1.2.25
Introducing CTC Worms!
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 more 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 :)
Marty Sears' worm consists of nine 6x6 puzzles - each using a new "glow-worm" constraint!
James Sinclair's worm consists of six 9x9 puzzles, each using a different standard constraint!
More worms coming soon!

Fog of War Pack Out Now!
Our long requested Fog of War pack is out now! Containing 50 puzzles (30 available now, 20 more releasing over the next few months) by some of the keenest minds and cleverest constructors there are. The sheer variety of uses of fog in this pack will amaze you.
In Fog Sudoku, some (or even all) of the grid is covered in a fog to begin with – and placing correct digits then clears some of the fog, allowing further clues to emerge.
This pack is designed for all skill levels, with beginner and intermediate players being able to solve a large percentage of the puzzles. Enjoy!
