*** TODAY'S PUZZLE ***

Rules
Normal sudoku rules apply. Digits along an arrow sum to the digit in that arrow’s circle. Along orange lines, every set of three adjacent cells contains one low digit (1,2,3), one middle digit (4,5,6), and one high digit (7,8,9). Digits in cells with a shaded square are even.
