Also known as Hexagon Sudoku. Note that when Hexagon Sudoku was invented it was called "Isosudoku," under the idea that "Iso-" was a prefix meaning "equilateral hexagon." Although many isometric projections do incorporate hexagons, there is nothing inherently isometric about putting hexagons together.

Rules:
Place numbers in the grid such that every row, column and 3x3 box contain the numbers 1 to 9. Digits do not repeat along the diagonals in which the hexagonal cells share edges (from top-left to bottom-right, even if the diagonals contain less than 9 cells).

Inserire i numeri in modo che ogni riga, colonna, settore contenga i numeri da 1 a 9. Anche le diagonali formate dalle celle esagonali che condividono un lato(da alto-sinistra a basso-destra, anche se le diagonali non hanno 9 celle) non possono contenere numeri uguali.
