A Scojo setting prompt where we were to collaborate with new people. I had a great time with Matt Tressel (aka MSDOS) setting this. Matt suggested a variant on entropy lines, and I suggested a constraint originally I saw from juggler. Thank you to all who tested!

Rules:

• Normal sudoku rules apply.
• Silent Serial Killer: Digits may not repeat in cages. If the sum of a cage is a 1-digit number, that number must be in the cell pointed at by the cage's northwest corner. If the sum is a 2-digit number, it must be in the domino formed by that cell and the one to its left. (Example: if the sum of the cage in Box 3 was 9, then r1c6 would be 9. If it's sum was 12, then r1c5 would be 1 and r1c6 would be 2)
• Tentropy Lines: Every set of 4 adjacent digits on a peach line must contain a digit from each of the X-pair (ten-pair) subsets of {1,9}, {2,8}, {3,7}, and {4,6}. A 5 may not appear on a tentropy line. Digits on a line may repeat if allowed by other rules.

Below is an example of how cage totals work for clarification. The yellow cells are the totals of the cages they touch diagonally.

All feedback (positive or critical) appreciated!
