Normal Sudoku rules apply. Digits along the thermometer must strictly increase from the bulb. There are four thermometers which share a bulb. Digits along an arrow must sum up to the digit in the circle attached to that arrow. Each blue line is divided by box borders into segments. Each segment on a blue line must have the same sum of digits but these sums may be different for different lines. Each purple line contains a set of consecutive digits in any order. Adjacent digits along a green line must differ by at least 5.
