Killer (Hidden Arrows) Sudoku by clover!
(This post is part of the Genuinely Approachable Sudoku (GAS) series.)
There is something extra going on to organize the numbers in each Killer cage in this “Hidden Arrows” variation by clover! Can you calculate all the numbers to get to the solution?
or solve online (using SudokuPad)
Author/Opus: This is the 50th puzzle from Clover, part of the Genuinely Approachable Sudoku (GAS) team.
Rules: Standard Sudoku rules: Insert a number from 1 to 9 into each cell so that no number repeats in any row, column, or bold region. Also, the sum of the numbers in each cage must equal the value given in the upper-left corner of that cage. Numbers cannot repeat inside a cage. Each cage has a hidden arrow (as in Arrow Sudoku) with a circled cell at one end of the cage and an arrow path that travels through edge-adjacent cells through all other cells in the cage. The value in the circled cell must equal the sum of all other numbers in the cage (as would be on the arrow’s path).
(For example, in this puzzle, either R4C3 = R4C4+R4C5 or R4C5 = R4C4+R4C3.)

“Each cage contains a number equal to exactly one half of the cage’s given sum. This number is located at one end of the cage.”
Seems neater, at least to me. Don’t need to mention Arrow Sudoku at all; it’s not like there are any actual arrows there.
We had to mention Arrow Sudoku because GAS is taking from public names of these genres for their guessing game.
Otherwise I fully agree the history of this puzzle and the rules are not helped by drawing arrows. We put them in the solution file but don’t expect many saw them.
