Logic Masters Deutschland e.V.

Thanks to Scojo for the inspiration for this puzzle! as this puzzle was set for their weekly prompt.

Rules:

Normal sudoku rules apply. Place the digits 1 to 9 in each Row, Column, and 3X3 box.

All the arrows in the grid are Average Arrows. Grey arrows are also Ten-Lines, and orange arrows are also Entropy Lines. Circles are part of the lines.

Average Arrows: The digit in a circle represents the exact arithmetic mean of all digits along any individual arrow emerging from that circle.

Ten-Line: A gray ten-line must be divided into one or more contiguous groups of cells that each sum to 10. These groups of cells cannot overlap.

Entropy line: Each set of three consecutive digits on an Orange entropy line has to contain a low (1,2,3), a medium (4,5,6), and a high digit (7,8,9).
