Digits in cells separated by a black dot have a 1:2 ratio. - Killer Cages: Digits in cages must not repeat and must sum to the number in the upper left corner of the cage (if present). - Little Killers: Numbers outside the grid give the sum of all cells along the diagonal pointed to by the arrow. - Fog of War: Parts of the board are initially hidden. Entering correct digits will clear the fog in surrounding cells. No guessing is necessary.
