If someone asks you whether Sudoku is a Logical Puzzle or Mathematical Puzzle, what will be your answer?
I have seen many people answer that Sudoku is a Mathematical puzzle. Math has nothing to do with Sudoku. It is purely a logical puzzle. It only uses numbers and that also can be replaced with alphabets or shapes it makes is entirely independent on Mathematics. However, there are many Sudoku variations which use Mathematics calculations to solve the puzzle. Average Sudoku is one of such Sudoku variation which uses the average of numbers to solve this Sudoku type. It is not only Mathematical Sudoku variations but also a Converse Logic Sudoku variations. It means that all the digits which are the average of its neighbouring numbers are marked.
Anyway, in the last few months, I have created many of the Average Sudoku puzzles. Some of these puzzles are already published here and some of these puzzles will be published soon. This index page, I will be using to give links to all these Average Sudoku puzzles.

Rules of Average Sudoku
Classic Sudoku Rules apply. Additionally, if the number in a cell equals the average of its two horizontal neighbours then the cell is marked with a horizontal line. If the number in a cell equals the average of its two vertical neighbours then the cell is marked with a vertical line. All possible lines are marked.
