Clues outside the grid are Parity Party clues and give the sum of the digits up to and including the first even digit or up to and including the first odd digit from that side. Single digit clues might give the first digit only. (i.e. a 7 clue could mean the first cell seen contains a 7, the first two cells contain an even and an odd that sum to 7, or the first two cells have a 24 pair and the third cell contains a 1.) Digits within cages cannot repeat, and sum to the small number shown. This puzzle is solved in two stages: Stage 1: Each 3x3 box is solved independently as a 3x3 “mean mini”. (ie each box uses exactly three digits from 1-9 without repeating in the rows or columns of that box.) Outside clues are for the first box seen in this stage (ie they “work” for the box next to the clue). Stage 2: Delete all digits except for the central cell of each 3x3 box. then solve the puzzle as a regular 9x9 sudoku using the remaining digits as givens. Outside clues can now see further than just the first box seen.
