I've made a few thermo variants. All are standard thermo sudokus + an extra rule. This is a sequel to the puzzle The Four Horsemen (puzzle #42). Check out the others using the following link:

Thermo Variant Series puzzles

Rules: Normal sudoku rules apply. Along thermometers, digits must increase from the bulb end.

Variant: Each thermometer has exactly ONE (and ONLY one) of the following properties:

1) Entropic: Any sequence of 3 successive cells on the thermometer must contain a low digit (123), a middle digit (456) and a high digit (789).

2) Renban: Digits on the thermometer must form a set of consecutive digits.

3) Region Sum: Digits on a thermometer in one box must add to the digits on the same thermometer in another box (Note: the thermo must cross a box for this to apply).

4) 10-line: The digits on the thermometer add to 10.

It is up to the solver to determine which thermometer has which property.
