Trimino Sudoku (Daily Sudoku League #43)

Thanks to Prasanna for testing all my puzzles for The League of Extraordinary Ladies and Gentlemen. One very positive feedback I have 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 at 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 new Sudoku type which appeared recently in one of WPF Grand Prix 2014 Sudoku champinship
This Trimino Sudoku is my 43rd contribution for The League of Extraordinary Ladies and Gentlemen.
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.

  1. Hi there. I really enjoy these puzzles but i am confused about the rules for bust sudoku. What is meant by a ccoresponding direction?? The right most column has a clue of 5. As one goes down column 9 the 5 is the second number ..... so the sum before the 5 is 4 and after the 5 the sum is 36.... so in one direction the sum is well under 21 and in the other direction the sum is well over 21

    1. For the Bust Sudoku, the outside number gives the number of cells for which one should be adding the digits so that the sum is greater than or equal to 21. For example if the outside number is 5, then we should be adding first five digits in that direction to get the sum just above 21. It means that if outside number is 5 and we add first 4 numbers then the sum will be less than 21. Do let me know if something is still not clear?
