Theme: Black Hexagon
Author/Opus: This is the 221st puzzle from our contributing puzzlemaster Murat Can Tonta.
Rules: Standard Kakuro rules except on a hexagonal grid: Fill all empty hexes with digits from 1-9 so that all number clues (in white) indicate the sum of the digits in that direction. Digits cannot repeat in any entry (i.e., any group of hexes connected either horizontally or in one of the two diagonal directions, without any black cells separating them). This no repeat rule applies even for unclued entries.
Difficulty: 4 stars
Time Standards (highlight to view): Grandmaster = 7:45, Master = 10:00, Expert = 20:00
