Rossini Sudoku is very interesting Sudoku type in which converse rule of Sudoku solving is used. It means that all the possible arrows has been given. This Sudoku type appeared 6 years back in World Sudoku Championship and after that not much puzzles of this type were seen in many of the Sudoku contests. I like this Sudoku type and recently have created few Rossini Sudoku puzzles which I will be posting on this website soon. On this page I will be putting the links to Rossini Sudoku puzzles posted on this website.
Rules of Rossini Sudoku
Classic Sudoku Rules apply. Additionally the arrows indicate that the nearest three digits in the row (column) are in ascending or descending order (increasing towards the direction the arrow is pointing towards). If there is no arrow outside a row/column, the nearest 3 digits therein cannot be in either ascending or descending order.
