Cracking the Cryptic - The Sudoku Worm of Phistomefel

Cracking The Cryptic is thrilled to introduce Sudoku Worms - small collections of sudoku puzzles, each from one of the World's most respected setters. Every Worm is a series of connected 6x6 or 9x9 sudokus where finishing one puzzle will give you one or two digits to use at the start of the next puzzle, and so on! Trying to finish all the puzzles in a Worm feels like a quest so good luck :)

Phistomefel’s worm consists of six puzzles of differing sizes, with some very innovative constraints!
