Classic Sudoku rules (1 through 9 in each column, row, and 3x3 box).

This puzzle features Thermometers, which means digits must be increasing along a thermometer, with the smallest digit on its bulb.

Additionally, the total value of all non-thermometer cells adjacent (orthogonal and diagonal) to a bulb are equal to the total value of the cells in the thermometer's arm (cells containing a thermometer but not a bulb). ie. a bulb adjacent to a 1 and 9 will have its length add up to 10, not including the bulb digit. Thermometers with two arms are part of the same total.
