Some people are so good in solving Sudoku that many times they will be able to solve the Sudoku variation with only Classic Sudoku rules. Prasanna is one such Sudoku player. He is such a good player that for many of my Sudoku variations which I send him for testing, he is able to solve these without using variation rules. This Symmetric Unequal Sudoku is such puzzle which I tried to create as variation. However he is able to solve it only using Classic Rules. I am publishing this Sudoku as variant. However I am sure that many of the good Sudoku player will be able to solve this puzzle as pure Classic Sudoku puzzle.
I am posting this Symmetric Unequal Sudoku  as 80th Sudoku in Fun With Sudoku Series.
Rules of Symmetric Unequal Sudoku
Classic Sudoku Rules apply. Additionally there are 40 pairs of cells symmetric according to a 180° rotation. Two digits in such two cells should be different.
To understand rules more clearly consider two Main Diagonal as mirrors. Digits in a particular cell and its mirror image should be different.
