1234 Sudoku appeared in recent 10th World Sudoku Championship. Before this championship, I had not come across this Sudoku type, so I decided to create it for practice. I have kept design off two hearts for this Sudoku. Similar design I have used for one of my Classic Sudoku puzzle which I created last year for Sudoku Mahabharat.
This 1234 Sudoku, I am posting as 134th Sudoku in Fun With Sudoku Series.
