Sum-thing's Wrogn

Rules

Normal sudoku rules apply. Normal rules apply for killer cages, sandwich sums, and arrows, except that for each clue, the indicated total (the number printed in the clue or given by digits in the arrow circle/pill) does not match the actual sum of digits. Instead, a clue's indicated total gives the sum of digits on one other clue in the grid (which may be a different clue type). No two clues have the same total.

Normal constraint rules:

• Killer cages: The indicated total gives the sum of the digits in the cage. Digits may not repeat in a cage.
• Sandwich sums: An indicated total above a column gives the sum of all digits between the 1 and the 9 in that column.
• Arrows: The indicated total, given by the number in the attached circle or pill (pills represent 2-digit totals read left-to-right), is the sum of all digits along the arrow.

Solve in f-puzzles or CTC.
