Thanks to Prasanna for testing all my puzzles for The League of Extraordinary Ladies and Gentlemen. One very positive feedback I got from him is that hints given in Sudoku should be symmetrical.  So now I try to create Sudoku with symmetrical hints. I started creating this Sudoku keeping in mind this feedback but in the end, I found that to make this Sudoku unique I need to add two more hints which made this Sudoku asymmetrical as I don't want to add corresponding symmetric hints to avoid this Sudoku being very easy.
Trimino Sudoku is a new Sudoku type that appeared recently in one of the WPF Grand Prix 2014 Sudoku championships
This Trimino Sudoku is my 43rd contribution to The League of Extraordinary Ladies and Gentlemen. Can you solve this Trimino Sudoku puzzle?

## Rules of Trimino Sudoku

Place a digit from 1 to 6 into each empty cell or blacken the cell so that each digit appears exactly once in every row, column, and outlined 3x3 region along with three black cells. Each black cell should be part of an orthogonally connected group of three blackened cells (a triomino). No two triominoes can share an edge.
