Normal sudoku rules apply. Along a peach line, the digits between (not including) the green circles sum to a two-digit number; these two digits appear in the green circles in either order. In this puzzle, the lines are also entropic (including the green circles). Any three adjacent digits along a line must contain one small digit (1,2, or 3), one medium digit (4,5 or 6) and one high digit (7,8 or 9).
