I promised something easier this week and I think this should be good. This Thermo-Sudoku has a simple opening that should give away a few quick digits. I was trying to make it without any given digits, but the given layout wouldn't allow it. The one central 5 made it unique though and it fits with the decreasing size of squares. It might be possible to line up the thermometers to make it unique without digits or by adding an extra one in the center, but I like how it turned out. I just hope I haven't misjudged the difficulty again, as I have done before. Enjoy.

Rules for Sudoku
In this Sudoku, there are a number of thermometers. Along each thermometer, digits have to be strictly increasing from the bulb upwards.
