RULES : Classic Sudoku rules apply; Adjacent digits along each green line have a difference of at least 5; There are some cages in the grid. The number on the top left corner of each cage is equal to the sum of the digits in that cage. Digits do not repeat in a cage; The numbers with arrows outside the grid indicate the sum of the digits appearing in the cells in the corresponding direction. Digits may repeat in the direction of the arrow.
