Rules:

Normal sudoku rules apply. Digits increase along a thermometer starting from the bulb end. Digits along an arrow must sum to the digit in that arrow's circle. Clues outside the grid show the sum between the numbers 1 and 9 in that row or column, respectively, and at the same time also show how many digits are 'seen' at that direction with higher digits blocking the lower digits from view (i.e if it is on left side means from left to right, if it is on top side means from top to bottom). All these kind of clues on left side and top side are given (i.e. there isn't a clue that is missing). '?'s are digits 1 to 9 which must be determined by the solver.
