THE RULES:
Ordinary sudoku rules apply: place the digits 1 through 9 in each row, column, and 3x3 bold outlined box.
Spinal tap rule (these all go to 11) applies to all further rules. Every sum is 11. To wit:
-Spinal tap renban rule: digits on a purple line are consecutive and sum to 11.
-Spinal tap zipper line rule: Pairs of digits in cells on a grey zipper line that are equidistant from the midpoint of the line sum to the same number, and that number is always 11.
-Spinal Tap Region Sum rule: digits on a blue line sum to the same number in every box, and that sum is 11.
-Spinal Tap killer cage rule: the digits in each killer cage sum to the clue in the top left corner, if given. If no clue is given, the digits in the cage sum to 11.
-Spinal Tap Roman numeral rule: Digits separated by the Roman numeral XI sum to XI.

Attention-to-detail in your coloring/pencil-marking is critical. It's so easy to make a mistake and then good luck in back-tracking.

Somehow my brain kept trying to make dominos that added up to 10, so I needed to restart several times. Once I got used to the 11 rules, it was really fun.
