Normal sudoku rules apply. Cells separated by a knight's move (in chess) cannot contain the same digit. Digits on a (slow) thermometer do not decrease from the bulb end. Adjacent digits on a green line differ by at least 5. A cage shows its sum. A purple line uses a set of consecutive digits in any order. Digits on an arrow sum to the digit in the connected circle. Digits separated by an X sum to 10. Digits separated by a V sum to 5.
