Normal Sudoku rules apply. Digits on thermometers must increase moving from bulb to tip. 159 rules apply: Each digit in column 1 indicates the position of 1 in its row (that is, if R3C1 is a 6, R3C6 is a 1). The same is true in columns 5 and 9 of the digits 5 and 9, respectively.
Solution code: Row 1 followed by row 8, no spaces
