Coordinates Sudoku - Loops

Place a digit from 1 to 9 into each cell of the grid so that every row, column and outlined 3x3 region contains each digit exactly once. Each of the 9 regions is associated with one digit, shown as its background. Inside a region, if two neighboring digits – orthogonally or diagonally – are the coordinates in the grid of the associated digit, a line must join them. In this puzzle, the coordinates (1,1) indicate the top left corner of the grid. Example Since 2 and 6 are joined by a line in the 1 region, one or two of the cells marked by a star must contain a 1. Since 6 and 8 are neighbors in the 1 region but are not joined by a line, the cells marked by a cross cannot contain a 1. Penpa-Edit link for this puzzle to play it online. |

(for solvers: you might want to use the board I set up in Penpa: https://tinyurl.com/y983hozy)
Once I grasped the rules and figured out the logic, it was a pretty pleasant solve. I needed to pay attention to coordinates, but I didn't find it particularly difficult (maybe a little time-consuming). Well done. ^^
