Duality 3: Moody Killer Snakes by rockratzero
Normal sudoku rules apply. Each snake (gray line) is a modular line, meaning every three digits must contain a full set of digits modulo 3; ie they must come from {147}, {258}, {369}. A two-cell snake must contain digits from different modular classes. Each snake acts as a killer cage; the sum of digits on the snake sums to the small value given at the head of the snake. Digits may not repeat on the snake.
