Normal sudoku rules apply. Digits along an arrow sum to the digit in that arrow's circle. A purple line contains a set of consecutive digits, in any order. Adjacent digits on a green line must have a difference of at least five. Any set of three adjacent digits on an orange line must have one digit from each of the following sets: 123, 456, 789. Digits on a red line must have a value between the values of the digits in that line's circles. Box borders divide a blue line into segments with equal sums. Digits joined by an X sum to 10; digits joined by a V sum to 5. Digits joined by a white dot must be consecutive; digits joined by a black dot must be in a 2:1 ratio.
