Three is a Crowd Sudoku appeared in last year's Sudoku Grand Prix Championship 2014. This particular Sudoku is from my old collection and I prepared it around more than 1 year back.
Three is a Crowd Sudoku looks looks very similar to Outside Sudoku. However it differ from Outside Sudoku in the sense where one of the outside given number is incorrect and also exactly 9 different numbers are incorrect on each side. Anyway refer to Rules of this Sudoku to understand instructions of this puzzle.
This Three is a Crowd Sudoku is my 93rd contribution for The League of Extraordinary Ladies and Gentlemen.

## Rules of 'Three is a Crowd Sudoku'

Classic Sudoku Rules apply. Additionally, external digits show the three numbers to be placed in the contiguous box of the corresponding row or column. Exactly one digit for each triplet, however, is incorrect. On each side of the grid (top, bottom, left, right), the nine incorrect numbers are all different.
