Sequence Sudoku Puzzle (Fun With Sudoku #277)

Sequence Sudoku is one of the very old Sudoku types. It has appeared in World Sudoku Championships with different names or with slightly different rules. In one of the World Sudoku Championships (WSC) this Sudoku type was called Snake Sudoku and in another WSC it was called Consecutive Sequence Sudoku. However, Sequence Sudoku differs slightly in rules from Snake Sudoku and Consecutive Sequence Sudoku. While in Sequence Sudoku difference between numbers falling on-line can be anything, in the other two variations, this difference is restricted to 1. Today's Sequence Sudoku is one of my recently prepared Sudoku puzzles. This Sequence Sudoku puzzle I am publishing this as part of the Fun With Sudoku Series as the 277th Sudoku Puzzle in this Series. The theme of this Sequence Sudoku puzzle is Pine Tree.
