Sarah said "Set S starting sudokus!" So Scojo set Symmetrical Sandwich Snake Sudoku!

• Sudoku: Place the digits 1-9 once each in every row, column, and 3x3 box.
• Symmetrical Sandwich Snakes: A Symmetrical Sandwich Snake is a one cell wide, orthogonally connected group of cells that does not branch or touch itself, even diagonally, and exhibits 180 degree rotational symmetry about its center, which is given as a circle. Symmetrical Sandwich Snakes do not overlap each other and are always at least two cells long.
• The digit in a circle indicates the number of cells that make up the Symmetrical Sandwich Snake.
• The number in the top left corner of a circle indicates the sum of the digits physically between the highest and lowest digits on that Symmetrical Sandwich Snake (Like a normal sandwich clue, but on a snake). Each Symmetrical Sandwich Snake may only contain one each of its highest and lowest digits, but other digits may repeat.
