• Normal Sudoku rules apply.
• All cages are Killer Cages (digits may not repeat). All cages sum to a digit found on the thermometer. All digits on the thermometer are represented by at least one cage, but not all cage sums are unique. Some cages may sum to the same amount. Cages cannot sum to an amount that isn't a digit on the thermometer. Numbers on the thermometer cannot be on the thermometer unless there is at least one cage sum that matches it.
• Each of the numbers in a quadruple constraint must appear at least once in one of its four surrounding cells.
• Numbers on the thermometer must strictly increase from the bulb's end.
• Numbers on the colored Palindrome lines must appear on both sides of the line. If a number appears as the Xth cell from one end of the line, it must also appear as the Xth cell from the other end.
• All palindrome lines have unique colors. Palindrome lines may share cells with other palindrome lines' cells. All cells shared between palindrome lines are visible. Palindrome lines start and end strictly when the color starts and stops.
