Theme: V for Victory
Author/Opus: This is the 281st puzzle from our managing editor Serkan Yürekli.
Rules: Standard Kakuro rules. Also, a white circle between two cells shows that the digits in those cells are consecutive (i.e., they differ by 1). A black circle shows that the digit in one of the cells has twice the value of the other. If there is no circle between adjacent cells, neither of these properties holds. (Note: between 1 and 2, either a white or a black circle can be given.)
Difficulty: 4 stars
Time Standards (highlight to view): Grandmaster = 4:30, Master = 7:00, Expert = 14:00
