Rules:

1. Standard Sudoku Rules
   Fill the grid with digits 1–9 so that each appears exactly once in every row, column. Also no digit should repeat within a region.


2. Region-Building Rules
   Construct regions made of orthogonally connected cells such that each region contains exactly one circle. Every cell belongs to a region. The number inside the circle gives the size of its region. Each region must contain a consecutive set of digits (e.g., {2,3,4}, {1}, {4,5,6,7,8,9}), in any order.


3. Black Kropki Dots
   A black dot between two cells indicates the digits are in a 1:2 ratio. The two cells must belong to the same region. Not all such dots are given.


4. White Kropki Dots
   A white dot between two cells indicates the digits are consecutive. The two cells must belong to the same region. Not all possible white dots are given.


5. Little Killer Sum
   Clues outside the grid, indicated by arrows, show the sum of the digits along the diagonal path of the arrow.
