My first Sudoku. Inspired by Cracking the Cryptic.

Rules:

Normal Sudoku Rules Apply: Each Row, Column, and 3 by 3 box in the puzzle must be filled with the digits 1-9 without any repeated digits.

Some cells are grouped into a cage, with a specified sum. The numbers within the cage must add up to the given sum and numbers may not repeat within the cage.

Digits in cells separated by the white dot are consecutive. Digits in cells separated by the black dot have a 1:2 ratio.

The Center cell of the the grid is a "Minimum Cell" and must contain a number lower that any of the 4 orthogonally adjacent cells.

Along green (“German whisper”) lines, digits must differ from their neighbors by at least 5.

Purple (“renban”) lines must contain a non-repeating set of consecutive digits in any order.

The sum of the digits along an arrow is equal to the digit in the connected circle. Digits along an arrow can repeat if allowed by other rules.

Cells Separated by a "V" sum to a total of 5. Cells Sparated by an "X" sum to a total of 10.

The (blue) Arrow in c7r3 continues through c6r4, c7r4, and c8r5; The (red) Arrow in c6r4 only goes through c5r3 and c4r3
