Standard 6x6 sudoku rules apply: each row, column, and 2x3 box must contain all the digits from 1 to 6.

Little Killer: clues outside the grid with an arrow show the sum of the digits along the indicated diagonal.

Sandwich: clues outside the grid without an arrow show the sum of the digits between the 1 and the 6 in the row or column.

Kropki pairs: black dots separate digits in a 1:2 ratio; white dots separate consecutive digits. Not all possible dots are necessarily given.
