Rossini Sudoku is a variation of the classic sudoku. The arrows outside the grid indicate that the nearest three digits in the corresponding direction are in ascending or descending order (the highest number is always in the direction of the arrow). All possible arrows are given, so if there is no arrow, the first three digits do not form an increasing sequence in either direction.

Additional Rules:

• Anti-King Sudoku ("Touchless Sudoku") equal digits can be neither orthogonally nor diagonally adjacent.
