Rules:
Normal Sudoku Rules Apply.
Place the digits 1 to 9 in each row, column and 3x3 box. Digits on a thermometer increase from the bulb end. The green line is a parity line. All digits on the line are from the same parity (odd or even). The inequality sign points to the smaller digit.
Draw a single orthogonal line that does not loop or intersect itself and passes through each cage exactly once. It may only enter and leave a cage once. It may not leave and re-enter the same cage. It must pass through all cells in each cage. All cages have unique values that do not repeat except one. One and only one cage value must repeat. Similarly, all cages must have unique digits except one cage. One and only one cage has a repeat digit.
The line must pass through consecutive cage values. As the line progresses, so do the cage values. However, one cage value will not increase but will be consecutive with the prior cage.
