Normal Sudoku rules apply. Place the digits 1 through 9 in each row, column, and box.

Thermometers: Digits along a thermometer must strictly increase from the bulb to the tip.

Region Sum Lines (Blue): Box borders divide blue lines into segments. Each segment of a given line must have the same sum (this sum may be different for different lines).

Alternating Parity Line (Red): Digits along the red candle must alternate in parity.

Constant Parity Lines (Purple): Digits along a purple candle must have the same parity.

8-Line (Brown): the brown line consists of contiguous groups of cells, each of which sums to 8. Groups cannot overlap. Additionally, the digits 1-8 must appear on the brown line at least once.
