 190th puzzle in this series. Can you solve this Fives Sudoku puzzle?

## Rules of Fives Sudoku

Classic Sudoku Rules apply. Additionally, adjacent cells containing numbers whose sum or difference is 5 are marked. Adjacent cells with no marking must not contain numbers whose sum or difference is 5.
